Color filter array color reproduction using cycle-spinning

Abstract Color filter array (CFA) color reproduction aims to produce an image with full color information from its CFA counterpart. Conventional subband synthesis based color reproduction technique utilizes the decimated wavelet transform, which is not shift-invariant and could result in ringing artifacts in the resulting color image. To alleviate these artifacts, the cycle-spinning (CS) technique is introduced in this Letter to perform CFA color reproduction. Experiments are conducted to demonstrate the superior performance of the proposed approach.
