图像质量评价的研究已成为图像信息工程的基础技术之一。由于图像的最终接受者是人，所以评价图像质量应反映出人类的主观视觉感知。为构造一种符合人眼视觉特性的图像质量评价方法，利用点扩散函数针对人眼建立了含有波前像差信息的图像视觉评价模型，并用此模型分别对添加不同噪声的图像进行图像质量评价。实验结果表明，该方法是可行的、有效的，不同的人眼对同一幅图像的评价存在有差异，人眼波前像差越小观察到的图像越清晰。该方法不仅能够在评价图像质量时准确反映人眼的主观感知，而且能够直观地呈现不同人眼实际看到的图像。

Research on image quality assessment is meaningful for image processing projects. Since human being is images’ final receiver, image assessment should reflect human's subjective visual perception. In order to establish a new image quality assessment method which conforms to the human eye visual features, The image visual evaluation models which has the human eyes’ aberration information was constructed by using point spread function. With these models we evaluated images which were added noise. Result shows that this method is feasible and effective. Evaluations of different eyes on one image are different, and the smaller the human eye aberration is the clearer the image we observe. This method not only can reflect the subjective perception of the human eye, but also to present the actual images in different eyes intuitively.
