A Computational Darkroom for Black-and-White Photography Soonmin Bae, Sylvain Paris, and Frédo Durand MIT CSAIL Enhancement of black-and-white photographs “Look” transfer between two images Direct interpolation and manipulation of the “look”

Approaches Global contrast Decomposition of an image into large-scale variation layer and high frequency texture layer Control the global contrast and the local textureness separately Quantitative characterization Use image statistics and histograms input Local textureness

Direct Manipulation
