摘　　要：工程施工图像在获取、传输等过程中存在一定程度的噪声干扰。通过对标准中值滤波算法进行分析,得到了一种基于自适应开关中值的图像滤波算法,能够在去除椒盐噪声的同时保持图像细节。该算法用迭代实现了开关中值滤波算法中阈值的自动选取,可有效提高噪声点检测的准确率。通过MATLAB仿真实验,证实了该算法相较于传统滤波算法能够更好地保护图像细节和改进图像清晰度。After obtaining and transmission processing, Engineering image will be always disturbed by a certain degree of noise pollution. Through analysis of standard median filtering algorithm, an adaptive threshold filtering algorithm the is proposed in this paper. This filtering algorithm could automatically chose the threshold for removing mixed noise in digital image. The noise detection veracity is improved obviously. The noise filtering algorithm is tested on the matlab software platform, validate that the algorithm better than the traditional filtering algorithm. It makes the image detail is better pro- tect and the images show more clearly.
