Figure 2From: 2D and 3D analysis of animal locomotion from biplanar X-ray videos using augmented active appearance models Overview of augmented AAMs. Our holistic approach for landmark tracking in X-ray locomotion sequences. The fitting process of standard AAMs is augmented by imposing constraints from methods that only perform well on a subset of landmarks (‘subset AAM’ and ‘local tracking’). Additionally, further knowledge such as anatomical constraints and epipolar priors are included.Back to article page
