Depth image coding algorithm via the colorization based image coding

Abstract

This paper proposes a depth image coding algorithm derived from the colorization based image coding algorithm. In the colorization based image coding algorithm, the chrominance images are coded using the luminance image, and high coding performance is achieved. Motivated by this algorithm, this paper proposes a new RGB image guided depth image coding algorithm. This paper assumes that the RGB image corresponding to the depth image is given, and the depth image is encoded and decoded using the RGB image. The numerical examples show that the proposed algorithm achieves a high compression performance compared with JPEG coding and JPEG2000 coding.
