LOL you're not getting this done trivially with OpenCV. https://countthings.com/en/counting-templates

amassing a library of scripts for various shapes is time-consuming, true. however few of those templates do anything that openCV can't be massaged to do well, too. Given that people are likely going to use only a few of the templates that they find useful for their own work, I find it hard to be able to find the value in paying 100/mo for a massive library filled with techniques that aren't useful for my particular w…

No, with many of the templates you quickly go well beyond "massaging". Not saying it can't be done, but you vastly oversell the triviality of it.

Instance segmentation.

Thanks for this, maskrcnn looks like an interesting candidate

also U-net is great at this stuff, and a bit easier to implement for my taste. there are many ready implementations over the internet

Is ML here needed? When I was working in a lab we used the opensource ImageJ for counting cells. It seems like it'd do a great job here too. https://en.wikipedia.org/wiki/ImageJ

A colleague of mine recently published a paper on ML-based cell counting for human cancer cells. It's open access and available here https://www.mdpi.com/2076-3417/11/11/4912

Couldn't they use a machine like a coin counter?

The new camera approach obviously is a lot more accurate, powerful and simple now once you have it.

But totally agree looking at their previous solution it feels extremely primitive. There surely must have been a simple middle ground without the app, using a mechanical funnel, a wheel or one-dimensional photosensor to count these. Even if they are different sizes and not always exactly round, the shape and size is still rather uniform.

Do you have any recs in North Seattle? Me and my wife live in Lake City and have been looking for a good (need not be the best ;) ) Mexican place.

Hello former neighbor. :-) (Lived in Lake City for four years) Casa Del Mariachi (off 125th) has great breakfast burritos. Haven’t tried the rest of their food, only came across them recently. Should be good though. Azteca by Northgate is only okay if you don’t want to go far, you could do a lot better. Plaza Garcia is your classic southwest Mexican food and one of our favorites. It’s in Kirkland but worth the drive.…

Thanks for the recs! Me and my wife went to Casa del Mariachi the other day and the breakfast burritos were bomb as promised :) Definitely going to try that Whidbey day trip sometime as well!
