Abstract: Disclosed are methods and devices for coding and decoding depth information, which relate to a Three-Dimensional Video (3DV) coding technology. The coding method includes: arranging all elements in a DLT in an ascending order of values, wherein the DLT is a data structure representing depth numerical values by index numbers; coding a value of a first element in the DLT, and writing the bits of the value into a bitstream; and coding a difference value between a value of each of the other elements except the first element in the DLT and a value of an element with an index number smaller than an index number of the each of other elements in the DLT respectively, and writing the value of the difference value into the bitstream. The method for decoding depth information and related coding and decoding devices are also provided. By the technical solutions of the disclosure, efficiency of coding and decoding depth information is improved, and resource occupation during depth information coding is reduced.

Abstract: A coding method applied to HEVC-based 3DVC is provided in the example of the present document, which includes: in the HEVC-based 3DVC, before a parent prediction unit (PU) corresponding to a coding unit (CU) of a depth image is predicted, judging whether the parent PU meets a preset condition, if the parent PU meets the preset condition, evaluating only traditional intra modes of high efficiency video coding (HEVC) when the parent PU is coded, and if the parent PU does not meet the preset condition, evaluating the traditional intra modes of the HEVC and depth modeling modes (DMM) predictions when the parent PU is coded. A coding device applied to HEVC-based 3DVC is also provided in the example of the present document. In the example of the present document, by reducing the evaluated prediction modes, a coding speed is increased.
