The comparison of the detection results of subject (3) under gently walking posture. (a) The error produced using the raw data for the 1st time, (b) the error produced using the raw data for the 5th time, (c) the FN produced using the raw data for the 6th time, (d) the error produced using the corrected data for the 1st time, (e) no error using the corrected data using the corrected data for the 5th time, and (f) the error produced using the corrected data for the 6th time.
