The hand object is detected with a double-active contour-based method. A tracking of the hand pose in a short sequence allows detecting \"modified poses\", like diacritic letters in national alphabets. The static hand pose set corresponds to hand signs of a thumb alphabet. Finally, by tracking hand poses in a longer image sequence, the pose sequence is interpreted in terms of gestures. Dynamic Bayesian models and their inference methods (particle filter and Viterbi search) are applied at this stage, allowing a bi-driven control of the entire system.<\/jats:p>","DOI":"10.2478\/v10006-012-0033-6","type":"journal-article","created":{"date-parts":[[2012,6,29]],"date-time":"2012-06-29T14:49:17Z","timestamp":1340981357000},"page":"437-448","source":"Crossref","is-referenced-by-count":10,"title":["Hand gesture recognition based on free-form contours and probabilistic inference"],"prefix":"10.61822","volume":"22","author":[{"given":"W\u0142odzimierz","family":"Kasprzak","sequence":"first","affiliation":[]},{"given":"Artur","family":"Wilkowski","sequence":"additional","affiliation":[]},{"given":"Karol","family":"Czapnik","sequence":"additional","affiliation":[]}],"member":"37438","reference":[{"issue":"2","key":"1","doi-asserted-by":"crossref","first-page":"174","DOI":"10.1109\/78.978374","article-title":"A tutorial on particle filters for online nonlinear\/non-Gaussian Bayesian tracking","volume":"50","author":"M.
