image-dupe

Takes between two and eight images by URL or inline base64 and compares each pair.

Takes between two and eight images by URL or inline base64 and compares each pair. Three perceptual hashes are computed, because each fails differently: an average hash over an 8x8 grey image is cheap but moves with brightness, a gradient hash reads the slope between neighbouring pixels and survives exposure changes, and a DCT hash over the low frequencies of a 32x32 grey image is the sturdiest against rescaling and re-encoding.
