Shearlet Transform 剪切波变换
Non-Subsampled Shearlet Transform 非下采样剪切波变换
Two shearlet-based denoising methods using trivariate prior model are proposed for image denoising. The dependency among shearlet coefficients is analyzed via mutual information.
针对图像去噪问题, 提出了两种基于三变量模型的剪切波去噪方法。 首先利用互信息对剪切波系数间的依赖关系进行量化分析;
