Embodiment Construction

[0029] In this patent specification and claims, certain words are used to refer to specific components. Those with ordinary knowledge in the field should understand that hardware manufacturers may use different terms to refer to the same component. This patent specification and claims do not use differences in names as a way to distinguish components, but use differences in functions of components as a criterion. The "include" or "include" mentioned in the entire specification and the claims are open-ended terms, so they should be interpreted as "include but not limited to". In addition, the term "coupled" herein includes any direct and indirect electrical connection means. Therefore, if the text describes that a first device is coupled to a second device, it means that the first device can be directly electrically connected to the second device, or indirectly electrically connected to the second device through other devices or connecting means .

Abstract

The invention provides a depth-based block partition method used for multiple view encoding and decoding or three-dimensional video encoding and decoding. The depth-based block partition method includes steps of receiving input data related to texture in a dependent view; determining corresponding depth blocks or reference texture blocks for the current texture block in a reference view; obtaining uniform representative values based on the corresponding depth blocks or reference texture blocks; generating current partition masks by adopting the uniform representative values according to the corresponding depth blocks or the reference texture blocks; selecting current block partition from candidate block partition based on the corresponding depth blocks or the reference texture blocks or the uniform representative values; and performing depth-based block partition or decoding on the current texture block. By utilizing the depth-based block partition method provided by the invention, computing complexity of coding and decoding can be reduced.

Description

Technical field [0001] The present invention relates to three-dimensional (3D) and multi-view (multi-view) video coding, and particularly relates to the use of depth-based block partitioning (Depth-Based Block Partitioning, DBBP) to improve the coding efficiency of texture (texture) )coding. Background technique [0002] In recent years, 3D television (television, TV) has become a technological trend, which can bring a very good viewing experience to viewers. Various technologies have been developed for 3D viewing, among which multi-view video is a key technology especially for 3DTV. Traditional video is a 2D media, which can only provide a single view of a scene from the viewer's camera angle. However, 3D video can provide any viewpoint of a dynamic scene and provide the viewer with a real feeling. [0003] 3D video is usually established by using a video camera to capture a scene and using related devices to capture depth information, or by using multiple cameras to capture a ...
