提出了一种基于上下边界估计的快速图像增强方法。该方法使用上边界提升图像的细节信息，使用下边界消除图像的雾霾成分，调整上下边界的距离可灵活控制图像增强的程度，在上下边界计算过程中采用了加权中值滤波，能够在有效去噪的同时保持图像边界清晰。实验结果表明，该算法能有效改善图像质量，保持图像细节信息，压缩图像动态范围，色彩逼近于真实环境，且避免了光晕的产生。

A novel image enhancement algorithm based on estimating the upper and lower boundary is presented.The method employs the upper and lower boundary to adj ust the image details adaptively and dehaze the image,respectively and control the extent of image enhancement flexibly by adjusting the distance between the upper and lower boundary.The weighted median filter is adopted to calculate the upper and lower boundary for preserving image edges.Simulation results show that the proposed algorithm can improve the visual quality of the image efficiently,preserve the details,compress the high dynamic range,reduce halo artifacts and make the image more realistic and natural.
