Title: METHOD AND APPARATUS FOR VIDEO DEPTH MAP CODING AND DECODING
Abstract:
A method for encoding at least one depth image frame within a sequence of depth image frames, the method comprising: segmenting each at least one depth image frame into an array of depth image blocks;determining for each depth image block a minimum depth image value and a maximum depth image value;generating a maximum depth image from the determined maximum depth image values;generating a minimum depth image from the determined minimum depth image values; and encoding values of the at least one depth image frame based on values of the maximum depth image and values of the minimum depth image at corresponding positions.
