Hello,
I am processing a video file to track the displacement of an object. I am manually selecting the ROI now using imrect, but want to do an automatic selection that has a defined size and position of the ROI. Does someone have a code for this? or can suggest something?
It would be of great help if you could share something please.
Thank you.

Please note that imrect is no longer recommended.

If the region is known, i.e. if you can specify the desired rows and columns of the image, you can simply extract those rows and columns:
regionImage = frameImage(rowList,columunList);
If you wish to have an ROI that you can manipulate after it is initialized, consider the roi object rectangle method.
