From: Bluebird on 6 Aug 2010 16:10 I need to extract and process images from a webcam. The follwoing code does work however it is very slow (i.e. takes 0.67 to retrieve an image from the camera), the code which i found online is : %%%%%%%%%%%%%%%%%%%%%%%%%%%%% vid = videoinput('winvideo',1,'YUY2_320x240'); % Set video input object properties for this application. % Note that example uses both SET method and dot notation method. set(vid,'TriggerRepeat',Inf); set(vid,'ReturnedColorSpace','ycbcr'); start(vid); while(vid.FramesAcquired<=100) % Stop after 100 frames imgycbcr = getdata(vid); %Store image (This step takes 0.67 to process) % Do whatever process end stop(vid) %%%%%%%%%%%%%%%%%%%%%%%%%%%%% Can anybody please help me in making it faster or at least advice me about different command other than getdata() ? Thank you |
