Convert a video to images and vice versa in C#

Question

Hello,

I need to convert an AVI movie into images (*.png), creating an image for each frame. Then, I'll run an algorithm I have (for Padestrian Detection - works on images). Last, I want to convert the "new" images, retrieved from the algorithm, to an AVI movie.

Can somebody please direct me to a code that does this kind of conversion in C#?

Thanks,

Gil.
