Hi folks.
Does anyone know a way of finding "100% exact image duplicates"
"exact image duplicates": means that each pixel in image A has the same colour as in image B
Note that images can be 100% identical but have different file size and hash value (e.g. think of .jpeg images with comments or added/deleted exif data).
I have tested several "image duplicate finder" programs, and while they work extremely well for finding similar images, none of them offers the possibility to check if images are exactly identical. Some of them even display a "similarity percentage value", but - alas - 100% does not really mean 100% identical, but rather "a very close match" (which sometimes turns out to be 100% identical, but sometimes not). Bad terminology.
I also have command line programs which can compare two images and tell me whether or not they are 100% identical. But they are not capable of comparing multiple images (one file against a file list, or all files within a file list, or one file list against another one).
So anyone knows how to find 100% exact image duplicates ?
thanks
