Abstract. Brightness values of pixels in an image are related to image irradiance by a non-linear function, called the radiometric response function. Recovery of this function is i...
Different materials reflect light in different ways, and reflectance
interacts with shape, lighting, and viewpoint to
determine an object’s image. Common materials exhibit dive...

We present a completely automatic method for obtaining the approximate calibration of a camera (alignment to a world frame and focal length) from a single image of an unknown scene...
By using mirror reflections of a scene, stereo images can be captured with a single camera (catadioptricstereo). Single camera stereo provides both geometric and radiometric advan...
In this paper, parallelepipeds and their use in camera calibration and 3D reconstruction processes are studied. Parallelepipeds naturally characterize rigidity constraints present...
