A Fast Level-Set Method for Accurate Tracking of Articulated Objects with an Edge-Based Binary Speed Term

Cristina Darolti, Alfred Mertins, Ulrich G. Hofmann

Abstract

This paper presents a novel binary speed term for tracking objects with the help of active contours. The speed, which can be 0 or 1, is determined by local nonlinear filters, and not by the strength of the gradient as is common for active contours. The speed has been designed to match the nature of a recent fast level-set evolution algorithm. The resulting active contour method is used to track objects for which probability distributions of pixel intensities for the background and for the object cannot be reliably estimated.
