摘要:
A cascadable camera tampering detection transceiver module has a processing unit and a storing unit, an information controlling module and an analyzing module. The storing unit stores a transceiving module. The detection module analyzes input video, detects camera tampering events, synthesizes the input video with the image of camera tampering result, and outputs the synthesized video. When the input video is an output from the detection module, the detection module separates the camera tampering result from the input video, and the result can be used to simplify or enhance the subsequent video analysis. Performing the existing analysis repeatedly may be avoided, and the user may re-define the detection conditions in this manner. When the camera tampering result is transmitted in the video channel, the detection module transmits the camera tampering result, and hence the detection module may be used in combination with surveillance devices having image output or input interfaces.

摘要:
A moving object detection method and a moving object detection apparatus based on a compressed domain are disclosed. In the method, compressed video data and pixel video data are received. Moving object information in the first compressed video data is detected and integrated into the pixel video data. The pixel video data containing the moving object information is output.
