Embodiment Construction

[0260] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0261]Commonly used depth image coding includes depth modeling mode (DepthModelingMode, hereinafter referred to as DMM) and simplified depth coding mode (SimplifiedDepthCoding, hereinafter referred to as SDC). The pixels of the block are respectively made a difference to obtain the residual, and the residual is encoded. The simplified depth coding...

Abstract

An embodiment of the invention provides a method and a device for coding and decoding depth images. The method includes dividing a ninth numerical value by a number value of pixels in predicted data to obtain a mapping value; multiplying the mapping value by a sum value of pixel values of the pixels in the predicted data to obtain a first numerical value; shifting the first numerical value to obtain a second numerical value; acquiring residual errors of a current image block according to the second numerical value and pixel values of pixels of the current image block; and coding the residual errors of the current image block. The method and the device have the advantage that the implementation complexity of a coding procedure is only relevant to a value range of the number value of the pixels in the predicted data, and accordingly is decreased to a certain extent.

Description

technical field [0001] Embodiments of the present invention relate to image processing technologies, and in particular, to a codec method and a codec device for a depth image. Background technique [0002] The 3D video image system has been widely used because it includes two types of image information, the view image and the depth image, which makes the image visual effect good. [0003] In the prior art, the process of encoding and decoding three-dimensional video images is generally to obtain the prediction data of the image block to be encoded according to the intra prediction mode, and combine the pixel value and value of the pixel in the prediction data with the value of the number of pixels in the prediction data The average value of the pixels of the prediction data is obtained, and the difference between the average value of the pixels and the pixel value of the image block to be encoded is obtained to obtain the residual of the image block to be encoded, and the re...
