New Developments of Wavelets in Flow Visualization
Hui Li · Journal of the Visualization Society of Japan · 2002
The application of the wavelet transform in the field of fluid mechanics started from 1988. In the past decade, there has been a great progress for studying turbulence in the use of wavelet transform. In this article the generally properties of the wavelet transform are first reviewed from the view of fluid mechanics applications. Then an overview of some applications on flow visualization, such as turbulent image analysis, PIV vector multi-resolution analysis, PIV image compression, and PIV results compression, are described.
