Code:
video='ATMvid.avi'
if ischar(video)
% Load the video from an avi file.
avi = aviread(video);
pixels = double(cat(4,avi(1:frameSkip:end).cdata))/255;
clear avi
else
% Compile the pixel data into a single array
pixels = double(cat(4,video{1:frameSkip:end}))/255;
clear video
end;
Error-??? Error using ==> double
Maximum variable size allowed by the program is exceeded.
Error in ==> extractForeground at 80
pixels = double(cat(4,avi(1:frameSkip:end).cdata))/25;

Read it a frame at a time using VideoReader() and read(). Don't try to suck up the whole movie at once into the program. Some videos can be huge - like gigabytes and won't fit into memory. Most likely you can get by with having just a few frames in memory at one time.
