Hello,
I have already obtained the reference point which is inside the circle as shown in the first picture labelled(d) below. From there, how do I trace along the boundary of the image as per the direction indicated by the arrow in picture(d) such that I obtain the graph as per picture (g) which is distance versus index of boundary pixels. Thank You.

Did you try bwtraceboundary()?

bwtraceboundary should not be in a loop. It gets all the boundary pixels in one shot. If I were you though, I'd use bwboundaries() since it does not require you to specify a starting location and starting direction. As long as you don't care about that (most people don't), it's easier.
