摘要:An adaptive demosaicing method is disclosed that interpolates images based oncolor edge detection and neighborhood voting. The adaptive demosaicing algorithm usesa voting scheme to determine the direction of interpolation at each missing luminancepixel location. Each color plane votes either horizontal or vertical based on a comparisonbetween the vertical and horizontal components of the degree of change (i.e., gradient,Laplacian or other measure of the degree of change) in that color plane. Votes arecounted from the neighborhood pixels as well as from measurements taken at the pixellocation itself. Once the luminance plane is fully interpolated, the chrominance planes arefilled in by a simple bilinear or median interpolation of difference chrominance values.Enhancements to the adaptive demosaicing algorithm permit adaptive smoothing andsharpening.
