| 摘 要： | 图像增像是图像处理的一个重要步骤之一,而直方图均衡化是经典图像信息增强算法之一,但它并不是对于所有图像均适用.本文提出了一种暗背景图像自适应增强的算法,根据直方图对图像进行分类,对属于暗背景的图像采用S形非线性函数进行增强.

| Abstract: | Image enhancement is one of the important methods of image processing.The histogram-equalization,a traditional enhancement algorithm,has several drawbacks to process some images.In this paper,a new method of adaptive enhancement of image with dark-ground has been proposed based on the classification of the image's histogram.Different images should be treated with different methods of enhancement;for an image with a large area of dark background,using the nonlinear S function would be a good choice. |
