摘要:
A method for coding multi-view video images is provided in the present invention. The method comprises: obtaining a view dependency between inter-view reference images for a viewpoint image; and encoding the viewpoint image in motion skip mode according to the view dependency and a first inter-view motion dependency of a first non-anchor image, wherein the first non-anchor image has no inter-view reference image. In the embodiments of the present invention, inter-view motion dependencies of the image under coding are set, and therefore, the coding and the decoding of the multi-view video images in motion skip mode are simplified, and the efficiency in and the gain of coding the multi-view video image are improved.
摘要:
A method and an apparatus of multi-view coding and decoding are provided. In the process of encoding multi-view video images, a frame number and view identifier information of the image that uses auxiliary reference information are written into a code stream, and sent to the decoder. The decoder obtains the frame number and the view identifier information of the image that uses the auxiliary reference information, and determines the auxiliary reference information applied to a specified image according to the frame number and the view identifier information. Errors of the image may be concealed according to the auxiliary reference information.
摘要:
A method, an apparatus and a system for a rapid motion search applied in template matching are disclosed. The method includes: selecting motion vectors of blocks related to a current block as candidate motion vectors of the current block; after the uniqueness of a series of the candidate motion vectors of the current block is maintained, calculating the cost function of the candidate motion vectors in a corresponding template area of a reference frame, and obtaining the motion vector of the best matching template from the candidate motion vectors of the current block. In the embodiments of the present invention, there is no need to determine a large search range and no need to determine the corresponding search path template, and it is only necessary to perform a search in a smaller range.
