本文介绍了两种新的图像增强算法:一种是基于模糊嫡的图像滤波器，另一种是改进的模糊松弛迭代增强算法。前者将图像分为若十窗日，分别计算每个窗日关于不同模糊集的模糊嫡，根据最

小模糊嫡原则，确定该窗日中心灰度的大小，该方法充分利用了图像窗日中像素的区域信息。

-This paper introduces two new image enhancement algorithm: one is based on fuzzy entropy image filters, another improved fuzzy relaxation iterative enhancement algorithms. The former image into the ten windows day, the date of each window on different fuzzy sets fuzzy entropy, were calculated according to the minimum fuzzy entropy principle, determine the size of the window day center gray, full use of the Japan-China pixels of the image window region information.
