How a video be processed in a original format(RGB format)?

Sir,

I have a codings to track the people in a video.My codings is

%Tracking people
  hsrc = vision.VideoFileReader('D:/videos/vi.avi', ...
                                'ImageColorSpace', 'Intensity', ...
                                'VideoOutputDataType', 'uint8');
  hfg = vision.ForegroundDetector(...
      'NumTrainingFrames', 5, ... % 5 because of short video
      'InitialVariance', 30*30); % initial standard deviation of 30
  hblob = vision.BlobAnalysis(...
      'CentroidOutputPort', false, 'AreaOutputPort', false, ...
      'BoundingBoxOutputPort', true, 'MinimumBlobArea', 10);

    hsnk = vision.VideoPlayer();
    while ~isDone(hsrc)
      frame  = step(hsrc);
      fgMask = step(hfg, frame);
      bbox   = step(hblob, fgMask);
      % draw bounding boxes around people
      out    = insertShape(frame, 'Rectangle', bbox, 'Color', 'green');
      step(hsnk, out); % view results in the video player
    end
    release(hsnk);
    release(hsrc);

But the video have been processed as a gray video. How can I process this in original RGB format.

        step(hsnk, out); % view results in the video player
      end
      release(hsnk);
      release(hsrc);

Notice that all that was changed was 'Intensity' became 'RGB'

Thank u sir!

Change 'ImageColorSpace', 'Intensity' to one of the RGB formats.

That's it. I have traced through the calls you use, and all of them should work with RGB frames.

Sir, How can convert the above output video into number of frames?
