I would like to know how to divide this array R1=R(70:194,10:224) into two equal halves? I want to know the central coordinate. for that should i calculate the distance between the two extremes and then calculate mean? If yes, then how to calculate the distance between the co ordinates?

That's not usually what it means to segment an image. See http://en.wikipedia.org/wiki/Image_segmentation

Josephine, the matrix is a 125-by-215 (row-by-column)
size(R1)
ans =
125 215
therefore, you can't evenly split it into two halves. The center row and column are #62 and #107, if that helps at all.

But actually 63 and 108 are the centers - think again and you'll see why. 63 has 62 on one side, 62 on the other side, and then include the central row and you get 125. So you should use ceil() and not floor().
