Figure 1From: 2D and 3D analysis of animal locomotion from biplanar X-ray videos using augmented active appearance models X-ray acquisition system. Biplanar X-ray acquisition system (I, treadmill; II, lateral X-ray detector; III, dorsoventral X-ray detector) used for locomotion analysis (a). Example data of a quail with typical landmarks (1 to 8, torso; 9 and 16, hip joints; 10, 11, 17, and 18, knee joints; 12, 13, 19, and 20, intertarsal joints; 14, 15, 21, and 22, feet) are shown in (b, c).Back to article page
