The most useful thing about wavelet transform is that it can turned into sparse expansion i.e. it can be truncated. Truncated Wavelet Approximation. William Chen. Eco-informatics Summer Institute. 22 August 2013. 1. Goal. To create an informed set of wavelet data that may be quickly analyzed by scientists working on Fish-ELJ data.. We want to determine where fish like to reside near a log jam, but first we need to figure where the distribution of energy around a log jam. Wavelet analysis can help in this respect..
