Convert bwboundaries to graph

I want to convert bwboundaries data to a graph, so I can use findpeaks.

B = bwboundaries(L,'noholes');
imshow(label2rgb(L, @jet, [.5 .5 .5]))
hold on
for k = 1:length(B)
    boundary = B{k};
    plot(boundary(:,2), boundary(:,1), 'w', 'LineWidth', 2)
end

[EDIT] Formatted as code.

I don't think that is the right approach. Usually what is done is you find the centroid and find the distance of the boundary points to the centroid. Then you use findpeaks on those distances. I do that in my attached demos on shape recognition.
