摘要：
A normalized color-ratio model suitable for color filter array (CFA) interpolation schemes in single-sensor imaging devices is introduced. The first proposed solution utilizes linear shifting of the CFA inputs, whereas the second design uses both scaling and shifting operations to normalize color components appearing in the CFA interpolator's input. The utilization of the proposed models can significantly boost the performance of most well-known CFA interpolators. Experimental results indicate that the CFA solutions employing the proposed models exhibit superior performance and eliminates color moire, aliasing and color shifts in the full color camera output.
