I have a set of array as like below it is (x,y,w,h) how can I select the right array for me, here is the right array is number 3 which is have big (w) and big (h) then others. Actually it is a object detection from a image and (x,y,w,h) is the coordinates of the objects but I want my right objects which value have large (w) and large (h) on other hand can say that w/h=very close to 1 or h/w=very close to 1. I wanted to select that array for further actions.
