A novel data structure is proposed for magnitude-ordering 3-D wavelet transform coefficients. This data structure consists of temporal 1-D orientation trees followed by spatial 2-D orientation trees. Based on this data structure, a coding algorithm is developed for the embedded coding of 3-D wavelet transform coefficients. Experiment results confirm that the proposed coding algorithm outperforms a conventional algorithm that uses asymmetric 3-D orientation trees. [ABSTRACT FROM AUTHOR]
