Search similitary of a picture in folder of thousand others

[wilbert]

What I'm trying to do is find greyscale images that are similar to a colour 'master image'.

Try this module

Compute the YIQhash from both images using the ImageHash or FileHash procedure.
To compare, use the HammingDistance(Hash1.q, Hash2.q) procedure and from both hashes, pass only the Y channel YIQhash\Y .
That should give the result you want (a low hamming distance value for similar images).

Sounds interesting wilbert - inspired by streaky bacon?

Works well - a side benefit is that it also gets tif image similarity correct.
