Abstract:

This paper examines the properties of a recently introduced 3-D dual-tree discrete wavelet transform (DDWT) for video coding. The 3-D DDWT is an attractive video representation because it isolates motion along different directions in separate sub bands. However, it is an over complete transform with 8:1 redundancy. We examine the effectiveness of the iterative projective-based noise-shaping scheme proposed by Kingsbury [3] on reducing the number of coefficients. We also investigate the correlation between sub bands at the same spatial/temporal location, both in the significance map and in actual coefficient value.
