Method and apparatus for selecting the optimal video frame to be transmitted to remote stations for residential security monitoring of CCTV-based

摘要

Security monitaringushisutemu, in the detector and the structure which inspect the warning which is in the structure and/or has with the modem which transmits subset of the processor and the graphics data which at least select the subset of the picture the time of one which captures the graphics data outside camera and warning on the basis of specified standard to remote position. At least, one camera is the video camera, the graphics data is the video graphics data, it is desirable for subset of the graphics data to be at least one video frame of the video graphics data. As for the processor, each video frame satisfies some specified standard well following, ranking it does to attach each video frame from the graphics data, modem transmits video frames of a specified quantity which possesses the highest ranking attaching to remote position. Whether or not as for specified standard, the finite difference territory is on some center in the video frame, the finite difference territory which is large, whether the finite difference territory where the finite difference territory is large is included whether the group of the small finite difference territory is included, whether the face was detected contrast of the finite difference territory, in illumination state, and the finite difference territory for the finite difference territory, the video frame has been off-center, skin color which is included in the video frame, the person is recognized in the video frame whether, and, it is desirable to be selected from the group which consists of an illumination state for the moving territory of the video frame.
