Gait recognition to be the recognition of some salient property, e.g., identity, style of walk, or pathology, based on the coordinated, cyclic motions that result in human locomotion. In the case of biometric gait recognition, the salient property is identity. We make the distinction between gait recognition and what we call quasi gait recognition in which a salient property is recognized based on features acquired while a subject is walking, but the features are not inherently part of the gait. For example, skeletal dimensions may be measured during gait and used to recognize an individual.
