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。
工程施工圖像在穫取、傳輸等過程中存在一定程度的譟聲榦擾。通過對標準中值濾波算法進行分析，得到瞭一種基于自適應開關中值的圖像濾波算法，能夠在去除椒鹽譟聲的同時保持圖像細節。該算法用迭代實現瞭開關中值濾波算法中閾值的自動選取，可有效提高譟聲點檢測的準確率。通過MATLAB倣真實驗，證實瞭該算法相較于傳統濾波算法能夠更好地保護圖像細節和改進圖像清晰度。
