Nearest-Neighbor Clutter Removal for Estimating Features in Spatial Point Processes
利用最近邻去除杂点以估计空间点过程特征
We consider the problem of detecting features in spatial point processes in the presence of substantial clutter. One example is the detection of minefields using reconnaissance aircraft images that identify many objects that are not mines. Our solution uses Kth nearest neighbor distances of points in the process to classify them as clutter or otherwise. The observed Kth nearest neighbor distances are modeled as a mixture distribution, the parameters of which are estimated by…
