a and c The triple index with thresholds (red and black solid lines) and corresponding upper and lower margins (dashed lines) identified via SVM between normal and abnormal gaits as well as between abnormal and stopping events in two patients respectively. b and d show the time evolution of the triple index with thresholds (red and blue lines) obtained from (a) and (c) for two patients respectively. Blue vertical lines are the transition times in the original data.
