Hello
Working on a segmentation of 3D CT images. Sometimes when my segmentation algorithm ( Smoothing, thresholding, 8 connected...) runs to extract the region bone, do not produces always (85 %) close contour . So "imfill (..., 'holes')" not works automatically. In fact it's possible (80 %) to take it correctly by imdilate and imerode with a big structring element but I will lose accuracy.
So my problem is :
  • Test the closure contour of each slice
  • Closing the open contour
Please if you have any idea let me know (websites, courses, ...)
Thank you
