Abstract :
In this paper, we present a new blocking scheme for multidimensional transform coding. This scheme generalizes traditional blocking methods. Compared to the conventional rectangular blocking method, the generalized blocking scheme provides us more freedom in choosing block shapes and arrangements, so larger coding gain can be achieved. Examples are presented to illustrate the improvement given by the proposed scheme
