How can I convert an mpeg (or mpg) movie to ppm images, i.e. extract the
frames of an mpeg movie as images (could be ppm, tiff, whatever - since
I can convert it later from one format to another using image magik)? I
understand that an avi can be converted to frames (or image matrices) in
MATLAB. I am looking for a linux script solution, or even a C/C++ solution.
From google, I see that I can user 'convert' command to join ppm images
into an mpeg movie. But couldn't find to do the reverse.
I need this method to use the frames of a movie as training images to a
learning algorithm (to be used in background detection, for those who
may be interested).
thanks,
->HS
