METHOD, APPARATUS AND COMPUTER PROGRAM PRODUCT FOR REDUCING CHROMATIC ABERRATIONS IN DECONVOLVED IMAGES

摘要

In an example embodiment, method, apparatus and computer program product are provided. The method includes facilitating receipt of a deconvolved image including a plurality of component images. A guide image is selected from the component images and a cross-filtering is performed of component images other than the guide image to generate filtered component images. The cross-filtering is performed of a component image by iteratively performing, selecting a pixel and a set of neighboring pixels around the pixel in the guide image, computing a set of weights corresponding to the set of neighboring pixels based at least on spatial differences between the pixel and the set of neighboring pixels, and cross-filtering a corresponding pixel of the pixel in the component image based on the set of weights to generate a filtered corresponding pixel in the component image. The filtered component images form a filtered deconvolved image with reduced chromatic aberration.

1. A method comprising:
facilitating receipt of a deconvolved image, the deconvolved image comprising a plurality of component images corresponding to a plurality of image channels; selecting a guide image from among the plurality of component images; and performing a cross-filtering of one or more component images that are other than the guide image in the plurality of component images to generate one or more filtered component images, wherein performing the cross-filtering comprises iteratively performing:
selecting a pixel and a set of neighboring pixels around the pixel in the guide image;computing a set of weights corresponding to the set of neighboring pixels based at least on spatial differences between the pixel and the set of neighboring pixels; andfiltering a corresponding pixel of the pixel in the component image based on the set of weights to generate a filtered corresponding pixel, wherein the one or more filtered component images form a filtered deconvolved image with a reduced chromatic aberration.
