Re: brightest red spot detection
Now i am able to track the red dot but the problem is that i get a cluster of red pixels so the tracked dots are not stable when i get the pixels from successive frames. I tried to find the pixel using the first red spot but that reduced the problem to a small extent. So kindly tell me how i can stabilize the dot across multiple frames.

Hello BharatT,
I am glad you have managed to move forward. Is it possible to post your code?
I have no experience in this what so ever and I wouldn't know where to begin!
Hopefully another member here will be able to help you.
If I find any new information I will post back asap.
