Description: 许多特征跟踪算法已被提出
为运动分割,但由此而轨迹
不一定是正确的。在本文中,
我们提出一种技术用于去除野值的基础上
在对知识,正确的轨迹约束的
在他们的网域的子空间的。我们第一次
合适的子空间的轨迹鲁检测
然后用RANSAC移除那些大型
后遗症。使用真实的视频序列,我们证明了
我们的方法是有效的,即使多个对象
移动在场景里。我们也证实分离
我们确实是提高精度的方法。
-Many feature tracking algorithms have been proposed
for motion segmentation, but the resulting trajectories
are not necessarily correct. In this paper,
we propose a technique for removing outliers based
on the knowledge that correct trajectories are constrained
to be in a subspace of their domain. We first
fit the subspace to the detected trajectories robustly
using RANSAC and then remove those that have large
residuals. Using real video sequences, we demonstrate
that our method is effective even if multiple objects are
moving in the scene. We also confirm that the separation
accuracy is indeed improved by our method.

Description: 八叉树k邻域搜索思路和数据精简,点云数据P的K近邻指的是在物体空间内，点云数据内与P相邻的K个最近相邻点。这里采用八叉树分割法来搜索点P的K近邻。具体步骤是：先设定一个距离阈值，根据已知的P点坐标，可以求得相应的子立方体结点编号以及相邻的26个子立方体编号，每个子立方体记录下编号后，先在该子立方体内部搜索距离阈值范围内的K个近邻点，如果点数不够，则在其相邻的26个子立方体里面搜索，直到满足要求结束。
