3Security Sphere: Digital Image Processing by

This thesis presents an intelligent motion detection algorithm and a real-time video compression scheme for use in a proposed wireless, panoramic surveillance device named the Security Sphere. The motion detection algorithm recognizes repetitive motion and ignores the motion of small or narrow objects in an attempt to trigger only upon human motion. A wireless surveillance device equipped with this motion detection feature could save power, issue alerts, or eliminate the need for a human monitor of the video output. The algorithm is implemented on a TMS320C6211 digital signal processor. The video compression reduces the video data rate for transmission of the data over a 2.5-Mb/s wireless channel. The video compression scheme performs wavelet-transform based intraframe compression independently on each frame of video. The compression is implemented through the use of the ADV601 wavelet compression chip. A demonstration platform was developed that tests the motion detection and compression features using the output from a 60-frame-per-second digital video camera. The compressed and subsequentl
