摘要 提出一种新的非线性结构张量计算方法,扩展了基于迹的PDE正则化方法,使其适用于矩阵值数据场;利用该方法平滑结构张量,得到基于迹的非线性结构张量;并给出了新的结构张量在去噪领域的应用.实验结果表明:文中方法具有较好的鲁棒性. A new nonlinear structure tensor calculation method is presented. We extend the trace-based PDE regularization method to matrix-valued data fields. Then, we filter the structure tensor with it and get the trace-based nonlinear structure tensor. This new structure tensor has been successfully applied in noise removal. Experimental results show that our method can produce better results robustly.
