QUESTION
I have collection which is a field in a struct in some module. I want to update all the values in the collection from another module.
I wrote some code to mimic what I want to achieve. It's shortened a bit, but I think it has all needed parts. There is no struct holding the collection in this code, but imagine this is a getter which returns the collection. I added in comments how I think it should look.

doesn't implement impl<'a, T> IntoIterator for &'a mut BTreeSet
(that would break the tree).
You can only do this with types that implement IntoIterator
with mut
like impl<'a, T> IntoIterator for &'a mut Vec
, example.
QUESTION
I'm trying to count dendritic spines (the tiny protuberances) in mouse dendrites obtained by fluorescent microscopy, using Python and OpenCV.
Here is the original image, from which I'm starting:
Raw picture:
After some preprocessing (code below) I've obtained these contours:
Raw picture with contours (White):
What I need to do is to recognize all protuberances, obtaining something like this:
Raw picture with contours in White and expected counts in red:
What I intended to do, after preprocessing the image (binarizing, thresholding and reducing its noise), was drawing the contours and try to find convex defects in them. The problem arose as some of the "spines" (the technical name of those protuberances) are not recognized as they en up bulged together in the same convexity defect, underestimating the result. Is there any way to be more "precise" when marking convexity defects?
Raw image with contour marked in White. Red dots mark spines that were identified with my code. Green dots mark spines I still can't recognize:
My Python code:

This way, you will have many vertices that you have to filter: looking at the angle of each vertex you can tell if it is concave or convex. Each spine is one or more convex vertices between concave vertices (if you have several consecutive convex vertices, you keep only the sharper one).
EDIT: in order to compute the angle you can do the following: let's say that a, b and c are three consecutive vertices
