Abstract
An encoder including data processing arrangement configured to analyze depth information pertaining to input image to identify depth edge(s) and to determine location of depth edge(s); analyze input image to identify edges of objects and to determine locations of said edges; select, amongst edges in input image, matching edge(s) whose location matches with location of depth edge(s); obtain intermediate decoded image by decoding intermediate encoded image obtained from intermediate encoding of input image; analyze intermediate decoded image to identify edges of objects and to determine locations of said edges; determine edge(s) in intermediate decoded image that corresponds to matching edge(s); modify pixel values in input image and/or optical depths in depth information, based on difference in location of determined edge(s) in intermediate decoded image and location of matching edge(s); and encode input image and depth information, upon said modification, to generate encoded data.
