  • Categorize the approximate shape of an array of Points in 3D Space

    - by user1295133
    I have a set of points in 3d space and I want to be able to categorize the shape that best fits them - cube, sphere, cylinder, planar (flat) etc. I've looked at supervised/machine learning but since I need first generate a large training data set that's not really suitable. My dream solution would be a java library with a wonderful magical function something like : public enum ShapeType { CUBE, SPHERE, CYLINDER, PLANAR } public ShapeType CategorizeShapeFromPoints( 3DPoint[] points ) However, any and all help will be appreciated. Thanks

  • Wav analysis in python

    - by mudder
    I'm looking for a python library that will help me analyze the audio in wav files.

  • machine learning and code generator from strings

    - by BCS
    The problem: Given a set of hand categorized strings (or a set of ordered vectors of strings) generate a decision function to categorize more input. The question: are there any tools out there that will do that? I'm thinking of some kind of reasonably polished, download, install and go kind of things, as opposed to to some library or a brittle academic program.

  • Flex: convert VideoPlayer.currentTime to string "00:00:00:000"

    - by numediaweb
    Hi there! what about this one: I want to format the currentTime displayed by a videoPlayer component inside flex, something like : 8230.999 to something like 01:59:59:999 which is "hours:minutes:seconds:milliseconds" I trie different sets of codes but they can't get it to work because currentTime is nor a correct miliseconds time as it adds a floating 3 digit point to seconds; so instead of : 2000ms it outputs 2.000 something people like me just can't understand! thanx for any help :) ### UPDATE I still have problem with milliseconds. here's the current MXML: <?xml version="1.0" encoding="utf-8"?> <s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600"> <fx:Script> <![CDATA[ protected function convert_clickHandler(event:MouseEvent):void { var val:Number = new Number(inPut.text); //inPut.text = 1000.001 //val = val * 1000; outPut.text = timeFormat(val); } public static function timeFormat(value:Number):String { var milliseconds:Number = value % 1000; var seconds:Number = Math.floor((value/1000) % 60); var minutes:Number = Math.floor((value/60000) % 60); var hours:Number = Math.floor((value/3600000) % 24); var s_miliseconds:String = (milliseconds<10 ?

  • Storing dynamic fields in Django forms

    - by hekevintran
    Django's form library has a feature of form sets that allow you to process dynamically added forms. For example you would use form sets if your application has a list of bookmarks you could use form sets to process multiple forms that each represent a bookmark. What about if you want to dynamically add a field to a form? An example would be a survey creation page where you can dynamically add an unlimited number of questions. How do you handle this in Django?

  • R: getting "inside" environments

    - by Mike Dewar
    Given an environment object e: > e <environment: 0x10f0a6e98> > class(e) [1] "environment" How do you access the variables inside the environment? Just in case you're curious, I have found myself with this environment object. I didn't make it, a package in Bioconductor made it. You can make it, too, using these commands: library('GEOquery') eset <- getGEO("GSE4142")[[1]] e <- assayData(eset)

  • HTML / CSS autonumber headings?

    Is there a way (ideally easy) to make headings and sections autonumber in HTML/CSS? Perhaps a JS library? Or is this something that is hard to do in HTML? I'm looking at an application for a corporate wiki but we want to be able to use heading numbers like we always have in word processors.

  • Is there a method in Java that allows me to replace all HTML special characters into their encoded e

    - by Siracuse
    I have a textfile which my Java program is modifying and putting into an HTML file for display. However, this textfile contains lots of HTML unsafe characters such as "<" and the "" which would need to be encoded into & gt; (sans space) and & lt;. Is there some library method I can use to sanatize my text document to replace all these HTML special characters with their safe encoded equivelants?

  • How to get the EJB listening port?

    - by Alotor
    I'm currently developing a library for monitoring calls to several remote services (WebServices, EJBs...). One of the parameters that i would like to register is the port from which a EJB is called (a Stateless Session Bean invoked like a remote object) There is any standarised way of getting the port? Or should I inspect the JNDI tree for this kind of information? I'm using the EJB 2.1 spec, but it's also posible for me to use EJB 3

  • Erlang : Handling HTTP Requests and Responses

    - by Ted Karmel
    What is the best erlang library for processing http requests and responses from within an erlang application? I have taken a look at inets but as a standalone application, it seems more like a replacement for curl. I would like to access external APIs from within the erlang application so would need to parse responses and be able to make subsequent requests with cookies generated from the response.

  • decent html5 offline storage and caching examples

    - by Nils
    I'm keen to test out html offline storage and caching with a view to developing a prototype to show off the offline web application capabilities of html5. I've found some webkit-specific samples, but I'm battling to find any decent code samples that even work at all in Firefox 3.6 For a sample, I'd be happy with something that works with the following: Our company uses jquery extensively so I'd prefer samples that use that library or pure javascript. It should at least work on firefox (3.6+ is fine) Can anyone point me to some links that provide some guidance and code samples?
