I am learning my way in image processing by developing a frame difference program for an outdoor application using Grayscale. I have spent some time searching the forum but could not find a post specific to me question.
Basically, what are the optimal settings for:
Exposure? (auto …)
Grayscale Threshold values? How to decide?
Also, in an outdoor application, the scene will change continiously with time due to different lighting (day to night, cloudy to sunny …etc.). How does frame differencing handle that?
Your help is appreciated and thanks in advance.
