What is the result of imellipse() that "doesnt result well"? What are you doing with it's roi returned variable, and why is that returned variable no good?

because the shape is not exactly ellipse and the adjacent shapes are included in the ellips that are not allowed.
the image attached is the desired croped which i have done in with imfreehand.

For code you are requested to contact me through author page

The code belongs to me and this ongoing work is not published yet, when it will get published I will upload it here.
