Abstract:
A digital image system for processing a demosaiced digital image to reduce color aliasing artifacts, said demosaiced image including color planes, said system comprising:a wavelet transformer for computing a respective wavelet transform of each of said color planes of said demosaiced digital image, each said wavelet transform including an approximation signal and detail signals; for each of said color planes, a set of inverse wavelet transformers for computing first detail inverse wavelet transforms using said approximation signal of an associated one of said color planes of said respective set of inverse wavelet transformers and said detail signals of a first different one of said color planes, second detail inverse wavelet transforms using said approximation signal of said associated color plane and said detail signals of a second different one of said color planes and approximation inverse wavelet transforms using said approximation signal and said detail signals of said associated color plane; and for each of said color planes, a combiner connected to said respective set of inverse wavelet transformers for combining each said approximation inverse wavelet transforms with said respective first and second detail inverse wavelet transforms to produce correlated color planes of said color planes.
