Thanks again for the new probable solution.

I have come up with another possible solution to solve this problem using ImageJ. But I have one more issue and if I get satisfactory result from it may be I can share it for future purpose.

So the situation is like this:
In a 8-bit image, pixel with 255 value (dark) are representing cracks in concrete. Now as a crack is a linear feature extending over some length, dark pixels are forming a linear shape. Does anybody know how to trim the corner pixels in such linear arrangement so that I can get to the middle pixel? I know I can do it visually but then it would not be accurate enough.

Please ask If you don't understand the fact. I am sharing the image so that you can understand more what I am trying to say.
