Patch-based potentials for interactive contour extraction

Résumé

The problem of interactive contour extraction of targeted objects of interest in images is challenging and finds many applications in image editing tasks. Several methods have been proposed to address this problem with a common objective: performing an accurate contour extraction with minimum user effort. For minimal paths techniques, achieving this goal depends critically on the ability of the so-called potential map to capture edges. In this context we propose new patch-based potentials designed to have small values at the boundary of the targeted object. To evaluate these potentials, we consider the livewire framework and quantify their abilities in terms of number of needed seed points. Both visual and quantitative results demonstrated the strong capability of our proposed potentials in reducing the user's interaction while preserving a good accuracy of extraction.
