Embodiment Construction

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. 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.

[0020] The object of the present invention is to address the deficiencies in the prior art, propose a binocular perception-based fast encoding method for multi-viewpoint video, and determine the threshold for early termination of multi-reference frame search to realize fast encoding for multi-viewpoint video. In the case of ensuring a small coding rate distortion, it provides the best coding efficiency and significantly improves the multi-view video coding speed.

Abstract

The invention discloses a video coding method which comprises the following steps of judging whether a current coded sequence is a right viewpoint image or not, dividing the right viewpoint image into 16*16 pieces, judging whether a BJND value of a current macro block (i) of a current frame is larger than a threshold value T2 or not, judging whether the BJND value of the current macro block (i) of the current frame is larger than a threshold value T1 or not, judging whether the current macro block (i) is the last macro block of the current frame or not, and judging whether the current frame is the last frame of a right viewpoint or not. By the implementation of the video coding method, complexity of coding is lowered remarkably. The video coding method further improves the real time performance in remote communications of stereoscopic videos, and plays a certain role in practical application of the stereoscopic videos.

Description

technical field [0001] The invention relates to the technical field of audio and video coding, in particular to a video coding method. Background technique [0002] Entering the information age, computer, communication and display technologies have developed rapidly. After decades of development and application, analog TV is now being replaced by digital TV. High-definition TV further improves visual authenticity by increasing the resolution of image display. However, the 2D digital TV technology described by plane images is far from meeting people's increasing demands for more realistic and natural scene reproduction. In the future, digital video will develop in the direction of improving visual reality, interactivity and modeling, and 3D TV will replace high-definition TV and become the mainstream of next-generation digital video technology. Three-dimensional TV is a TV system that uses the principle of human visual characteristics to realize people's three-dimensional p...
