Measure along / within ROIs

Not sure if this is within the scope of the project, but it would be nice to be able to measure along ROIs (e.g. a "profile line" through that moves through space in one (more, eventually?) axis. Through lines, it could be a profile line. With polygons, it could be average intensity (or any other function that takes a set of pixels and returns a number), or a profile line along the circumference of the shape.

Something like this as an example of the profile line:

I worked on something like this a couple of years ago, and might give it a shot when I have the time, but I thought I'd leave this here so I could remember, and if it inspired anyone else to give it a shot since I think it'd be very useful!

L’issue ne nomme aucun fichier, test ou point d’entrée. Commencez par examiner les points d’entrée existants du repository pour les ROI et le plotting, puis clarifiez si les profils de ligne, l’agrégation de polygones et les profils de circonférence sont inclus dans le périmètre. La tâche doit être considérée comme terminée lorsque les mesures de ROI prises en charge et leur comportement attendu sont explicitement définis.
