眼底图像是细节较多的复杂图像，Ｐａｌ等人提出的模糊增强算法对增强这类图像有着较好的效果。但这种算法存在着处理速度较慢和容易损失信息的缺陷。针对这一情况，本文提出了一种改进后的模糊增强算法。实验证明，改进后的模糊增强算法对眼底图像的增强有着更好的效果。
The fundus image is a complicated image with more details. The fuzzy enhancement algorithm proposed by Pal et al. Has a good effect on enhancing such images. However, this algorithm has the disadvantage of slow processing and easy loss of information. In response to this situation, this paper presents an improved fuzzy enhancement algorithm. Experiments show that the improved fuzzy enhancement algorithm has a better effect on the fundus image enhancement.
