基于亮度加权网络空间扩展的图像质量评价方法

An image quality assessment of spatial expansion method based on brightness weighted network

采用CCIR颁布的亮度加权网络时域频率标准,基于电视学基本原理和数字图像处理方法,将亮度加权网络由时域频率扩展到空间频率,由此建立一个实验平台考察图像空间尺寸对视觉感受的影响.该方法实验结果与视觉感知的图像质量评价结果吻合,其有效性取决于时域亮度加权网络主观实验结果.由于避开了主观评价实验的标准化苛刻要求,因此降低了多通道分解图像质量度量方法的复杂度,有利于图像空间尺寸的质量评价.

Based on the basic principles of Television and digital image processing technology, this paper established an experimental platform to explore the impact of the image space size with the visual perception by using brightness weighted network which was published by CCIR. Experiment results were in line with the visual perception of image quality evaluation results, and the validity of experiment results depended on subjective experiment results of brightness weighted network. The strict requirements of subjective evaluation experiment standardization were avoided, so complexity of the multi- channel decomposition image quality measurement method was reduced. In addition, the implement of this method was helpful for the measurement of multi-channel decomposition method.
