Abstract:

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.

Key words: stereoscopic video, comfort, salient region extracting, binocular disparity, evaluation, contrast
