An interesting method to spot forged artworks -

The approach, known as "sparse coding", builds a virtual library of
an artist's works and breaks them down into the simplest possible
visual elements.
Verifiable works by that artist can be rebuilt
using varying proportions of those simple elements, while imitators'
works cannot.

There's some links to the right about some art forgery cases involving Frida Kahlo and J. Pollock.

Very interesting article Callie. First time I had time today to read it. Makes me wonder how reliable a system it is because I would think that artists styles aren't always that predictable from one painting to the next or maybe that's just me. Smile

I was thinking it's pretty amazing what computers can do, but it's even more amazing to me that some human thought this up.
I guess all our paintings have their own sort of "fingerprints" that make them unique.

I remember an art teacher telling me that our lines in drawing are as unique as a signature and that no 2 drawings will be exactly the same. That must be how it works like you said like a fingerprint.
