本文设计了一种新的距离度量：边界距离，在此基础上提出了一种二值图像评价的客观方法。该方法首先是得到修改像素点的边界距离对于二值图像的影响因子，然后把该值加入到均方误差法(MSE)中，得到一种改进的基于边界距离的二值图像质量评价，并对其进行规范化。实验结果表明，该方法符合人的视觉感知。

In this paper, we propose a novel distance measure: border distance, and then we propose an objective quality evaluation measure for binary images. Firstly, we get the impact factors of binary images according to the border distance of the modified pixel; then join the impact factors into a mean square error (MSE) and calculate the value BMSE which is based on binary image quality evaluation. Finally, BMSE  is calculated, which is the standardization of BMSE. The experimental results show that the proposed method well matches the subjective apperception of human visual perception.
