Second mod note: the links are broken again[/color]

Hi, all

I have recently faced with an abstruse problem in image processing.

So, I would like to ask somebody's advice.

There are two images below; one is original and the other is an impaired original image.

I need to reconstruct the impaired original image as like the original, and also need to find out the center of gravity on the impaired image.

I have excogitated simple morphological processes such as dilation and erosion, but it was not enough.

Though this is a task to be solved by myself, I would like to share and discuss about this problem.

Can anybody give me a direction?
