However, there seems to be a lack of understanding within the geophysicalcommunity regarding why total variation regularization allows dipping structuresto be recovered, whereas _1 norm regularization does not. In this paper, we comparethese two regularization strategies from an optimizati...
2) regularization variation 正则化变分 1. Based on the idea of SAR image processing and the prior knowledge of SAR image,we presented an adaptive regularization variation method by constructing diffusion coefficient and regularization parameter. 传统的SAR图像相干斑抑制方法通常会导致边缘和目标的模糊,...

To further improve the accuracy of hyperspectral unmixing, we propose a novel linear hyperspectral unmixing method based on l(1)-l(2) sparsity and total variation (TV) regularization. First, the enhanced sparsity based on the l(1)-l(2) norm is explored to depict the intrinsic sparse ...
