A method for monitoring a person of interest in video that may be generated by multiple cameras in different locations. A sequence of images along with data such as time and location, called a tracklet, may be generated for the person of interest. This reference tracklet may then be compared to other tracklets received at later times to determine if the person of interest appears in these other tracklets. Analyses may include locating persons in the video images, calculating person signatures, and comparing signatures to signatures of the person of interest. Analyses may also include filters for possible locations of the person of interest based on how quickly this person could move from one location to another, and filters based on color of the person of interest's clothing. Possible matches may be confirmed by an operator, while matches with high confidence may be automatically identified as the person of interest.

Method for assisting real-time monitoring of at least one person on sequences of images

An electronic device for identifying and tracking at least one target, including: a receiver module configured to receive images from a network of image sensors; a determination module configured to determine visual signatures of a respective target from the received images, each visual signature being determined from a respective image including a representation of the target, each visual signature being in the form of a vector in multi-dimensional space; a first filtering module configured to filter the visual signatures; a computation module configured to compute a reference visual signature, in multi-dimensional space; a detection module configured to detect an appearance of the target, and a second filtering module.
