Method for evaluating vision comfort of three-dimensional video based on brightness compensation

Abstract

The invention relates to a method for evaluating vision comfort of a three-dimensional video based on brightness compensation, which belongs to the technical field of three-dimensional video vision comfort. The method is characterized by comprising the following steps: extracting a foreground area of a three-dimensional video frame according to a gray-scale map of a left view and a right view of the three-dimensional video frame, synthesizing a disparity map, extracting horizontal disparity, and calculating depth disparity; establishing a disparity depth-vision comfort model according to a subjective evaluation result, optimizing the evaluation model of the vision comfort according to the brightness, so that the scoring of the model is closer to that of the human vision system; solving a coefficient determining model of the model by utilizing a reverse substitution method according to the human subjective evaluation and experiment result, and finally realizing the evaluation on the vision comfort of the three-dimensional video based on the characteristics of the human vision system. According to the brightness compensation method, the evaluation model of the vision comfort is optimized, and a three-dimensional video comfort evaluation model which is better adaptive to the human subjective sensing result is established, so that the model scoring is closer to the subjective experiment scoring of the human vision system characteristics.

Description

technical field [0001] The invention belongs to the technical field of visual comfort evaluation of stereoscopic video, and in particular relates to a method for evaluating visual comfort of stereoscopic video by using a brightness compensation method based on the characteristics of the human visual system. Background technique [0002] With the rapid development of multimedia technology and Internet technology, 3D stereoscopic video technology is constantly becoming mature. Compared with traditional ordinary video, it can clearly reproduce the scene information of the objective world, highlighting the layering of the scene and the vividness of the scene. Authenticity enables the audience to obtain a stronger sense of presence and visual impact, and more and more 3D video applications are changing our lives. At the end of 2010, the Asian Games opened in Guangzhou realized the broadcast of 3D signals, making people watching in front of the TV as if they had come to the scene ...

Problems solved by technology

At present, there is no unified judgment standard for the evaluation of the visual comfort of stereoscopic images. Therefore, it is of great significance to study the factors affecting the comfort of stereoscopic images / video content. How to establish an objective evaluation model of stereoscopic image quality that conforms to the results of human perception also appears to be particularly important
