Estimation of Multiple Objects at Unknown Locations with Active Contours
Abstract. This paper presents an algorithm for the estimation of multiple regions with unknown shapes and positions using multiple active contour models (ACM’s). The algorithm organizes edge points into strokes and computes the association between those strokes and the ACM’s using the component wise EM algorithm (CEM) for MAP estimation. The algorithm is randomly initialized with a high number of ACM’s and performs online model selection using importance sampling. Experimental results show the effectiveness of the proposed technique.
