Was going through the series and thought this was an interesting use of FDI for detecting forgeries in comic art. Thought it would interest some science based viewers here.

WTF Is FDI fractional dimensional index?

 

It's a measure of jaggedness of a perimeter, related to a guy named Mandelbrot (and Hurst).

If you measure a coastline, with different resolutions, you get different results, depending on the how precise the measurement instrument. They can use that technology to measure approximate edge lengths in art strokes, and compare to forgeries (in this case).

Hah. they used Will Wheaton for this.
