Original intensity + gradient map




Increased intensity (1.5 times) + ETF

Mainly based on the quality of the ETF edges.But it looks better. It might go to the Minimal artistic rendering paper since theirs is based on tone balance.


Black and white (original intensity + ETF)

Only based on the error to determine the color (black or white) in a raster scanning order. The problem is because in the dark area the etf edges should be white. But right now it is not. And another factor is that the error is not diffused now.
