Dear Siddha,

This could be a way to get your result:

1. Detect all the objects in the image. (<http://www.mathworks.com/discovery/object-detection.html website>)
2. Analyse each object if there is an infection.This could be done here.
3. Then you can construct an image with only the leaves that have an infection.

Good luck! Christiaan
