Abstract: In this study we address the problem of recovering region boundary patterns consistent with a given pattern. A level set method formulated in the variational framework evolves an active contour towards regions of interest boundaries while omitting the others. The curve evolution results from the minimization of a functional which measures the similarity between the distribution of an image-based geometric feature on the curve and a model distribution. The corresponding curve evolution equation can be viewed as a geodesic active contour flow having a variable stopping function. This affords a global representation of the objects boundaries which can effectively drive active curve segmentation in a variety of otherwise adverse conditions. We ran several experiments supported by quantitative performance evaluations using various examples of segmentation and tracking.
