Automatic methods of hoof-on and -off detection in horses using wearable inertial sensors during walk and trot on asphalt, sand and grass
Fig 3
Illustration of the novel methods.
Novel methods M1 (A and D) and M2 (B and E), and reference method Mref (C and F) are illustrated; blue windows are examples of the frames in which relevant peaks were sought; down triangles (A-C) indicate hoof-on and up triangles (D-F) hoof-off; the sensor locations (hooves, pasterns and/or cannons) for which each method is applicable are shown in illustrations on the right.
