Typically, this is achieved by exploiting the clothing appearance, as classical biometric traits like the face are impractical in real-world video surveillance scenarios. Clothing appearance is represented by means of low-level \\textit{local} and/or \\textit{global} features of the image, usually extracted according to some part-based body model to treat different body parts (e.g. torso and legs) independently.
