基于小波线性最小均方误差的红外图像去噪

摘要

根据小波多尺度线性最小均方误差估计方案的小波基选择标准来确定最佳小波基.在此基础上,对红外图像中的散斑噪声运用取对数方案,并进行硬阈值处理,从而达到去噪目的.%Based on the wavelet multi-scale linear minimum mean square error estimation scheme in the wavelet base selection criteria, this paper determined the optimum wavelet base. On this basis,used logarithmic scheme to the IR image speckle noise mage, and dealt with hard threshold denoising processing, so as to achieve the purpose of denoising.
