Hi, I want to detect the black points(Only on the pattern of the mag). I am working on hand movement disorder analysis and i want to track all points marked on mag in one simple video.plz help me.

This is the 1st frame of my video.

Have you tried any of the tracking examples in the Computer Vision System Toolbox?

Once you adapt code from that, then perhaps someone can help you if you still need it.

I tried for this but don't get exactly how this fulfill my requirements.please help me.

Then see if you can adapt this demo where I track a green Sharpie pen in a video.

I think this is perfectly that i want.Thank you so much.Sorry if i ask u silly question but i have onr more question is that how i get that hThresholds,sThresholds,vThresholds values for my black point???

[Image Analyst]

Experiment around. For black, s should be less than about 0.1, and v should be less than .2 or .3 or so. h should not matter.

can you please mark the answer "Accepted" if it works for you. Thanks in advance.
