  • Polarization-based shadow detection
    Publication number: 20080303891
    Abstract: In a first exemplary embodiment of the present invention, an automated, computerized method is provided for determining an illumination flux condition in a scene. The method comprises the steps of generating and storing a sequence of images of the scene, each one of the sequence of images comprising an array of pixels and corresponding to the scene photographed in a preselected polarization direction, different from the polarization direction of other ones of the sequence of images, determining a polarization sequence vector for at least one pixel in the array, as a function of color information for the pixel in the array, among the sequence of images; and utilizing the polarization sequence vector to determine one of a shadowed and lit illumination condition for the at least one pixel.
