摘要

立体图像观看舒适度的影响因素是立体成像技术领域的关键问题。结合视觉注意机制特性,定量研究饱和度因素对立体图像视觉舒适度的影响。首先,得到立体显著度图,利用模糊隶属度原理和掩膜对其进行优化获得最终的显著立体图像,并用眼动仪对所得立体图像显著区域的正确性进行验证。然后,采用改进的逐级逼近法进行主观实验,通过大量的实验数据得到显著立体图像的舒适饱和度匹配图和差异图。实验结果表明,双目视图舒适饱和度平均差异值最大可达0.29。验证实验表明所提方法的舒适饱和度范围具有更好的普适性,不仅为立体图像舒适度的研究提供了依据,而且为立体内容的制作提供了技术标准。

Abstract

The influencing factors of the viewing comfort of the stereo images is the key issue in the stereo imaging technology field. Combined with the characteristics of the visual attention mechanism, the influence of saturation factor on visual comfort of stereo image is quantitatively studied in this paper. Firstly, the stereo salient degree map is obtained, after that the fuzzy membership principle and the mask processor are put on it to get the final salient stereo image, and the eye tracker is used to verify the correctness of the salient area of the obtained stereo image. Then the subjective experiments are carried out with improved gradual approximation method, and the matching map and difference map of the comfortable saturation of the salient stereo image are obtained through a large number of experimental data. The experimental results show that the maximum average difference value of the comfortable saturation of the binocular view is 0.29. The verifying experiment shows the comfortable saturation ranges with the proposed method have a good universality. This work not only provides a basis for the study of stereo image comfort, but also provides technical standards for the making of stereo content.
