Our work in this area includes statistical estimation for color management, Bayer filter de-mosaicking for digital cameras, and a portfolio of work in color halftoning including a number of pending patents. Recent work focuses on regularized local linear regression over adaptively-sized neighborhoods to learn ICC profiles for color management, custom color enhancements, and gamut expansion.
