基于可控金字塔的立体图像质量评价方法

摘要

在分析和模拟人眼感知立体图像方式的基础上,提出了一种评价立体图像质量的方法.该方法结合人眼视觉特征和结构相似度算法对立体图像质量进行评价,利用可控金字塔模拟人眼视觉特性中的多通道效应,同时采用立体图像左右视图的特征点的匹配算法对立体图像的立体感进行评价.实验结果表明,该方法与主观评价结果基本一致,能够更好地反映立体图像质量及立体感.%Through analyzing and simulating human visual perception of stereo image, an objective quality evaluation method of stereo image was proposed. The method combined the characteristics of Human Visual System ( HVS) with Structural Similarity, using steerable pyramid to simulate multi-channel effects. Meanwhile, the proposed method used stereo matching algorithm to assess the stereo sense. The experimental results show that the proposed objective method achieves consistent stereoscopic image quality evaluation result with subjective assessment and can better reflect the level of image quality and stereo sense.
