if manually marking selected leaves is an option, the 'watershed' method might work nicely:

note, that it is not enough to mark the selected leaves, you will have to mark their neighbours as well to get the borders right.

Thanks. How can i segment the leaf without manual marking?. i.e I have to write a program in OpenCV whose input is the image above. I am going to consider three points in the image in programming. In that three, if leaf is present it must be detected and segmented.

in some case the size of leaf may be large at that time two or three points may reside on one leaf. That leaf has to segmented.

Tells me steps involved in it.

Thanks Mr.BeraK
