Abstract

A method for compressing a depth image including a matrix of pixels, each pixel including a pixel depth value, includes dividing the depth image into a plurality of non-overlapping tiles. Each of the plurality of non-overlapping tiles includes a contiguous subset of pixels. For each of the plurality of non-overlapping tiles, the pixel depth values are quantized into quantized pixel depth values. For each of the plurality of non-overlapping tiles, the quantized pixel depth values are encoded into a compressed depth image.
