Hi,
Using the example i have successfully drawn the outline on the object.
OUTLINE.png
But it is showing glitches of up and downs on the surface.

Cany anyone pls help me in doing it.

Thanks Matt J
There is no exact thing which determines the radius of this circle.

  • 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
