fire frames tracking

Hi sir, I am a beginner of matlab user, my project is vision based fire detection, there is some problems that I can't solve it, can you please help me in my code?

In the code, I get the coordinate of motion object by using "Find" function, but how am I going to get the values of the pixels? help me please....

What do you mean by "the binary of the pixels"?

sorry....i mean the values of the pixels..
