I am trying to locate white circles on a dark, consistent and static background. I was originally using a standard lens and find_circles pretty successfully. I experimented with a fisheye and realized how much more area I can cover. The downside is that the circles are so small that the find_circles algorithm doesn’t seem to find them (as low as a 2 pixel radius.) I looked at find_blobs, but unlike the find_circles method there is only a minimum blob size and no upper bound. I know I can filter after the fact with blob.area, but I was wondering if putting an upper bound to the find_blobs would improve performance like it does withe find_circles.
