摘要

本文提出了一种测量JPEG-2000编码图像感知图像质量的方法。图像质量的特征是图像中的平均边缘扩展，或者更具体地说，是相反梯度方向上边缘的斜率扩展的平均程度。所提出的方法实际上是一种测量图像模糊程度的方法。通过主观测试验证了该方法的有效性，实验结果表明，该方法可以提供与人类主观评分相对相关的结果。

No-reference JPEG-2000 image quality metric

In this paper, a method for measuring the perceptual image quality of JPEG-2000 coded images has been proposed. The image quality is characterized by the average edge-spread in the image, or more specifically the average extent of the slope's spread of an edge in the opposing gradients' directions. The proposed method is, in effect, a way of measuring the amount of blurring in the image. The effectiveness of such method is validated using subjective tests and the experimental results show that the proposed method can provide results that correlate relatively well with human subjective ratings.
