From: A novel method for robust markerless tracking of rodent paws in 3D
A video (MP4 82.3 MB) of tracked paws for 100 consecutive frames which compare the results between MT and our proposed method (OPM). The filled and unfilled circles show the tracked paws using the cameras located on the same side of paws and the remapped of paws locations to the other side cameras relative to the paw side, respectively. The unfilled circles show the concept of transferring 2D coordinates to 3D and remapping the 3D coordinates to 2D images (in this figure to other cameras while it can come back to the same cameras and finding the 3D reconstruction error). The red, blue, green, black, cyan, yellow, magenta, and white show the tracked coordinates of paws for front right by MT, hind right by MT, front left by MT, hind left by MT, front right by OPM, hind right by OPM, front left by OPM, and hind left by OPM
