Separation of Dynamic and Static Images by Modal-Wavelets

Abstract

Animation is divided into static and dynamic images by the modal-wavelets. The modal-wavelet transform is proposed as one of the discrete wavelets derived from a modal analysis to a potential field. One of the distinguished features is that the modal-wavelet transform is free from the number of the elements composing target data. It is useful to handle animation data having high resolution as well as large number of frames. This new method is applied to visualized eddy flow animation in order to divide it into the static and dynamic images. As a result of the modal-wavelet analysis, the core of eddy flow can be extracted in the separated static image.
