COLOR DEMOSAICKING USING DIRECTION SIMILARITY IN COLOR DIFFERENCE SPACES

摘要

Demosaicking optimizations are provided for still and/or moving image (e.g., video) processes that efficiently generate viewable images. A demosaicking process selects a direction before performing interpolation in order to avoid interpolation across edges and also to minimize color artifacts. The direction to be selected is based on a direction similarity measurement. A digital capture device can includes a system that processes the image data by performing interpolation based on the direction similarity measurement(s) for color difference spaces. The images created based on the directional similarities demonstrate performance gains in peak signal to noise ratio (PSNR).
