In this paper image content analysis and adaptive background modeling is used to develop a video surveillance system that is suitable for wireless video transmission networks. The proposed system can localize any important information from the video data, i.e. location of a person, and then transmit the important information to the receiver side at the same(More)
In this paper, a new video analysis and background modeling suitable for wireless video surveillance networks is proposed. Using video analysis, the proposed system can detect any location of important information from the video data, e.g., the location of persons, and then the whole video data can be drastically reduced by using background modeling except(More)
