摘　　要：相同的前景图像在不同亮度的背景图像下,给人眼的视觉感受不相同,这是亮度掩盖效应的特性。依据韦勃-费赫涅耳定律,给出了亮度掩盖阈值的测量方法和结果,提出了一种基于亮度掩盖效应的图像质量评价模型。实验选用了不同的背景图像来考察亮度掩盖对图像质量的影响,与传统的客观评价模型相比,基于亮度掩盖的图像质量评价模型与人眼主观感受的吻合度更高。It was verified through experiments that the same foreground image gives different visual perception to human eyes under the background images with different brightness.That is the characteristic of brightness masking effect.According to Weber-Fechner law,the measurement methods and results of luminance masking threshold were given,and an image quality evaluation model based on luminance masking effect was proposed.Different background images were selected to investigate the impact of luminance masking on image quality.The experimental results show that compared with the traditional objective evaluation model,the image quality evaluation model based on luminance masking is more consistent with the subjective perception of human eyes.
