Example Embodiment

[0040] The present invention will be further described in detail below in conjunction with the accompanying drawings. The present invention will describe the following implementations in detail from two parts: the calibration of projection equipment parameters and the evaluation of stereoscopic video comfort.

[0041] 1. Calibration of projection equipment parameters

[0042] Due to the influence of different types of experimental equipment and experimental conditions, it is difficult to guarantee the accuracy of comfort evaluation when observing stereoscopic video. Therefore, it is necessary to calibrate the parameters of the projection equipment first. Here, the present invention compares the characteristic curves between various factors that affect the visual comfort rating (such as visual fatigue, physical discomfort, inattention) and the subjective evaluation experimental results through a human subjective evaluation, and establishes The visual comfort evaluation model i...

Abstract

The invention discloses a stereoscopic video visual comfort evaluation method based on region segmentation and belongs to the technical field of three-dimensional picture evaluation. The method comprises the steps of self-adaptively extracting motion areas in stereo video sequences and significant areas in background parts; combining depth sensing theory and space combination technology to conduct modeling on the characteristic quantity of visual comfort level; utilizing the linear regression method and combining the logic relationship between human being subjective evaluation testing results and the parallax depth to select undetermined coefficient and feature weighting value conforming to the human being subjective evaluation results and realize evaluation of stereoscopic video comfort adaptiveness. The method demarcates projection equipment and experimental conditions, respectively presets weight on a background part and a motion target in a significant region to realize optimization of evaluation results of comfort level, builds a stereo image quality objective evaluation model conforming to human subjective perception results, and has an immeasurable significant function in quickening the development of a stereo video system.

Description

technical field [0001] The invention belongs to the technical field of stereoscopic image evaluation, and in particular relates to a method for evaluating visual comfort of stereoscopic video based on region segmentation. Background technique [0002] With the vigorous development of multimedia technology and Internet technology, stereoscopic video technology is developing rapidly. Compared with traditional media, stereoscopic video can create a more intuitive and real scene experience for the public, and at the same time can obtain a stronger sense of presence. However, due to the imperfection of stereoscopic video technology, it also brings some adverse effects. [0003] Viewers often use the concept of visual comfort to reflect the degree of comfort they feel subjectively when watching stereoscopic images, which is specifically reflected in the degree of eye fatigue and physical reflection after watching stereoscopic images for a certain period of time. Different from f...
