What do you mean by horizontal histogram? A histogram is the frequency of occurrence vs. gray level? Do you actually mean profile, which is the sum of all gray levels as a function of distance? If so

horizontalProfile = sum(grayImage, 1);   % Sum vertically to produce the horizontal profile.
verticalProfile = sum(grayImage, 2);     % Sum horizontally to produce the vertical profile.

What i mean can be understand by these images

Its a horizontal histogram,they produced it from blobs of the images when two objects overlap, i want to see the same histograms (vertical and horizontal) but for edges which is of two overlapping humans in image.

Horizontal histogram

I suggest you use something like watershed to break apart blobs that are known to be larger than expected.

But i want to break the edges.So what you suggest for that.

Why? If all you have are edges, for some reason, then fill them to create solid blobs, and then use watershed.
