立体QoE视频库构建
|
摘要
由于立体视频左右视点之间存在视差,因此立体视频能为观看者提供深度信息,给观众带来身临其境的视觉体验。但另一方面,立体视频比较容易导致视觉疲劳影响主观舒适度。因此,准确有效进行立体视频QoE评价具有很重要的意义。本文构建了一个立体QoE视频库,该视频库的主观不舒适度分值可反映视频序列的主观舒适度,可被用于视觉舒适度评估技术的研究。另外,我们对立体视频库的视差、运动、纹理进行了分析。
Because of the disparity of stereo video between left and right viewpoints,stereo videos can provide viewers with depth and gives the viewera visual experience.On the other hand,stereoscopic videomay cause visual fatigue to effects of subjective comfort easily.Therefore,it has a great significance to evaluate the stereo video quality of experience effectively.This paper presents a comprehensive stereo video database,the subjective discomfort score of this database can reflect the subjective comfort of the video sequence.That can be used to design a new visual comfort prediction technique.In addition,we analyze the database with respect to disparity,motion and texture.
