Surveillance system

摘要

A surveillance system includes an input unit to receive a plurality of video frames that are acquired through the use of a first camera, a video processing unit to perform prediction and encoding processes on the plurality of video frames, a moving-object tracking unit to track a moving object between the video frames based on at least part of the results from the prediction and encoding processes to generate location information of the moving object being tracked, and a control unit to generate a control signal based on the location information and to transmit the control signal to a second camera to control the movement of the second camera.

1. A surveillance system comprising:
an input unit configured to receive a plurality of video frames that are acquired through a first camera; a video processor configured to generate prediction information and encoding information on the plurality of video frames that have been encoded; a moving-object tracking processor configured to:
track a moving object in the plurality of video frames based on at least part of the prediction information and the encoding information;perform a first motion classification to identify a list of candidate image areas in the plurality of video frames for the moving object based on the prediction information and the encoding information;weight each candidate image area identified in the list of candidate image areas, wherein a greater weight is given to candidate image areas determined from the prediction information and a lesser weight is given to candidate image areas determined from the encoding information;perform a second motion classification on each of the candidate image areas in the list of candidate image areas based on the weights of the candidate image areas and on additional prediction information or additional encoding information to eliminate some of the candidate image areas in order to identify final image areas from the list of candidate image areas; andgenerate location information of the moving object based on the final image areas; and a camera control processor configured to generate a control signal based on the location information and to transmit the control signal to a second camera to control movement of the second camera effective to capture a feature part of the moving object.
