Why not convert to HSB and build a function based on the hue &/or saturation channels, maybe first converting low brightness values to NaN?

Subject: differentiation of RGB images (sorting)

[EXTERNAL]

Hi,

I have some macro code, where I need to sort images based on their colour as some kind of quick 'classification'. I though about analysing some similar coloured images to get a 'descriptor' in form of softened ranges of RGB or Lab, but maybe exactly this is already there and I simply don't know where to look, like before :))

I tested the Color Inspector 3D, but this is more suited for visualization, although it provides some nice clustered representation.

Any hint would be great.

Kind regards,
Rainer
