Could be useful for the navigator.

❌ Thickness estimation using an elliptical area don't give good results for now. Results depend on other parameters such as the distance between the coin and the different aliments etc.

Heights of the aliments could be measured using ARCore or ARKit, it seems that it would required 2 separate implementations for iOS and Android support. Would it be convenient for the user ?

One easier path would be to take a 90 degrees picture with the coin, and give the possibility to the user to adjust the results.

Thickness is computed dynamically with user feedback. See volumeList() function. It only takes into account the classes from the first picture.

It's a first try, we should be careful of what exactly is computing here to make sure it's the right behavior.

[leopoldmaillard]

BUG : thickness could be negative using the sliders.

[leopoldmaillard]

Behavior when we have different classes between the first and the second picture : only the classes that are BOTH in the first and the second picture are retained for volume estimation.

I close the issue. We may change some algorithm for improvement in the future.
