一种改进的EMD图像信号去噪算法
An improved signal denoising algorithm of EMD image
摘要
Abstract
Since the current threshold algorithm may filter the useful components of the original image and destroy the image integrity while denosing the image,and the processed image is fuzzy,an EMD⁃SG algorithm is proposed to denoise the image. According to the EMD algorithm,the image is split,and the SG filter is used to filter the neighborhood of each collection point. The least square method is used to fit the best value inside the neighborhood of the acquisition points,and the image is recon⁃structed with IMF. This algorithm takes the image signal integrity and image denoising effect into account well in the image pro⁃cessing procedure. The experimental results show that,in comparison with other algorithms,this algorithm has excellent denois⁃ing ability.关键词
