中文摘要：

针对东巴经典古籍数字化过程中存在噪声干扰的问题,采用中值滤波的方式进行图像去噪,虽然中值滤波有较好的去除噪声能力,但对图像的细节信息有一定的损坏。进一步引入自适应算法,对其进行优化。经过实验验证,自适应中值滤波算法可以根据设定条件,通过检测噪声点来改变滤波窗口的大小,在保护图像质量的同时抑制噪声信号,具有良好的滤波特性。

英文摘要：

Aiming at the noise problem in Dongba Manuscripts digitization,the way of median filtering is adopted for image denoising of Dongba Manuscripts. Although median filter has good ability to remove the noise but causes certain damage to the detailed image information. Therefore,the adaptive median filtering is introduced. Test shows that the adaptive median filtering can not only protect the characteristics of the image but also restrain noise signal at the same time.
