The gestures are represented by spatio-temporal templates. This template collapses spatial and temporal components of motion into a static gray scale image such that no explicit sequence matching or temporal analysis is required, and it reduces the dimensionality to represent motion. These templates are modified to be invariant to translation and scale. Two-dimensional, 3-level dyadic wavelet transforms have been applied on the template resulting in one lowpass sub-image and nine highpass directional sub-images. Histograms of wavelet coefficients at different scales are used for classification purposes. The experiments demonstrate that while the statistical properties of the template provide high level of classification accuracy, the global detail activity available in highpass decompositions significantly improve the classification accuracy. <\/jats:p>","DOI":"10.1142\/s0219691304000512","type":"journal-article","created":{"date-parts":[[2004,8,30]],"date-time":"2004-08-30T11:36:17Z","timestamp":1093865777000},"page":"283-298","source":"Crossref","is-referenced-by-count":2,"title":["WAVELET DIRECTIONAL HISTOGRAMS OF THE SPATIO-TEMPORAL TEMPLATES OF HUMAN GESTURES"],"prefix":"10.1142","volume":"02","author":[{"given":"ARUN","family":"SHARMA","sequence":"first","affiliation":[{"name":"School of ECE, RMIT University, GPO Box 2476V Melbourne, Victoria, Australia 3001, Australia"}]},{"given":"DINESH K.","family":"KUMAR","sequence":"additional","affiliation":[{"name":"School of ECE, RMIT University, GPO Box 2476V Melbourne, Victoria, Australia 3001, Australia"}]},{"given":"SANJAY","family":"KUMAR","sequence":"additional","affiliation":[{"name":"School of ECE, RMIT University, GPO Box 2476V Melbourne, Victoria, Australia 3001, Australia"}]},{"given":"NEIL","family":"McLACHLAN","sequence":"additional","affiliation":[{"name":"School of Aerospace Engineering, RMIT University, GPO Box 2476V Melbourne, Victoria, Australia 3001, Australia"}]}],"member":"219","published-online":{"date-parts":[[2011,11,21]]},"reference":[{"key":"rf1","doi-asserted-by":"publisher","DOI":"10.1006\/cviu.1998.0744"},{"key":"rf2","doi-asserted-by":"publisher","DOI":"10.1016\/0262-8856(95)93154-K"},{"key":"rf3","doi-asserted-by":"publisher","DOI":"10.1006\/cviu.2000.0897"},{"key":"rf4","doi-asserted-by":"publisher","DOI":"10.1109\/72.182690"},{"key":"rf6","doi-asserted-by":"publisher","DOI":"10.1109\/38.250916"},{"key":"rf7","volume":"36","author":"Wang L.","journal-title":"Pattern Recog."},{"key":"rf9","first-page":"28","author":"Baudel T.","journal-title":"CACM"},{"key":"rf10","doi-asserted-by":"publisher","DOI":"10.3758\/BF03212378"},{"key":"rf11","first-page":"76","author":"Johnsson G.","journal-title":"Scient.
