【摘要】 立体图像质量评价是感知与显示的基础,也是立体视频系统设计的依据。由于图像的最终接受者是人,所以评价图像质量的关键在于其是否符合人类视觉系统特性。在分析视觉非线性、对比敏感度、多通道结构等人类视觉特性的基础上,提出了一种立体图像质量评价方法。该方法首先对图像进行5级小波分解,将图像的空间频率按视觉系统的掩盖效应特点分成6个频带分别进行滤波,以改变原始图像的空间频率。实验结果表明,所提出的方法优于传统的客观质量评价方法,能够反映图像的质量以及立体感。更多还原

【Abstract】 Stereo image quality assessment is the basement of perception and display and also the foundation of stereo video system design.Since human being is final receiver of the image,the key point of the image assessment is that it should match the characteristics of human visual system(HVS).A algorithm for stereo image quality assessment is proposed based on the basic HVS characteristics such as visual non-linearity,contrast sensitivity,multi-channel model and so on.Image are firstly performed five level wavelet decomposition,the spatial frequency of image is divided into six bands to vary spatial frequency of the initial image according to the characteristic of masking effect.The experimental results show that the proposed algorithm outperforms conventional objective image quality methods and reflect the image quality and stereo sense.更多还原
