Frame Matching.

tailortrik0's icon

I would like know if there is an object that will select a frame that matches another.
Preferably I would like a bang when the matrix matches and when It doesn't.

I think it is a lot more simple that I am making it. Either the screen is a green/grey color, or there is video. I would like max to know when it is at the blank screen, and to start recording when it sees video.

I thought of taking the matrix values but im not sure I can do that much information with the sel object

any help?

thanks

These kinds of problems are usually pretty fun to patch together. If you know ahead of time what you are watching for, you can do some simple testing. The way I would do it is do frame-differencing between the incoming frame and your target image, then use jit.3m to analyze your difference image.
