  • Use edge to detect edge
  • Use find to get coordinates (rows and columns of edge)
  • Calculate some center (approximately)
  • 123.png
  • Use cart2pol to calculate angle of each pixel
  • sort pixels by angle
  • Calculate new edge with smooth
Or another way:
  • Use edge to detect edge
  • imdilate object
  • Try bwmorph(I,'thin',inf) tu return to original image
