Say I have a complex shape like this
that I want to describe/simplify like this
I was wondering if there was a way using image analysis to do this ? I can find many methods of shape recognition but not any for shape simplification (althoug I'm not an expert and my searching might not be efficient...). I tried using clustering methods (cmdscale on distance between points and linkage/cluster) but the results is not easy to get, especially if I don't know beforehand the number of clusters.

You could threshold the image to produce blobs using imbinarize().
You could separate the blobs using imerode().
You could smooth the blobs shapes using conv2() or imfilter().

Very promising ! Thank you very much, I'll give it a try (I'll update with the results if it works)
