Although the discrete wavelet transform (DWT) is a powerful tool for signal and image processing, it has three serious disadvantages: shift sensitivity, poor directionality, and lack of phase information. To overcome these disadvantages, we introduce

Summary Seismic attribute analysis has gone through a major revolution due to the introduction of three-dimensional seismic imagery. Features of special interest are the local geometry of the seismic signal and its frequency content. We have develope

Complex wavelet transforms offer the opportunity to perform directional and coherent processing based on the local magnitude and phase of signals and images. Although denoising, segmentation, and image enhancement are significantly improved using com
