Abstract :
In this paper, we present a very efficient shape-adaptive coding method which is a hybrid between the standard SA-DCT and the padding technique we proposed in our early work [1999]. This hybrid has led to a significantly lower computation burden while the coding performance is improved. This conclusion is proved by thorough complexity analysis and extensive simulation. This method also has the shape preserving property and exhibits asymmetric complexities between the encoder and the decoder
