基于自适应鲁棒估计器的TPC跟踪算法
Tracking Algorithms for TPCs using Consensus-Based Robust Estimators
摘要：
针对时间投影室的实验分析，提出了一种基于一致性鲁棒估计的跟踪算法。在这项工作中，RANSAC以外的一些算法成功地测试了使用AT-TPC，ACTAR和TexAT检测器的实验数据。本跟踪算法比简单的顺序RANSAC例程具有更好的内野检测。在随机抽样和聚类的修改，包括提高跟踪效率。在所有测试情况下都获得了非常好的结果，特别是在检测限中拟合短轨迹。
英文摘要：
A tracking algorithm based on consensus-robust estimators was implemented for the analysis of experiments with time-projection chambers. In this work, few algorithms beyond RANSAC were successfully tested using experimental data taken with the AT-TPC, ACTAR and TexAT detectors. The present tracking algorithm has a better inlier-outlier detection than the simple sequential RANSAC routine. Modifications in the random sampling and clustering were included to improve the tracking efficiency. Very good results were obtained in all the test cases, in particular for fitting short tracks in the detection limit.
