Hi, I am working on a project to capture images via webcam in a predefined time interval, and continuously compare the images to a template (good image) and give an error if the difference is > tolerance set.

I working out using OpenCV. Would like to have advice how should I do it, e.g. best method, etc.

Appreciate if any one can help me on this. Thanks.
