Hello everyone, I'm feeling quite desperate and would appreciate some advice. Each spring for the past three years, when I open my pool, I run into a problem with the liner floating. To deal with this, I typically remove one of the return jet face-plates, attach a lubricated ABS pipe...

I totally understand your point. I don't want to use "unknown users'" pH meter as input data in what I'm doing. You are correct that unverified data don't belong in a statistical model. Again, my goal of gathering pictures is not about using them as "input data" per se. It's about testing...

Hi @AUSpool , I forgot to send the reply I had written for your previous post... :oops: I'm only using extra decimals for the development of my algorithm. In a production application, of course it would not show more than one decimal. That's also why I'm adding two green contours in the result...

Hi :wave:! Since I'm basing the comparisons of the pH "results boxes" column with the actual colors of the pH boxes in the picture instead of the "real" phenol red shades/hues/etc, that "bypasses" this problem. Of course, if the colors of your test kit are off (e.g. leaving your test block...

I tried to find AI models that would do what I want to do but found nothing that would fit. So I went the "old fashioned" way (statistical comparisons / normalizations). But if I get enough pictures and results, building an adaptable AI model is in the pipeline.

Well, of course the background color/lighting behind should be uniform for accuracy. Preferably white/bright with low contrast. The most important factor is the uniformity. I'm doing some statistical calculations along the phenol red column results but if they are very different shades, it would...
