ChatGPT to API read tests

[shutterspeed1000]

Anyone trying to use ChatGPT or Gemini to read test tests? I have been getting pretty good results allowing it to match the API test samples to scanned cards or RGB charts I created.

Has anyone else tried this and gotten good results?

I have not asked ChatGPT for this type of help.

I suppose success depends on consistent lighting.

Interesting use case. Like @Dan_P said the biggest issue with color matching test is consistent lighting between the sample and the reference chart.

This is another reason why I use Hanna Checkers. Especially for items where there is a need for anything other than a binary understanding or a test that doesn’t use titration.

I personally wouldn’t trust ai with answering something like that (not to mention I wouldn’t trust api kits to begin with, haha). However, it is interesting that it is able to read the results and give you an answer on it

I have been getting pretty good results. I take the picture of the sample on a white background and I am getting results very close to my Hanna testers. If anyone else wants to try, here are the color charts I have made so far. I used linear interpolation to get smaller values. If anyone tries them let me know how it works for you. Zero guarantees it reads right, just for fun lol.

Fun experiment I will probably use at this point. I can't see color well at all so these keep me from bugging my wife.

I like your use of linear interpolation to define the color gradient. However, you need to ensure that you control for the consistency of light (similar to white balances for a picture) and recalibrate accordingly.

Yes, I use the background to set white balance. I am using these instructions in GPT4o to get the color.

Center Region Sampling: Use only the central region of the liquid in the test tube to avoid edge distortions caused by the glass curvature or lighting.

Averaging Multiple Areas: Divide the sample area into a grid and calculate the average color from multiple smaller regions to mitigate localized discrepancies

Crop to Relevant Area: Automatically crop to focus only on the liquid region of the test tube, avoiding borders or background.

Color Normalization: Normalize the image's color using background

Noise Reduction: Apply a Gaussian blur or similar technique to reduce random noise in the image

I scanned the original cards with my flatbed that has been profiled.

Amazing what python can do with image manipulation.

what are "test tests"?

Sorry, typo. API tests....

AI spellcheck fail...

I will always prefer "real" intelligence over "artificial" intelligence.

I have been using ChatGPT recently and it’s on point with its recommendations. I’ve been in the hobby and have been successful with a 160 gallon mixed reef for 4 years. The mistake I made was introducing a phosphate and carbon reactor. My sps didn’t like the quick drop and I dropped the photo of the weakened monti cap and it gave me some great advice. These guys were both thriving before adding that reactor. I’m running an algae scrubber 24 hr a day with no issues. Until the reactor dropped the p04. I’ll add a pic of it before showing my main tank. Lmk
