Method for error concealment of whole frame loss of stereoscopic video

Abstract

The invention discloses a method for error concealment of whole frame loss of stereoscopic video, which considers coding characteristics of the stereoscopic video sequence as well as similarities of the video sequence time domain and the inter-view video image information zone characteristics, estimates static zones and motion zones of a lost frame through image frames which are correctly decoded at a left view point and a right view point by using similarities between static zones and motion zones of images at the left view point and the right view point and static zones and motion zones of images of adjacent time at the same view point if the frame at the right view point for a time is lost, then uses inter-view global disparities to divide motion zones of the lost frame into a shielding boundary zone and a non-shielding boundary zone, restore lost information by respectively using motion compensation prediction and disparity compensation prediction for the shielding boundary zone and the non-shielding boundary zone, and directly uses a frame copying method to restore lost information for static zones. According to the method, the subjective quality and the objective quality of the stereoscopic video images can be effectively improved on the condition of whole frame loss at the right view point.

Description

technical field [0001] The invention relates to a video error concealment method, in particular to a stereoscopic video full frame loss error concealment method. Background technique [0002] With the rapid development of multimedia and network technology, video technology is developing in the direction of three-dimensional, digital, networked and high-definition. Compared with traditional media, the outstanding advantage of stereoscopic video is that it can create a more intuitive and real scene experience for the public, and provide more diversified and comprehensive media interaction functions. Therefore, people's demand for the development and application of stereoscopic video systems is becoming more and more urgent, such as in digital stereoscopic television, distance education, remote industrial control, 3D video conferencing systems, virtual reality systems, telemedicine, remote control robots, automatic navigation, consumer Electronics and many other fields.

Problems solved by technology

However, the existing error concealment methods for the whole frame loss of stereoscopic video cannot well consider the temporal correlation of different regions and the strength of the correlation between viewpoints, resulting in inaccurate prediction and affecting the restoration quality of damaged blocks.
