[Insight-users] Image Processeing question/ Filling holes

[Luis Ibanez]

Hi Zein,

Unless the holes are really big, you
are probably ok doing Mathematical
Morphology.

A sequence of dilation/erosion will
close the holes. You will have to
play with the size of the structuring
element.
(assuming that black is the object).

You may want to take a look at the
SoftwareGuide section 5.4.3, pdf pages
108-110.

Please let us know if you have further
questions,


Thanks


Luis


BTW, It is a nice idea to post
descriptive images as you just did.

I need these holes to somehow filled (not necessarily all holes, small ones would be enough. not necessarily very accurately,a rough method would be sufficient) so that that the object looks something like the right object.
