Is there possible to compare two images with different resolutions?
I mean here some algorithmic/programming approach. For instance, now I calculate hash code from image's byte array and compare these hash code values. That is work great but fail in case of different resolutions, i.e. images are identical by eye but different in it byte content.
For example see my image attaches:
one of it has 72 ppi but another 96 ppi. I would like to have TRUE value while comparing on equality but now I get FALSE. Help please to find correct solution here.
