THE CONTINUOUS WAVELET TRANSFORM: MOVING BEYOND UNI‐ AND BIVARIATE ANALYSIS

Journal of Economic Surveys, 2014
A body of work using the continuous wavelet transform has been growing. We provide a self-contained summary on its most relevant theoretical results, describe how such transforms can be implemented in practice, and generalize the concept of simple ...

The wavelet transform, time-frequency localization and signal analysis

IEEE Transactions on Information Theory, 1990
Two different procedures for effecting a frequency analysis of a time-dependent signal locally in time are studied. The first procedure is the short-time or windowed Fourier transform; the second is the wavelet transform, in which high-frequency ...

Image coding using wavelet transform

IEEE Transactions on Image Processing, 1992
A scheme for image compression that takes into account psychovisual features both in the space and frequency domains is proposed. This method involves two steps.

Wavelet transform for Fresnel-transformed mother wavelets

Chinese Physics B, 2011
In this paper, we propose the so-called continuous Fresnel-wavelet combinatorial transform which means that the mother wavelet undergoes the Fresnel transformation. This motivation can let the mother-wavelet-state itself vary from |〉 to F†r,s|〉, except for variation within the family of dilations and translations. The Parseval's equality, admissibility
