SYSTEM AND METHOD FOR VERY LOW FRAME RATE TELECONFERENCING EMPLOYING IMAGE MORPHING AND CROPPING

A real-time low frame-rate video compression system and method that allows the user to perform face-to-face communication through an extremely low bandwidth network. The system and method employs image cropping and morphing to reduce frame rates. At the encoder side, the system is able to automatically select only a few good faces from the original sequence with high visual quality and compress and transmit them. At the decoder side, the system use image-morphing based rendering method to generate a normal frame-rate video. Experimental results show that the system is superior to more traditional video codecs for low bit-rate face-to-face communication.
