Hi Ashvin, thanks for your reply. But I am trying to trace the intensity profile of an image to locate the region of my interest(which is the vertebrae). How do I write a function to locate the zero clusters of the profile to mark the point.

Assuming you are looking for pixels with intensity, 128;

I = imread(img);

ind = find(I==128);

I(ind)=255;
