I'd also like to know another 100 Point approach for Artclass :)
My friend had a ten-line 100p solution. I was stunned!
How? Teach me master :D
It goes something like this:
Turn the image to grayscale, calculate the average of absolute differences of values for all adjacent pixel pairs. You can experiment with images given to find appropriate bounds of this value for each class. After you did that, you code them as four if-s. It turns out this works around 91% of the time, of course, scoring 100p. Amazingly simple.
