Cubism from photographs


Non-photorealistic rendering from photographs most often uses “filters” that change a small image patch into a brush stroke. But making brush strokes can never transform a photograph into art that requires objects to change shape: cubism is an obvious example.

Our cubism project was the first to move away from using filters and towards image understanding. Three advances were necessary: (1) We defined pixel salience as global property - that is a pixel is important only when compared to all other pixels in the image; see Salient Painting. (2) We aggregated salient pixels into image regions to be used as painting primitives. (3) We composited a painting by cutting salient regions from many photographs.
