此处的实现，目标点位将其右下[0,T]范围内的梯度都进行了或操作，即某梯度只向其左上方T大小的范围内进行了扩散，与下文中的T间隔采样暗合，类似于粗略匹配，且针对噪音或微小形变具备较好的鲁棒性，但因此匹配精度上有所欠缺，才有了后续的icp+subpixel finetune。1、linemod论文中，梯度扩散是以当前像素为中心点，从r范围的邻域进行梯度扩散。以上是阅读论文+代码时存在疑惑，记录一下。

转载 Lasso回归算法： 坐标轴下降法与最小角回归法小结
前面的文章对线性回归做了一个小结，文章在这： 线性回归原理小结。里面对线程回归的正则化也做了一个初步的介绍。提到了线程回归的L2正则化-Ridge回归，以及线程回归的L1正则化-Lasso回归。但是对于Lasso回归的解法没有提及，本文是对该文的补充和扩展。以下都用矩阵法表示，如果对于矩阵分析不熟悉，推荐学习张贤达的《矩阵分析与应用》。1. 回顾线性回归 首先我们简要回归下线性回归
