针对光学遥感影像匀光中的马斯克匀光方法的实现需要较大的滤波窗口,易导致匀光的结果对影像中的水体、阴影等存在较大的辐射增强,以及对影像的边缘处理有较大的误差等问题,该文提出改进的马斯克匀光方法:首先生成背景影像;然后对输入影像与获得的背景影像复合进行锐化增强;最后对锐化增强的结果进行拉伸处理。试验结果表明,该方法可以在滤波器窗口为3或5的情况下在对影像匀光的同时实现锐化增强。
For the realization of the optical remote sensing image uniform Musk uniform light method requires a large filtering window, easily lead to the result of uniform light on the image of water, shadow and so there is a greater radiation enhancement, and the edge of the image processing Large error and so on. In this paper, an improved method of Musk-Dichroic is proposed. First, the background image is generated. Then, the input image and the obtained background image are sharpened. Finally, the result of the sharpening enhancement is stretched. Experimental results show that this method can achieve sharp sharpening while the image is uniform with 3 or 5 filter windows.
