摘　　要：针对雾天红外图像昏暗不清的问题,提出了红外图像增强的均衡化级联GML-规定化处理方法。该方法在对雾天红外图像进行均衡化处理的基础上,采用组映射规则(GML)进行了规定划处理,进而增强了雾天红外图像的清晰程度。仿真结果表明,与采用直方图均衡化或规定化处理相比,提出的直方图均衡化级联GML-规定化处理方法使图像的增强效果更佳。In order to solve the problem of infrared image is dark and nuclear in foggy weather, a novel method that histogram equalization unite with histogram GML-specification is proposed. This method takes histogram equalization in deal with infrared image first, then adopts group mapping law of histogram specification, thus enhancing the clarity of fog infrared images. The experimental results show that which compares with adopts only histogram equalization or histogram specification, and the method of histogram equalization unite with histogram GML-specification is much better in image en- hancement.
