掩盖效应是HVS模型的一部分，基于掩盖效应的图像质量评价方法只考虑了标准图像的影响，忽略了误差图像本身的影响。依据掩盖模型和空间向量分解，文章提出了一种新的图像质量评价方法。该方法将误差图像分解得到对比度无关分量，与掩盖阈值比较，剔除低于掩盖阈值的部分。通过实验表明，该方法简单易行，从视觉感知和结构化2个方面对图像质量进行评测，比传统客观方法更贴近人眼主观感受。

Masking effect is part of the human visual system (HVS) .Image quality assessment based on masking method only considers the effect of image annotation and ignores the effect of error in the im‐age itself .Based on the masking model and the vector space decomposition ,a new assessment method of image quality is proposed in this paper .T he error image is decomposed to get contrast independent component w hich is compared with the masking threshold ,and the part below the masking threshold is removed .The experimental results show that this method is simple and the image quality is evalua‐ted from two aspects of visual perception and structuralization ,and such evaluation is closer to the subjective feelings of eyes compared with the traditional objective method .
