    Using Differential Constraints to Generate a 3D Face Model from Stereo

    We propose a way to incorporate a priori information in a 3D stereo reconstruction process from a pair of calibrated face images. A 3D mesh modeling the surface is iteratively deformed in order to minimize an ...

    Two methods for a reliable corner detection in 2D images

    In this paper, we apply successively two methods for corner detection in two-dimensional images, i.e. a differential geometrybased approach relying on multi-scale curvature computation and curvature extrema ex...
