基于DWT和视觉加权的图像质量评价方法研究
摘要
提出了一种新的基于小波变换和视觉加权的图像质量客观评价方法(WVWPSNR
wavelet and vision weighted peak signal noise ratio)。该方法将图像的DWT和HVS特性相结合
A new objective method WVWPSNR(wavelet and vision weighted peak signal noise ratio) was presented.In which the method was based on DWT
and the sensitivity of HVS(human visual system) was weighted using sub-band division.In this method
the assessment valued of the new method accord with MOS(mean opinion score).In order to demonstrate the effectiveness and to verify the reliability of WVWPSNR method
a series of experiment for JPEG、JPEG2000、White Noise、Gaussian Blur and FastFading images were made and tested.The results suggest that the proposed method can provide accurate measures of image quality under JPEG compression.
