An effective padding scheme, called the smart padding (SmartPad), has been developed recently for the DCT coding of arbitrarily-shaped image/video objects ; whereas its superior performance over the NWEG-4's LPE padding has been confirmed solidly. In the present paper, we propose to extend the use of SmartPad to all INTER frames (of arbitrary shapes), i.e., to use SmartPad to replace the zero padding scheme (as recommended in MPEG-4). Our simulation results show that a very substantial performance gain (3-7 dB) has been achieved, as compared to the M-PEG-4's LPE/zero padding scheme.
