Abstract :
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, biology or medical imaging). Their presence often 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, They also correctly deal with the delicate situations of transparency or partial occlusions.
