Google Lens isn't going to include a menu item for every single computer vision task with a simple specialized solution.

OpenCV provides circle detection out of the box: https://docs.opencv.org/3.4/d4/d70/tutorial_hough_circle.htm... The only part that's somewhat difficult is tuning the parameters correctly. I've found setting all thresholds very low (generating lots of false positives) and then culling overlap to work very well when I had to count individual atoms in electron microscopy images a few years ago.

Well, yes, that's what the value provided by the service is.

This sounds very cool - what sort of order of magnitude numbers were they, and how accurate was it in the end?
