Abstract: Embodiments of the invention include a method and/or system for determining the relative location of light sources in a video clip. The relative location of a light source can be determined from information found within the video clip. This can be determined from specular reflection on a planar surface within the video clip. An ellipse can be fit to glare that is indicative of specular reflection on the planar surface. An outgoing light angle can be determined from the ellipse. From this outgoing light angle, the incident light angle can be determined for the frame. From this incident light angle, the location of the light source can be determined.

Abstract: Systems and methods are discussed to separate the specular reflectivity and/or the diffuse reflectivity from an input image. Embodiments of the invention can be used to determine the specular chromaticity by iteratively solving one or more objective functions. An objective function can include functions that take into account the smooth gradient of the specular chromaticity. An objective function can take into account the interior chromatic homogeneity of the diffuse chromaticity and/or the sharp changes between chromaticity. Embodiments of the invention can also be used to determine the specular chromaticity of an image using a pseudo specular-free image that is calculated from the input image and a dark channel image that can be used to iteratively solve an objective function(s).
