Issue Date: | 2003 | Journal: | Pattern Recognition | Abstract: | This paper proposes a new model for contour deformations using wavelets. This model uses Sobolev spaces to control the smoothness of the contour deformation. This formulation defines a probabilistic model that induces a prior distribution for contour deformation. Based on this distribution, the fitting problem is solved in Bayesian terms. The deformation model is also used to generate a prior dynamic model for contour evolution in time. This probabilistic model is then applied to solve the tracking problem. Computational results for several real-image problems are given for both the Kalman and condensation filters. | URI: | http://hdl.handle.net/10553/73288 | ISSN: | 0031-3203 | DOI: | 10.1016/S0031-3203(02)00168-1 | Source: | Pattern Recognition [ISSN 0031-3203], v. 36 (5), p. 1119-1130, (Mayo 2003) |
