Fig. 3: 3D position trajectory of a marmoset over a period of 5 min.
From: Development of a 3D tracking system for multiple marmosets under free-moving conditions

a Marmoset trajectories analyzed by Lidar. White points indicate centroid of marmosets. b Lidar and video tracking. Different colors were assigned to each tracking serial number that numbered the background. c Lidar and video trajectory tracking combined with face recognition. Green: marmoset A; red: marmoset B; yellow: marmoset C.
