Panoramic Image Generation based on FFT Technique and its Hardware Realization

In most of the current teleconferencing systems, a full view image of a conference room and voice of speakers are bidirectionally exchanged between distant places. However, in teleconferencing situations, face images of speakers are also requested to perceive facial expression. To take both full view images of a conference room and face images of speakers, it is required to develop a multi camera system with human operations. In this paper, we develop a new video camera for teleconferencing without human operations in above mentioned situations. The proposed video camera outputs the images which composed with panoramic images generated with images from three NTSC video cameras and the facial images of speakers. In this paper, hardware realization of the fast robust correlation technique proposed by Fitch et al. is described
