摘要: 为了从眼底图像中获得较多的诊断信息, 有必要对眼底图像进行增强处理. 采用了直方图均衡法对
眼底图像进行增强处理, 并用 MA TLAB 软件进行仿真实验. 通过处理前后图像的对比, 可以看出处理后的眼
底图像的轮廓及细节清晰度明显提高. 说明直方图均衡法对增强眼底图像有较好的效果.

Abstract : In order to obtain more diagnostic information from f undus oculi images , it is necessary to
enhance t he fundus oculi images. The paper adopt s the histogram equalization met hod to enhance the fun
dus image , and does a simulation experiment wit h MA TLAB software. paring t he images before
and after treatment , t he outline and details of t he p rocessed f undus images are imp roved in clarity. It
shows t hat the histogram equalization met hod can enhance fundus oculi images wit h better result s.
