I have successfully extracted nodes(nodes), edges(lines), arrows from image. Facing difficulty in finding Relations and indegree & outdegree of node. sample input and output image is attached. On Thu, Nov 29, 2018 at 5:08 PM Leena Chourey <leenagour@gmail.com> wrote:

I would like to generate a skeleton out of an image. The resulting output of the skeleton image has disconnected edges.

imgfile = "Bagah.jpeg" im = cv2.imread(imgfile) image = cv2.cvtColor(im, cv2.COLOR_BGR2GRAY) thresh = threshold_mean(image) thresh = threshold_mean(thresh)
binary = image > thresh #dilate = skimage.morphology.binary_dilation(binary) gaussian = skimage.filters.gaussian(binary) edges = filters.sobel(gaussian) #dilate = feature.canny(edges)#binary,sigma=0) skeleton = skeletonize_3d(gaussian)#binary) fig, axes = plt.subplots(nrows=2,ncols=2, figsize=(8, 2)) ax = axes.ravel() ax[0].imshow(gaussian, cmap=plt.cm.gray) ax[0].set_title('gaussian')
ax[1].imshow(skeleton, cmap=plt.cm.gray) ax[1].set_title('skeleton') for a in ax: a.axis('off')
plt.show()
Please find the attachments of my input and output files. I would like to translate this skeleton into a graph with nodes and edges. Could someone suggest how to obtain a skeleton with connected edges?
