  • Motion detection information

    - by dotnetdev
    Hi, I know the AFORGE.NET API has motion detection algorithms, but what would be a good book to learn these algorithms with C# samples (the AFORGE.NET code is complex and not commented enough to help). Thanks

  • What's a good matrix manipulation library available for C ?

    - by banister
    Hi, I am doing a lot of image processing in C and I need a good, reasonably lightweight, and above all FAST matrix manipulation library. I am mostly focussing on affine transformations and matrix inversions, so i do not need anything too sophisticated or bloated. Primarily I would like something that is very fast (using SSE perhaps?), with a clean API and (hopefully) prepackaged by many of the unix package management systems. Note this is for C not for C++. Thanks :)

  • lightweight publish/subscribe framework in java

    - by mdma
    Is there a good lightweight framework for java that provides the publish/subscribe pattern? Some ideal features Support for generics Registration of multiple subscribers to a publisher API primarily interfaces and some useful implementations purely in-memory, persistence and transaction guarantees not required. I know about JMS but that is overkill for my need. The publish/subscribed data are the result of scans of a file system, with scan results being fed to another component for processing, which are then processed before being fed to another and so on.

  • Soundcloud uploading to specific set/playlist

    - by user1492347
    I'm uploading some audio to soundcloud, but would like to add the audio to a specific playlist i have also created, without making an extra request (see "Adding Sounds to a Set" http://developers.soundcloud.com/docs/api/guide#uploading). Is it possible to upload directly to a playlist? Alternatively, I could send an extra request to add the track to the playlist but how would you do this in AS3. I see examples for JavaScript but am unsure how this would work in Flash.

  • JSONArray does not work when I am getting the JSON string from the server

    - by Taehoon A Kim
    I've looked up some answers but am not sure why mine is failing exactly... The code looks something like this HttpResponse httpResponse = httpClient.execute(httpPost); HttpEntity httpEntity = httpResponse.getEntity(); String json = EntityUtils.toString(httpEntity); //Convert to JsonArray JSONArray jsonArray = new JSONArray(json); Log.i(DEBUG_TAG, Integer.toString(jsonArray.length())); for (int i = 0; i < jsonArray.length(); i++) { JSONObject jsonObject = jsonArray.getJSONObject(i); Log.i(DEBUG_TAG, jsonObject.getString(KEY_ID)); // creating new HashMap HashMap<String, String> map = new HashMap<String, String>(); // adding each child node to HashMap key => value map.put(KEY_ID, jsonObject.getString(KEY_ID)); map.put(KEY_TITLE, jsonObject.getString(KEY_TITLE)); map.put(KEY_ARTIST, jsonObject.getString(KEY_ARTIST)); map.put(KEY_DURATION, jsonObject.getString(KEY_DURATION)); map.put(KEY_VOTECOUNT, jsonObject.getString(KEY_VOTECOUNT)); map.put(KEY_THUMB_URL, jsonObject.getString(KEY_THUMB_URL)); map.put(KEY_GENRE, jsonObject.getString(KEY_GENRE)); //Adding map to ArrayList if (Integer.parseInt(jsonObject.getString(KEY_VOTECOUNT)) == -1){ //If VoteCount is -1 then add to header headerList.add(map); }else { songsList.add(map); } } } catch (UnsupportedEncodingException e) { e.printStackTrace(); } catch (ClientProtocolException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } When I run logcat on String json, it seems to show correct info which is kind of like this... { "userdata": [ { "id": "8", "title": "Baby One More Time", "artist": "Britney Spears", "duration": "03:24:00", "votes": "0", "thumb_url": "http://api.androidhive.info/music/images/dido.png", "genre": null }, { "id": "2", "title": "As Long As You Love Me", "artist": "Justin Bieber", "duration": "05:26:00", "votes": "0", "thumb_url": "http://api.androidhive.info/music/images/enrique.png", "genre": "Rock" } ] } and the logcat on JSONArray jsonArray = new JSONArray(json); tells me that jsonArray.length() 10-31 22:57:28.433: W/CustomizedListView(26945): error! Invalid index 0, size is 0 Please let me know Thank you,

  • MKMap showing detail of annotations

    - by yeohchan
    I have encountered a problem of populating the description for each annotation. Each annotation works, but there is somehow an area when trying to click on it. Here is the code. the one in bold is the one that has the problem. -(void)viewDidLoad{ FlickrFetcher *fetcher=[FlickrFetcher sharedInstance]; NSArray *rec=[fetcher recentGeoTaggedPhotos]; for(NSDictionary *dic in rec){ NSLog(@"%@",dic); NSDictionary *string = [fetcher locationForPhotoID:[dic objectForKey:@"id"]]; double latitude = [[string objectForKey:@"latitude"] doubleValue]; double longitude = [[string objectForKey:@"longitude"]doubleValue]; if(latitude !=0 && latitude != 0 ){ CLLocationCoordinate2D coordinate1 = { latitude,longitude }; **NSDictionary *adress=[NSDictionary dictionaryWithObjectsAndKeys:[dic objectForKey:@"owner"],[dic objectForKey:@"title"],nil];** MKPlacemark *anArea=[[MKPlacemark alloc]initWithCoordinate:coordinate1 addressDictionary:adress]; [mapView addAnnotation:anArea]; } } } Here is what the Flickr class does: #import <Foundation/Foundation.h> #define TEST_HIGH_NETWORK_LATENCY 0 typedef enum { FlickrFetcherPhotoFormatSquare, FlickrFetcherPhotoFormatLarge } FlickrFetcherPhotoFormat; @interface FlickrFetcher : NSObject { NSManagedObjectModel *managedObjectModel; NSManagedObjectContext *managedObjectContext; NSPersistentStoreCoordinator *persistentStoreCoordinator; } // Returns the 'singleton' instance of this class + (id)sharedInstance; // // Local Database Access // // Checks to see if any database exists on disk - (BOOL)databaseExists; // Returns the NSManagedObjectContext for inserting and fetching objects into the store - (NSManagedObjectContext *)managedObjectContext; // Returns an array of objects already in the database for the given Entity Name and Predicate - (NSArray *)fetchManagedObjectsForEntity:(NSString*)entityName withPredicate:(NSPredicate*)predicate; // Returns an NSFetchedResultsController for a given Entity Name and Predicate - (NSFetchedResultsController *)fetchedResultsControllerForEntity:(NSString*)entityName withPredicate:(NSPredicate*)predicate; // // Flickr API access // NOTE: these are blocking methods that wrap the Flickr API and wait on the results of a network request // // Returns an array of Flickr photo information for photos with the given tag - (NSArray *)photosForUser:(NSString *)username; // Returns an array of the most recent geo-tagged photos - (NSArray *)recentGeoTaggedPhotos; // Returns a dictionary of user info for a given user ID. individual photos contain a user ID keyed as "owner" - (NSString *)usernameForUserID:(NSString *)userID; // Returns the photo for a given server, id and secret - (NSData *)dataForPhotoID:(NSString *)photoID fromFarm:(NSString *)farm onServer:(NSString *)server withSecret:(NSString *)secret inFormat:(FlickrFetcherPhotoFormat)format; // Returns a dictionary containing the latitue and longitude where the photo was taken (among other information) - (NSDictionary *)locationForPhotoID:(NSString *)photoID; @end

  • Processing image data in java me

    - by Trimack
    Hi, I want to process raw data from a picture taken in java me with byte[] snap = videoControl.getSnapshot(encoding); My question is, whether I should try working already with snap or should I first create the image from this array Image im = Image.createImage(snap, 0, snap.length); and then work with that? Or is there some better documentation of both methods, i.e. getSnapshot and createImage than the Java API reference?

  • DRY Ruby Initialization with Hash Argument

    - by ktex
    I find myself using hash arguments to constructors quite a bit, especially when writing DSLs for configuration or other bits of API that the end user will be exposed to. What I end up doing is something like the following: class Example PROPERTIES = [:name, :age] PROPERTIES.each { |p| attr_reader p } def initialize(args) PROPERTIES.each do |p| self.instance_variable_set "@#{p}", args[p] if not args[p].nil? end end end Is there no more idiomatic way to achieve this? The throw-away constant and the symbol to string conversion seem particularly egregious.

  • Does Scheme work with Microsoft COM?

    - by Martin
    I'm new to Scheme -- the functional programming language and I like it a lot for its first-class/higher-order functions. However, my data comes from a COM source with an object-oriented API. I know Scheme and COM belong to different programming paradigms, but I'm wondering if there is any interface or a way for Scheme to connect to a COM source? Thanks.

  • Can I use relative XPath expressions in libxml2?

    - by brbr
    I am wondering whether it is possible to use relative XPath expressions in libxml2. This is from the javax.xml.xpath API and I would like to do the similar thing using libxml2: Node widgetNode = (Node) xpath.evaluate(expression, document, XPathConstants.NODE); With a reference to the element, a relative XPath expression can now written to select the child element: XPath xpath = XPathFactory.newInstance().newXPath(); String expression = "manufacturer"; Node manufacturerNode = (Node) xpath.evaluate(expression, **widgetNode**, XPathConstants.NODE);
