Set a specific target area for HoughCircles?

Python
1

Currently have hough circles setup and need to add a mask / limit to where the circles are detected I tried to mess with the parameters on it such as adding a high dist and all that did was make the one outline jump sporadically from circle to circle ideally I need it to only apply the houghcircle to the center of the camera in a very limited area.

Anyone have an Idea?

slice a subregion, work on it, transform (add offsets to) resulting coordinates back into whole region.

Got a possible docs page for slicing? Don’t need to be spoon fed just don’t know what this is yet but willing to put the research in. :slight_smile:
