摘　　要：为了消除或衰减扫描图像的噪声 ,同时尽可能保留图像细节 ,提出了一种数学形态学金字塔扫描图像降噪方法。使用形态金字塔算法将扫描图像逐级分解 ,在不同分辨率空间中对细节信息集进行滤波处理 ,用处理后的细节信息重图像。仿真结果表明该算法是有效的 ,同传统的中值滤波相比 ,能够更好地消除扫描噪声、保留边缘。In order to eliminate the noise and preserve the fine structure features of the scanned image, a method of scanned image denoising based on mathematical morphological pyramid is proposed, which is used to decompose an image level-wise and the detail information is filtered in different resolution spaces, finally restructure a cleaned image with the detail information processed. Experiment results demonstrates that the efficient of the proposal method, and the method, Compared with conventional median filter, the method is of the advantages for eliminating scanned noise, fine edges preserving.
