Automatic hoof-on and -off detection in horses using hoof-mounted inertial measurement unit sensors

M. Tijssen , E. Hernlund, M. Rhodin, S. Bosch, J. P. Voskamp, M. Nielen, F. M. Serra Braganςa, June 3, 2020, PLOS ONE, https://doi.org/10.1371/journal.pone.0233266    For gait classification, hoof-on and hoof-off events are fundamental locomotion characteristics of interest. These events can be measured with inertial measurement units (IMUs) which measure the acceleration and angular velocity in three directions. The aim of this
