Problems solved by technology

[0005] However, the disadvantage of the above two video codecs is that the computational complexity of the decoding end is much greater than that of the encoding end. This extreme method makes the computational complexity of the decoding end far greater than that of the encoding end, and is not suitable for point-to-point communication.

Abstract

The invention discloses a complexity-balanced video coding method. The method comprises the following steps: the step 01) dividing original video sequences into K frames and W frames based on GOP; the step 02) for the K frames, utilizing an inframe coding method to perform coding; step 03) for the W frames, utilizing an LDPC to perform coding; and the step 04) for each frame of W frame, calculating corresponding offset amount, Laplace operator information entropy simultaneously. The invention discloses the decoding method of the video coding method simultaneously. According to the complexity-balanced video coding and decoding method in the invention, the operation for calculating the offset amount and the information entropy is transferred from the decoding end to the coding end, thereby reducing operation amount at the decoding end, and improving the operation amount at the coding end, and enabling the complexity at the coding end and the decoding end to be balanced.

Description

technical field [0001] The invention relates to the field of video coding, in particular to a complexity-balanced video coding method and a decoding method thereof. Background technique [0002] Video encoding refers to the method of converting a video format file into another video format file through a specific compression technology. Distributed Video Coding (Distributed Video Coding, DVC) is based on Slepian-Wolf theory and Wyner-Ziv theory, independently encodes two or more independent and identically distributed sources, and then a single decoder utilizes the information between sources Correlation jointly decodes all encoded sources. Theoretical research on distributed video coding began with the information theory established in the 1970s, that is, the distributed lossless coding theory established by Slepian-Wolf and the lossy coding theory using decoding side information (Side Information) established by Wyner-Ziv. The application of coding and decoding based on ...
