基于对比度补偿的立体视频舒适度评价

Evaluation of Stereoscopic Video Comfort Based on Contrast Compensation

为给评价立体视频的舒适程度提供一种可参考的标准,在确定人眼观看立体视频时水平视差为主要影响因素基础上,以对比度作为其补偿因素对立体视频舒适度的影响。利用图形分割方法将前景与背景分离,利用场景相关的显著区域提取方法得到显著区域,提取显著区域的视差并分别提取前景和背景对比度,结合深度感知理论和最小二乘拟合方法建立评价模型,利用主观评价方法对模型进行评定,由此得到对立体视频舒适度评价的一种方法。由主观评价验证可知,该评价方法与人眼的立体视觉基本一致,为进一步研究人眼立体舒适度提供参考。

In order to evaluate the comfort level of stereoscopic video, to provide some reference research material for the experts to study. Refer the parallax as the main influencing factors when human are viewing stereoscopic video and make the contrast as compensation for evaluating stereoscopic video comfort. Firstly, graphic segmentation method is used to separate foreground and background, scenes related significant regions extraction method is used to extract the salient region, the salient region parallax and the contrast from the foreground and background, and combining with depth perception and least square fitting method to establish evaluation model. Finally, the subjective evaluation methods are used to evaluate the model, hereby a method for three-dimensional video comfort evaluation is got. Evaluation shows that this method is basically the same as stereoscopic vision of the human eye, providing comfort considerations for further study on the human eye viewing stereoscopic.
