In this paper, we derive the rate distortion lower bounds of spatially scalable video coding techniques. The methods we evaluate are subband and pyramid motion compensation where temporal redundancies in the same spatial layer as well as interlayer spatial redundancies are exploited in the enhancement layer encoding. The rate distortion bounds are derived from rate distortion theory for stationary...
In this paper, we derive the rate distortion performance lower bound of the subband motion compensation technique which exploits both the inter-layer spatial and intra-layer temporal redundancies for video spatial scalability. The lower bound is derived by rate distortion theory for stationary Gaussian signals where mean square error (MSE) is used as the distortion criteria. Assuming that the base...
