Does your pixel intensity change? If not, you can estimate the location or index of that particular pixel using the find function and see how it changes everytime.

hi Sudheer Bhimireddy thanx for your response.

I already have location of pixels that i want to find motion of. Actullay the dificulty i m facing is that i have multiple pixels (8 to 10) and i want to find weather these particular pixels are moving or not. i know we can do this by finding the change in location in every frame to see which pixels are moving and which one are static. but how can i code this?

problem: some pixels leave the field of view and others enter the field of view. How can i handle that? we must have to ID/ label them. but as a begginer i m facing difculties in codding all this. please help me to code this as i tried many times but i condn't figure it one.
