| 摘 要： | 针对均值滤波和中值滤波的不足，提出一种改进的基于双阈值滤波算法。该算法通过两个阈值和均值的关系来判断当前点应取的值。和传统的滤波算法相比．该算法在滤出噪声的同时，能最大限度保留原始图像信息，滤波效果较好。

| Abstract: | According to the defects of mean filter and mid-value fiher, proposes an improved threshold filtering algorithm based on double. This algorithm uses the relationship between two thresholds and means to determine the current point the value should be. Comparing with traditional fil- tering methods, this algorithm can remove noises better, and at the same time, it can retain the original image information. |
