Identification apparatus and method for identifying properties of an object detected by a video surveillance camera

摘要

The present invention deals with an identification apparatus (100) in a video surveillance system for identifying properties of an object captured in a video sequence by a video surveillance camera. The identification apparatus comprises: an object identification unit (102) for identifying a specific object in a video sequence; a color histogram generator (104) for generating a color histogram in at least two dimensions of a color space based on color and intensity information of the specific object identified in the video sequence, the color and intensity information originating from a plurality of images of the video sequence; and an object properties identificator (106) for identifying properties of the object based on the generated color histogram. The identified properties can then be used in a tracking device (200) of the video surveillance system for tracking an object between different video sequences, which may be captured by two different video surveillance cameras. The present invention also deals with a corresponding method for identifying properties of an object captured in a video sequence and a method for tracking the object in a video surveillance system.
