|| AN ACTIVE CONTOUR METHOD BASED ON WAVELET FOR TEXTURE BOUNDARIES|
||Thomas Corpetti; CNRS - Univ. Rennes 2|| |
|| In this paper, we present an active contour method able to capture texture boundaries. To that end, an external potential term based on wavelet coefficients is defined. The proposed approach only deals with boundaries to be able to detect particular patterns which are identifiable only through a texture border. Such patterns, which cannot be treated like traditional objects, appear in many natural images (meteorology, ...). Their presence inform about a particular phenomena in the observed scene and the detection of such structures is hence of primary interest. The different bands of wavelet coefficients enable to characterize the desired texture and also correctly deal with the delicate situations of transparency or partial occlusions.|
