Abstract

Using one filter over another can greatly affect the performance of a wavelet system without changing other vital factors. In this paper, various wavelet filter sets will be evaluated and their performance will be judged based on a set of criteria, namely energy compaction and filter tap-size, given that the former provides a tighter performance constraint and the latter directly correlates with execution time. Since, a universal filter tuned for every single application does not yet exist, the proposed evaluation can help in providing a guideline to where certain filter sets should, or should not, be used in order to best exploit them in a given application.
