  • Compare images after canny edge detection in OpenCV (C++)

    - by typoknig
    Hi all, I am working on an OpenCV project and I need to compare some images after canny has been applied to both of them. Before the canny was applied I had the gray scale images populating a histogram and then I compared the histograms, but when canny is added to the images the histogram does not populate. I have read that a canny image can populate a histogram, but have not found a way to make it happen. I do not necessairly need to keep using the histograms, I just want to know the best way to compare two canny images. SSCCE below for you to chew on. I have poached and patched about 75% of this code from books and various sites on the internet, so props to those guys... // SLC (Histogram).cpp : Defines the entry point for the console application. #include "stdafx.h" #include <cxcore.h> #include <cv.h> #include <cvaux.h> #include <highgui.h> #include <stdio.h> #include <sstream> #include <iostream> using namespace std;

  • How can i trace changes made to the DOM by JavaScript?

    - by Denis Hoctor
    I have a large website in development with a large amount of JS in different files. I have come across an issue where something is removing a class from the DOM. I can see it when I view source but not in Firebug. Normally I would place some alerts/console.log calls with the hasClass value but because I have no idea where to start I wanted to know if I can trace the change back when it occurs somehow? Denis

  • Can I pass a querystring that translates to a List<int> on the server?

    - by Denis Hoctor
    Hi all, I'm writing a Google Maps app that requests data from the server using jQuery's $.ajax() to send the request to my MVC Contoller. This control expects a List for the category types. What should the querystring look like for this? I've tried http://localhost:9090/mapamenities?amenityTypes=1,5 http://localhost:9090/mapamenities?amenityTypes=[1,5] with no luck. The SearchRquest attribute I'm trying to bind to is public List AmenityTypes { get; set; } Thanks Denis

  • Oracle Financial Analytics for SAP Certified with Oracle Data Integrator EE

    - by denis.gray
    Two days ago Oracle announced the release of Oracle Financial Analytics for SAP.  With the amount of press this has garnered in the past two days, there's a key detail that can't be missed.  This release is certified with Oracle Data Integrator EE - now making the combination of Data Integration and Business Intelligence a force to contend with.  Within the Oracle Press Release there were two important bullets: ·         Oracle Financial Analytics for SAP includes a pre-packaged ABAP code compliant adapter and is certified with Oracle Data Integrator Enterprise Edition to integrate SAP Financial Accounting data directly with the analytic application.  ·         Helping to integrate SAP financial data and disparate third-party data sources is Oracle Data Integrator Enterprise Edition which delivers fast, efficient loading and transformation of timely data into a data warehouse environment through its high-performance Extract Load and Transform (E-LT) technology. This is very exciting news, demonstrating Oracle's overall commitment to Oracle Data Integrator EE.   This is a great way to start off the new year and we look forward to building on this momentum throughout 2011.   The following links contain additional information and media responses about the Oracle Financial Analytics for SAP release. IDG News Service (Also appeared in PC World, Computer World, CIO: "Oracle is moving further into rival SAP's turf with Oracle Financial Analytics for SAP, a new BI (business intelligence) application that can crunch ERP (enterprise resource planning) system financial data for insights." Information Week: "Oracle talks a good game about the appeal of an optimized, all-Oracle stack. But the company also recognizes that we live in a predominantly heterogeneous IT world" CRN: "While some businesses with SAP Financial Accounting already use Oracle BI, those integrations had to be custom developed. The new offering provides pre-built integration capabilities." ECRM Guide:  "Among other features, Oracle Financial Analytics for SAP helps front-line managers improve financial performance and decision-making with what the company says is comprehensive, timely and role-based information on their departments' expenses and revenue contributions."   SAP Getting Started Guide for ODI on OTN: http://www.oracle.com/technetwork/middleware/data-integrator/learnmore/index.html For more information on the ODI and its SAP connectivity please review the Oracle® Fusion Middleware Application Adapters Guide for Oracle Data Integrator11g Release 1 (11.1.1)

  • Why did Apple remove Python support in Mavericks, aka Mac OS X 10.9?

    - by alex gray
    Apple has removed Python support (at least on the Developer level) in 10.9. Python IS still on the machine in /System/Library/Frameworks/Python.framework... but trying to link to Python using the 10.9 SDK fails. /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/System/Library/Frameworks does not have Python. I'm not a Pythonista, but find it interesting that Apple has made this change. I don't understand why this is done and I'm a bit annoyed that I have to remove Python from my compilation units in order to compile with 10.9 SDK. Is this a statement by Apple, along the lines of "People aren't using Python very much anymore so we're going to phase out support"? Or was something else driving the change?

  • How to use ImageMagick to batch desaturate images?

    - by Zando
    I have an image that is black text with some gray and pale yellowish background. I basically want to keep the text as black as possible, and make the gray and yellow comparatively lighter...at the very least, turn yellow into a light gray. What's the most efficient way to do that in ImageMagick?

  • Have you ever wondered...?

    - by diana.gray
    I've often wondered why folks do the same thing over and over. For some of us, it's because we "don't get it" and there's an abundance of TV talk shows that will help us analyze the why of it. Dr. Phil is all too eager to ask "...and how's that working for you?". But I'm not referring to being stuck in a destructive pattern or denial. I'm really talking about doing something over and over because you have found a joy, a comfort, a boost of energy from an activity or event. For example, how many times have I planted bulbs in November or December only to be amazed by their reach, colors, and fragrance in early spring? Or baked fresh cookies and allowed the aroma to fill the house? Or kissed a sleeping baby held gently in my arms and being reminded of how tiny and fragile we all are. I've often wondered why it is that I get so much out of something I've done so many times. I think it's because I've changed. The activity may be the same but in the preceding days, months and years I've had new experiences, challenges, joys and sorrows that have shaped me. I'm different. The same is true about attending the Professional Businesswomen of California (PBWC) conference. Although the conference is an annual event held at San Francisco's Moscone Center, I still enjoy being with 3,000 other women like me. Yes, we work at different companies and in different industries, have different lifestyles and are at different stages in our professional careers and personal lives; but we are all alike in that we bring the NEW me each year that we attend. This year I can cheer when Safra Catz, President of Oracle, encourages us to trust our intuition; that "if something doesn't make sense, it doesn't make sense". And I can warmly introduce myself to Lisa Askins, Cheryl Melching's business partner at Center Stage Group, when I would have been too intimated to do so last year. This year I can commit to new challenges such as "no whining, no excuses and no gossip" as suggested by Roxanne Emmerich, a goal that I would have wavered on last year. I can also embrace the suggestion given by Dr. Ian Smith to "spend one hour each day" on me - giving myself time to rejuvenate. A friend, when asked if she was attending PBWC this year, said "I've attended the conference several times and there's nothing new!" My perspective is that WE are what makes PBWC's annual conference new. We are far different in 2010 than we were in 2009. We are learning, growing, developing and shedding and that's what makes the conference fresh, vibrant, rewarding, and lasting. It is the diversity of women coming together that makes it new. By sharing our experiences, we discover. By meeting with one another professionally and personally, we connect. And by applying the wisdom learned, we shine. We are reNEW-ed. It shows in our fresh ideas, confident interactions, strategic decisions and successful businesses. This refreshed approach is what our companies want and need, our families depend on, our communities and nation look to for creative solutions to pressing concerns. Thanks Oracle for your continued support and thanks PBWC for providing an annual day to be reNEW-ed.

  • Is there a simple, flat, XML-based query-able data storage solution? [closed]

    - by alex gray
    I have been in long pursuit of an XML-based query-able data store, and despite continued searches and evaluations, I have yet to find a solution that meets the my needs, which include: Data is wholly contained within XML nodes, in flat text files. There is a "native" - or at least unobtrusive - method with which to perform Create/Read/Update/Delete (CRUD) operations onto the "schema". I would consider access via http, XHR, javascript, PHP, BASH, or PERL to be unobtrusive, dependent on the complexity of the set of dependencies. Server-side file-system reads and writes. A client-side interface element, accessible in any browser without a plug-in. Some extra, preferred (but optional) requirements include: Respond to simple SQL, or similarly syntax queries. Serve the data on a bare bones https server, with no "extra stuff", either via XMLHTTPRequest, HTTP proper, or JSON. A few thoughts: What I'm looking for may be possible via some Java server implementations, but for the sake of this question, please do not suggest that - unless it meets ALL the requirements. Java, especially on the client-side is not really an option, nor is it appealing from a development viewpoint.* I know walking the filesystem is a stretch, and I've heard it's possible with XPATH or XSLT, but as far as I know, that's not ready for primetime, nor even yet a recommendation. However the ability to recursively traverse the filesystem is needed for such a system to be of useful facility. At this point, I have basically implemented what I described via, of all things, CGI and Bash, but there has to be an easier way. Thoughts?

  • Is there a Moria like theme for Visual Studio 2010?

    - by Junior Mayhé
    Is there some cool Moria like theme for Visual Studio 2010? Mine is highlighting gray font with gray background! I just can't configure it on Tools-Options-Environment-Fonts and Colors menu. Visual Studio doesn't seem to show an item for this "highlighting keyword/tag system". You select a variable on variable called myVar, and it highlights all with the same name but with a grayer color and gray background. I just can't read it and can't set it.

  • Connecting Ubuntu home server to internet via laptop

    - by Gray-Wolfe
    I recently got a spare desktop computer from a relative to play around with and since I've been using Ubuntu for a few years I decided to install Ubuntu Server 12.04 to play around with and learn more. However it doesn't have a wireless card, the wireless adapter had a shipping error and will be awhile, and plugging it into the router is not an option. So I figured I could give it access to the wifi from my laptop(which I switch between Windows and Ubuntu) so I could at least get some things started and set up while I'm waiting for the adapter. However the few guides I can find to do that require a GUI, something lacking on the server version. Could someone tell me how to set this up via the terminal? I would appreciate it.

  • What's the difference between a "Release" Xbox 360 build and a "Debug" one?

    - by Sebastian Gray
    I've got a build of my game that works on Windows under a release and debug build as expected. When I deploy the debug version of the game to the Xbox, it works as expected and runs the same as on Windows - however when I deploy the release version to the XBOX I get different behaviour within the game. I'm using a 3rd party library for the collisions (which is where I am seeing differences between the release and debug versions of my game); so I can't see what's actually different but I suspect they have some compiler directive for Debug on the Xbox to the Release version on the Xbox. As such, I'm thinking that I may need to release my game with the Debug build instead of the Release build but I want to know what issues I can expect by doing so? Are there any significant performance issues between the two build profiles?

  • How does having the Debugger change the game execution on an XBOX 360?

    - by Sebastian Gray
    So I thought my issue was relating to the difference between a Debug and a Release build as per this question: What's the difference between a "Release" Xbox 360 build and a "Debug" one? but I've since found that if I go ahead and build a Creators Club version of the game using a Debug build and deploy to the XBOX, I get the same experience I had with the Release version of my game. However if I run the game from Visual Studio using F5 and having set the XBOX as the default platform, then the game runs as expected. If I change from Debug to Release and run with CTRL+F5 then the game also works as expected. How would running the game with the debugger attached change the results I am getting in game? Is there any way that I can use the same approach or change the default compilation of the game so that I can use this approach to release my game?

  • Setting up fastcgi on an Ubunutu server (socket file permissions issue)

    - by gray alien
    I am trying to set up mod_fcgid on my server. Part of the requirement is that Apache needs to create a socket file for mod_fcgid. I specified the folder for Apache to write the socket data to: /var/run/apache2/fcgid I then specified this file in my fcgid.conf file as follows: SocketPath /var/run/apache2/fcgid/sock I then changed the owner of the folder to www-data (the apache user) and gave the owner full permissions to the folder and its contents. I was able to run my test fcgi app then. When I rebooted the machine, y fastcgi app no longer worked. After some investigation, I found that ownership of /var/run/apache2/fcgid has been reset to root, and with permission reset to 700 I have the following questions: Is there something specific about the /var/run folder? why is the permissions being reset after a reboot? Should I move my socket file to another location (in case root automatically takes ownership of contents in this folder for security reasons?) I am running Ubuntu 10.0.4 LTS 64 bit

  • Google Maps & jQuery InfoWindow Replacement

    - by Denis Hoctor
    Hi all, So I'm rewriting my first google maps app and I'm looking at how I create info windows on click of a marker and it seems very inefficent to be adding a listener for each. Previously I've used GInfoWindow and EBubble (http://econym.org.uk/gmap/ebubble.htm). I was thinking that I could use jQuery to show a div with dynamic data if I had a hook for each marker to show the window and relevant marker info (pulled from JSON). I can see each marker has a unique id (e.g. mtgt_unnamed_2822) but I'm not sure how to predicte this. Has anyone tried this before or know how to go about it? Thanks Denis

  • Is it a good object-oriented-design practice to send a pointer to private data to another class?

    - by Denis
    Hello everyone, There is well known recommendation not to include into class interface method that returns a pointer (or a reference) to private data of the class. But what do you think about public method of a class that sends to another class a pointer to the private data of the first one. For example: class A { public: void fA(void) {_b.fB(&_var)}; private: B _b; int _var; }; I think that it is some sort of data hiding damage: the private data define state of their own class, so why should one class delegate changes of its own state to another one? What do you think? Denis

  • How can I differentiate between smart phones and others?

    - by Denis Hoctor
    Hi all, I'm looking to revamp our mobile site with something simple for phones below the ambiguous smart phone category and something a little more interesting for the phones above this category. I'm not interested in WAP/WML for this project. I'm building a ASP.Net 4 MCV 2 app and using MBDF What I'd like to know is how best to define this differentiation when using MBDF? Screen size, Javascript, SpportsTouchScreen etc. are all in MBDF along with others but I'm not sure where to draw the line and where the data is most accurate for the broad number of devices. What do those of you out there developing for this spread of hardware & software split on? Thanks, Denis P.S. I've done my research on xHTML MP1.0 - 1.2 and the best practises for implementation to ensure broad coverage but I don't want to restrict the newer phones out there to what the base line can see.

  • How to generate entity classes from nhibernate mapping files during runtime.

    - by Denis Rosca
    Hello, i need some help with c# and nhibernate. I'm working on a project that requires the entity classes to be generated from hbm files at runtime. I get the mapping files from a service, and then need to generate the classes dynamicaly and configure nhibernate to use them. The problem is that i'm new to nhibernate and not much of a pro in c#, so me writing the piece of code that achieves this is very error-prone. I was wondering if you know of any open source software that i could use. Worst case scenario (if can't find anything that even remotely resembles what i need), do you guys have some advice on where should i start? Maybe some links ? Thanks, Denis.

  • Is using iframes to improve page performance an acceptable approach?

    - by Denis Hoctor
    Hi all, I have a complex page that has several user controls like galleries, maps, ads etc. I've tried optimising them by ensuring full separation of html/css/js, placing js at the bottom of the page and trying to ensure I have well written code in all 3 but alas I still have a slow page. It's not really noticeable to a modern browser but can see the stats and IE6/7. So I'm now looking to do what we've done previously for Adtech flash crap - an iframe. Apart from the SEO impact which I'm not worried about in the case of these controls, what do people think of this as an approach? PROS and CONS please. Thanks, Denis

  • How can I drag from a connected vertical list to the first item of a another list below with jQueryUI Sortable?

    - by Denis Hoctor
    Hi all, I have have several ULs vertically down a page. They are setup using jQueryUI's sortable(). My live example is: http://jsfiddle.net/pborreli/pJgyu/ I can drag from answers to make it the final element in questions. But when I drag from questions to answers the placeholder jumps to the second item in the questions list. At that point I can then drag it to the top. Any ideas why I am having this issue dragging from a list above to the first element of a list below? I've tried editing the padding and margin on both the lists and the sortable items. Thanks, Denis
