Design and Evaluation of Demosaicing Algorithms for RGBW CFA
Introduction
Engineering in the commercial imaging sector knows nothing of patience; if anything, the pace at which camera technology is growing is faster than ever. Improvements are being made at an incredible pace across the entire range of the imaging system. One aspect that has not seen this pace, however, is one that has seen itself roughly constant since its introduction forty years ago, in 1976: the Bayer color filter array.
Color filter arrays represent a key .. blahblahblah ***TODO: finish, say more.

Image capture
Working with a prototype proprietary imaging sensor imposes certain restrictions on usability. Concretely, all management of imaging parameters must be manually controlled from an external computer via a USB link. The company, OmniVision, provided a software package, OVTAPanther, to mediate this process.
