OpenBehavior has shared a variety of popular open-source tracking software, and there’s another to add to the list: ToxTrac!
Alvaro Rodriguez and colleagues from Umeå University in Umeå, Sweden, have developed ToxTrac, an open-source Windows program optimized for high-speed tracking of animals. It uses an advanced tracking algorithm that requires no specific knowledge of the geometry of tracked bodies and can therefore be used for a variety of species. ToxTrac can also track multiple bodies in multiple arenas simultaneously, while maintaining individual identification. The software is fast, operating at a rate >25 frames per second, and robust against false positives. ToxTrac generates useful statistics and heat maps in real scale that can be exported in image, text and excel formats to provide useful information about locomotor activity in rodents, insects, fish, etc.
