How to differenciate Image Object based on Object properties ?

How to differenciate Image Object based on Object properties ? can share any one idea's?

Differentiate implies that there is more than one object, yet you showed us only 1.

Maybe the other one is a gray scale image and all you have to do is to count the gray levels in each one. Maybe the other one has concentric squares and we need to determine shape. Maybe one has several big circles and the other has one small circle so maybe you need to count the circles and get their areas. I have no idea because you forgot to post any other images.
