Hi! I have a skeleton image (the attached one) and i want to compute how many branches there are for each branch point. Eg: there are two branchpoints with four branches, three branchpoints with three branches, etc. Anyone knows how to do this?

Perhaps as follows:
k=ones(3); k(5)=0;
neighborCount=conv2(double(BW),k,'same');
neighborCount=neighborCount.*(neighborCount>2);
[row, col, numBranches]=find(neighborCount); %branch point (row,col) coordinates and number of branches.
