Abstract
An algorithm is described that can track edges determined by the Lapla cian of Gaussian operator from low to high resolution. The algorithm d oes not require a precomputed scale step size, but rather determines t he step size adaptively by using the image content. A binary search is carried out to find the topology of the scale-space image, which is t hen used to track the edges. The proposed algorithm guarantees correct edge tracking with step sizes considerably larger than has been previ ously used.
