Observing the dynamics of living cells and subcellular components is crucial for understanding fundamental biological processes. Time-lapse microscopy at the cellular and molecular level is a valuable tool for this purpose, but extracting quantitative information from these experiments can be challenging. In this talk, I will present our advances in data-driven methods for object tracking and analysis, including machine learning algorithms that offer remarkable improvements over classical methods. Specifically, I will discuss the results of an objective assessment of the performance of these methods for trajectory analysis and their follow-up applications. Furthermore, I will introduce novel strategies that we are currently developing to move beyond the tracking-by-detection paradigm. Through these methods, we hope to uncover new insights into the interactions between cellular components and their role in signaling and function regulation.
