You can get each frame with the following code. And deal with it as an image.
vidobj = vision.VideoFileReader('filename')
viewer = vision.DeployableVideoPlayer;
for N = 1:numframe
I = step(vidobj);
% write image processing algorithm here
Iout = *******
step(viewer, Iout)
end
where, numframe is number of frame.
Computer Vision system toolbox is required.
