| 摘 要： | 为了提高夜间图像的清晰度，文中提出了一种适用于此类图像增强的新算法，其特点为： １） 将对比度增强算法与直方图均衡算法级联，使得图中的局部信息与全局信息在增强时都能被利用； ２） 经对各种函数的实际处理效果进行比较，提出了一个适合夜间图像增强的对比度变换函数。实践证明新方法在处理夜间图像时能得到比较理想的结果

| Abstract: | In order to improve the clearness of images captured at night, a new enhancement algorithm was proposed in this paper. Its characters are: 1) enhancing the dark image with contrast enhancement and histogram equalization in series. Both the local and global information can be used; 2) after comparing the results of different functions, a contrast transforming function which is suited to deal with dark image is proposed. The new method shows good performance in dealing with night vision images. |
