| 摘 要： | 针对声呐图像噪声污染严重的问题,在基于形态小波的声呐图像去噪方法中引入了谱聚类算法以实现低信噪比下图像的去噪.给出基于形态中点小波的声呐图像去嗓法,在此基础上引入谱聚类的概念,针对谱聚类能快速实现数据分类的特点,对形态中点小波分解后的高频小波系数进行分类,使得包含噪声与细节信号部分的小波系数得以分离.对分离后的两类小波...

| Abstract: | Aiming at the serious noise pollution problems in sonar image,spectral clustering algorithm is introduced into denoising method based on morphological wavelet in order to realize image denoising with low SNR.Sonar image denoising method based on morphological midpoint wavelet is given.The concept of spectral clustering is introduced and used for the classification of high-frequency wavelet coefficients after morphological midpoint wavelet decomposition because of its fast data classification features.The wa... |
