Abstract
The dual-tree complex wavelet transform (DT- C WT) is an enhancement of the conventional discrete wavelet transform (DWT) due to a higher degree of shift-invariance and a greater directional selectivity, finding its applications in signal and image processing. This paper presents a quantitative proof of the superiority of the DT- C WT over the DWT in case of modulated wavelets.
