However, it is possible that the octave analysis is not necessarily the most suitable to match the analysis signal. In this study, in order to construct the most suitable basis to match the analysis signal, a novel variable-filter band discrete wavelet transform (VFB-DWT) is proposed. It is achieved by using variable-band filters instead of conventional decomposition and reconstruction sequences, which are designed in consideration of the real signal characteristics. Additionally, it is proven that perfect reconstruction of the analysis signal by VFB-DWT is guaranteed using the perfect shift invariant theorem that underlies the theory of the PTI-CDWT having base DWT. <\/jats:p>","DOI":"10.1142\/s0219691314600066","type":"journal-article","created":{"date-parts":[[2014,2,7]],"date-time":"2014-02-07T11:39:21Z","timestamp":1391773161000},"page":"1460006","source":"Crossref","is-referenced-by-count":0,"title":["A novel variable filter band discrete wavelet transform: Theory and principle"],"prefix":"10.1142","volume":"12","author":[{"given":"Zhong","family":"Zhang","sequence":"first","affiliation":[{"name":"Department of Mechanical Engineering, Toyohashi University of Technology, 1-1, Hibarigaoka, Tenpaku, Toyohashi 441-8580, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiroshi","family":"Toda","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Toyohashi University of Technology, 1-1, Hibarigaoka, Tenpaku, Toyohashi 441-8580, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takashi","family":"Imamura","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Toyohashi University of Technology, 1-1, Hibarigaoka, Tenpaku, Toyohashi 441-8580, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tetsuo","family":"Miyake","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Toyohashi University of Technology, 1-1, Hibarigaoka, Tenpaku, Toyohashi 441-8580, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2014,8,13]]},"reference":[{"volume-title":"An Introduction to Wavelets","year":"1992","author":"Chui C.
