Since the integration of normal vectors plays an important role for reconstructing a surface, over decades it has been one of the most fundamental problems in computer vision and thereby extensively investigated by many researchers [6]. While many schemes have been proposed, there is, however, still a need for methods that combine accuracy, robustness and(More)
We present a new, massively parallel method for high-quality multiview matching. Our work builds on the Patch-match idea: starting from randomly generated 3D planes in scene space, the best-fitting planes are iteratively propagated and refined to obtain a 3D depth and normal field per view, such that a robust photo-consistency measure over all images is(More)
In the last four decades there has been enormous progress in Shape from Shading (SfS) with respect to both modelling and numerics. In particular approaches based on advanced model assumptions such as perspective cameras and non-Lambertian surfaces have become very popular. However, regarding the positioning of the light source, almost all recent approaches(More)
