Please check this image. Is it possible to count the number of drops present?

I can't see the image. Are you sure the link is correct? In general, to find circles, use imfindcircle(). There is a demo in the help:
Measuring the Radius of a Roll of Tape
This example shows how to measure the radius of a roll of tape, which is partially obscured by the tape dispenser. Utilize imfindcircles to accomplish this task

Can you also supply me with your imfindcircle() code so I can run it? Since you're a MATLAB instructor developing a course for your students, why not just use the demos already in MATLAB to illustrate the concepts to your students? Why develop new ones, or ask us to?
