Definitely very low resolution, but compared to sites that use a solid color this seems much better. And only requiring one variable is really nice.
The article seems very well thought through. Though for both the algorithm and the benchmark algorithm the half blue / half green image with the lake shows the limitations of this technique. Still pretty good considering how light weight it is.
I did deliberately pick some "bad" examples like the blue+green image, and other multicolor images.
I wanted to add an upload function so people could test any image, then i realised I'd have to implement the compression/hashing in the client. Maybe i should!
