Yesterday a friend of mine asked my opinion on a job they took. It's about using OpenCV.js to detect the the colors of a urine strip test from a smartphone camera in a web app.

We bounced some ideas on constraints and assumptions we cold make. Lighting conditions, support to hold the strip during the photo, operator skills, etc.

I showed them what ChatGPT 4 could produce and the result by just providing a prompt of 4 lines is mind-blowing.

Not only it produces code that is sound and works, but it suggested a different OpenCV API approach compared to the one I was thinking of (find contours vs. Haar-cascade detection) that is way simpler and probably more reliable (by just making some tweak to the image acquisition UX).

Impressive!
