What is size(avi) and size(avi(1).cdata) and class(avi(1).cdata) ?

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.

I am using mixture of Gaussians algorithm for background subtraction,showing me output also, but not clearly distinguishing foreground and background, showing blurred video wherein sometime foreground and background video looks similar , what could be done to show it clearly.

Use better algorithms, I guess.
