How are you storing the values of multiple Rectangles & how you are drawing them? – Balaji R Sep 19 '14 at 06:46
iam using [y:y+h,x:x+w], i drawing them with cv2.rectangle().all i want that all cropped ROI's that i save have name in order like ex : a-z etc. you can see in the "similiar code" – user3794777 Sep 20 '14 at 09:50
i mean how are you looping through all the rectangles stored? – Balaji R Sep 22 '14 at 05:16
