| 摘 要： | 采用直方图均衡和灰度匹配变换的图像增强方法对退化图片细节进行了增强处理，在灰度匹配变换中分别采用单映射（SML）规则和组映射规则（GML），并对它们的特点进行了比较分析．实验结果表明，用SML和GML能更好地增强细节．特别是GML能有效减小其匹配后的直方图与匹配函数之间的误差． |
| 关 键 词： | 退化图片 直方图均衡 单映射 组映射 |

| Abstract: | The enhancement on the detail of degraded picture is obtained by using histogram equalization and gray-level matching transformation,and Single Mapping Law(SML) and Group Mapping Law(GWL) are respectively used in gray-level matching.The characteristics of the methods have been compared.Examples show that it is better to use SML and GML to enhance the detail of the picture,and to reduce the error between matching histogram and matching function,it is better to use GML. |
| Keywords: | degraded picture histogram equalization SML GML |
