Overview of the CatWalkXT® automated gait analysis system.
The hood is elevated to obtain a better overall impression of the walkway. For gait analysis, the hood is closed creating a tunnel guiding the animals direction of movement (A, image provided Noldus Information Technology, Wageningen, The Netherlands). Fruthermore, an example of automated CatWalkXT® footprint recognition is provided (B).
