Interpolation of a gray scale image in matlab [closed]

Question

Gray Scale Image with Empty Black area

I want to fill the black areas with the value of neighboring pixels. Kind of interpolation. Can any one suggest me how Can I do in matlab.

This is technically on-topic, but it's an exact duplicate of a question on SO that already has a better answer (by the same user), so I'm closing it here. It's also a little more oriented towards MATLAB programming than DSP concepts, so it's only borderline on-topic.

	imfill fills with only one color. please suggest some other methods – crack_addict Jul 5 '12 at 5:23
	Then to fill one black area, try to identify a sub-region containing the black area first, then creates a Delaunay triangulation of the non-black points in inside the sub-region. It will allow you to do the interpolation at the black points. – chaohuang Jul 5 '12 at 5:33
	please explain in detail about what to do after I create the Delaunay Triangulation of non-black points. I can Identify the sub-Regions containing black area – crack_addict Jul 5 '12 at 5:37
	see my answer on stackoverflow – chaohuang Jul 5 '12 at 6:00
