Hi I am implementing face detection in a live video feed.Now my code runs perfect when i debug it it is just when i actually run it does not show my imshow() function i-e nothing figure is not shown but my webcam is running(The light is on).
if true
FDetect = vision.CascadeObjectDetector;
x=0;
vidDevice = imaq.VideoDevice('winvideo', 1, 'YUY2_640x480', ... % Acquire input video stream
'ROI', [1 1 640 480], ...
'ReturnedColorSpace', 'rgb');
while(x<1)
rgbFrame=step(vidDevice);
BB = step(FDetect,rgbFrame);
imshow(rgbFrame);hold on
for i = 1:size(BB,1)
rectangle('Position',BB(i,:),'LineWidth',5,'LineStyle','-','EdgeColor','r');
end
hold off
end
end

You probably are showing the image to the current axes and as soon as the next frame from the web cam is available, it overwrites your image. Try using imshow with the 'Parent' option to display the image in a different axes than the live video is showing in.
