Cropping always involves cutting away part of the original image and results in some of the pixels being discarded.

How do you find the similarity between images?

Mathematically, we represent a similarity measure between two images A and B as S(A,B) = D(T(A),T(B)) . The following example illustrates the use of a similarity measure in a content-based image retrieval (CBIR) system.
