Abstract: We propose a novel methodology for person re-identification (Re-ID) based on the biometric description of the upper-torso region of the human body. The proposed methodology leverages soft biometrics via Support Vector Regression (SVR) and Shape Context (SC) features obtained from the upper-torso silhouette of the human body. First, mappings from the upper-torso Shape Context to soft biometrics are learned from virtual avatars rendered by computer graphics engines, to circumvent the need for time consuming manual labelling of human datasets. Second, it is possible to formulate a human query of a given suspect against a gallery of previously stored soft biometrics. At this point, the proposed system is able to provide a ranked list of the persons, based on the description given. Third, an extensive study on the different regression methodologies to achieve the above mentioned mappings is carried out. We also conduct real time Re-ID experiments in an existing Re-ID dataset, and promising results are reported. (More)
