From: Valentine Oradiegwu on 23 Jan 2010 18:49 Hello Everyone, I am a student who has been drafted to work on a moving object segmentation project. If i have a series of frames that make up a video, how can i select the best frame from the lot to use as a background frame for my background subtraction? Many thanks! Obi.

Each pixel should be the mode of all the pixels over time for that pixel location. Make sense?
