How to save part of an image?

[EDN Admin]

Let say i have an image of a face. And i have detected the eyes with a rectangle around it, next i wish to save the eyes(only) that appear in the rectangle into a folder. How can i do it? Any suggestion?

This is the code where the eyes are detected and where the rectangles are drawn:
