Hello Sai,

I understand that you want to track a circular blue dot in the videos that you have and then plot their coordinates.

I believe you could obtain the coordinates using the Computer Vision System Toolbox. Here’s the documentation link:

To address your specific question, I think “vision.PointTracker” System object might what you are looking for. Here’s a link that you can refer to for more information.

I hope this helps!
