Problems solved by technology

However, the existing full frame loss error concealment method does not fully consider the subjective perception of the human eye, so the recovery effect is not ideal, and further improvement is still needed

Embodiment Construction

[0044] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0045]The present invention proposes a method for concealing errors based on structural similarity of the whole frame loss of stereoscopic video, and its overall realization block diagram is as follows: figure 1 As shown, it includes the following steps:

[0046] ① Stereoscopic video is divided into two viewpoints, left viewpoint and right viewpoint, assuming the right viewpoint s of stereoscopic video R The image frame at time t is the missing frame, and it is recorded as Then: the right viewpoint s of the stereoscopic video R The image frame at time t-1 in the time domain direction that has been correctly decoded is denoted as The right view point s of the stereoscopic video R The image frame at time t-2 in the time domain direction that has been correctly decoded is denoted as Set the left view point s of the stereoscopic video L c...

Abstract

The invention discloses a stereoscopic video whole frame loss error hiding method based on structural similarity. The stereoscopic video whole frame loss error hiding method based on the structural similarity is effectively combined with subjective perceptions from human eyes to picture structure information, respectively uses a motion compensation forecasting method or a parallax compensation forecasting method to recover errors aiming at different macro block reference modes of macro blocks in a dropped frame by judging the macro block reference modes of reference image frames of a moment before the dropped frame, and further is intensively combined with the subjective perceptions from the human eyes to picture structure similarity due to the fact that time domain pertinence and pertinences among viewpoints of traditional stereoscopic video are fully considered, and therefore not only objective quality of recovering of the dropped frame can be improved, but also subjective quality of the recovering of the dropped frame can be enabled to be close to the perceptions of the human eyes.

Description

technical field [0001] The invention relates to a stereoscopic video error concealment method, in particular to a stereoscopic video whole frame loss error concealment method based on structural similarity. Background technique [0002] Stereoscopic video technology, as a new multimedia technology, is used to capture real world scenes, attracting more and more attention, and can be widely used in medicine, military, family and so on. Compared with single-viewpoint video, stereoscopic video needs to transmit more data volume, so it must be effectively compressed by using an efficient compression coding method. At present, stereoscopic video compression coding methods generally use time and space correlation prediction to reduce redundant information in the time domain, space domain and viewpoint domain, which makes the video stream less resistant to channel errors and more sensitive to channel distortion. In the process of encoding and transmission, due to channel noise and ...
