Robust single-particle tracking in live-cell time-lapse sequences

Posted on 18/04/2019, in Paper.
  • Overview: This paper proposed a pure CV method to solve the particle tracking in video taking care of splitting and merging events. It is brought up in a biology setting.
  • Two-stage linking: Int the first stage, we constructed track segments by linking the detected particles between consecutive frames; in the second step, we linked the track segments in three ways: End-to-start, end-to-middle, and start- to-middle.
  • LAP: The linking problems from both stages are formulated as LAP (Linear Assignment Problem). In the LAP, we tried to minimize the cost defined by distance and intensity, under the certain constrains that the assignments are mutually exclusive.
