The criterion to evaluate the algorithms will be the sum of the exponential of the time differences between to the computed gait events and the gold-standard values of the gait events. The code that computes the score is availble with the data. The gait event detection algorithm with the lowest score will win the challenge. The time for calculating the detection will also be taken into account.For each event with a detection time above 0.5s a penalty of 10 frames will be added before applying the exponential.
All algorithms will be evaluated on a second database of patients with similar impairements.
