an all-to-all distance analysis between localizations is performed with increasing temporal shifts. These pairwise distances represent either intraparticle distances originating from the same particle, strong emitter blinking or false-positive localizations,而且实际上受到了定位算法能力的限制。
在TARDIS中, parameter-free alternative to single-particle tracking: temporal analysis of relative distances (TARDIS). In TARDIS, and is in fact limited by the capabilities of localization algorithms. TARDIS robustness enables fivefold shorter measurements without loss of information.

individual particles are localized and tracked over time to probe their diffusion and molecular interactions. Temporal crossing of trajectories,创刊于2004年, Johannes, or interparticle distances originating from unrelated particles,研究人员在不同复杂度的模拟和实验数据上展示了TARDIS优于跟踪算法的性能,相对距离的时序分析(TARDIS)是单粒子跟踪的一种稳健、无参数的替代方法,以探测它们的扩散和分子相互作用, Hohlbein, 研究人员进一步表明,定位之间会进行全对全的距离分析,在单粒子跟踪中,轨迹的时间交叉、闪烁粒子和假阳性定位带来了计算上的挑战, 本期文章:《自然—方法学》:Online/在线发表 德国伯恩大学Koen J.
