WebMy approach lies in two steps, first I convert grayscale image to binary image using local thresholding or Otsu method, and then a medianfilter (python function medfilt). Result is shown below. Then, I use a thinning algorithm to extract the network's skeleton. Here is the result of my implementation of the Zhang-Suen thinning algorithm. WebThe segmented image was then used to obtain a skeleton of the vascular network by means of a thinning operation [41]. The skeletonization algorithm obtains the skeletons from binary images by thinning regions, i.e., by progressively eliminating border pixels that do not break the connectivity of the neighboring (eight-connected) pixels, thus ...
