Abstract:
A method for image noise filtering is provided that includes receiving a Bayer domain image with four color channels, generating a hierarchical representation of the four color channels comprising a set of coefficient arrays at each level of the hierarchical representation, modifying the coefficient arrays of the color channels jointly to remove noise, and generating a noise filtered and edge enhanced Bayer domain image based on the jointly modified coefficient arrays.
