Abstract:

In order to solve the problem of visual fatigue induced by parallax change discontinuity, a method of adjusting uncomfortable frame is proposed. Based on the comfort evaluation model, the motion and disparity vectors of the current frame derived from the JMVC(Joint Multi-view Video Coding) multi-viewing coding system are applied to find the video frame which can cause visual fatigue, and such frame is further adjusted using disparity adjustment of a uncomfortable frame to get a new frame which can enhance the visual comfort for eyes. Viewers make subjective scores according to their physical symptoms and fatigue response. According to comparisons before and after adjustment, the results show that the comfort level using the proposed method increases by 5.13% than prior through parallax adjustment for uncomfortable frames. The proposed method improves the comfort of viewing stereoscopic video, guaranteeing the quality of video.
