The study of animal behavior by analyzing recordings can be very labor-intensive if done by hand. To solve this problem, many  automated image tracking applications were developed. All of them are either too complex to use or too specialised  to be a solution  fitting various tracking problems. To overcome these issues, an open source tracking framework called "BioTracker" was designed. It aims to cover many tracking scenarios by giving the possibility of creating your own tracker, while still providing high usability. The goal of this thesis is to improve the user experience of the BioTracker by implementing a generic visualization of tracking data and by adding new features to an optimized user interface.
