Abstract
A method, an image processing apparatus, and computer program product for multilevel bilateral noise filtering of digital images are provided. The method includes receiving from an image sensor an image frame including a color mosaic having a color filter array (CFA) pattern, decomposing the image frame into at least one color plane image for each of a plurality of color planes, sequentially and separately reducing noise in the at least one color plane image by performing multilevel bilateral noise filtering of the at least one color plane image, and reconstructing the at least one color plane image to generate a noise filtered image frame.
