Recording the Region of Interest from FlyCam Panoramic Video


A novel method for region of interest tracking and recording
video is presented. The proposed method is based on the FlyCam system, which produces high resolution and wide-angle
video sequences by stitching the video frames from multiple
stationary cameras. The method integrates tracking and
recording processes, and targets applications such as classroom lectures and video conferencing. First, the region of interest (which typically covers the speaker) is tracked using a Kalman filter. Then, the Kalman filter estimation results are used for virtual camera control and to record the video. The system has no physical camera motion and the virtual camera parameters are readily available for video indexing. The proposed system has been implemented for real time recording of lectures and presentations.
