Human Skeleton Model Based Dynamic Features for Walking Speed Invariant Gait Recognition
Figure 5
Example of extracted features: image shows extracted mass, thigh1, and knee1 signals (in columns) of several gait cycles for three subjects (rows (a), (b), and (c)) denoted by s# 1, s# 2 and s# 3. Blue lines indicate signals, red-thick lines indicate signals mean, and red-dashed lines indicate intraclass variance. Row (d) shows mean and variance (interclass) of all the signals for all subjects (s# all).
