please provide a matlab code for detecting changes in a sequence of images and picking the important ones.

We have a number of sequenced images from a video extractions. As it was a video there are minor changes in the frames. Need a matlab source code that will compare each and every image and if there is any abrupt change that frame will be saved in a designated folder.

1. determine what an "abrupt change" means in terms of images. Is it an abrupt change if the overhead lights are turned on? Is it an abrupt change if the Sun goes behind a cloud, darkening the ambient lighting?

3. determine if each frame meets the criteria
4. if it does, then imwrite()
