Self-Calibration and Neural Network Implementation of Photometric Stereo
This paper describes a new approach to neural network implementation of photometric stereo for a rotational object with non-uniform reflectance factor. Three input images are acqu...

Large-Scale Urban Modeling by Combining Ground Level Panoramic and Aerial Imagery
We describe an interactive system that models regions of an urban environment, such as a group of tall buildings. Traditional image-based modeling methods often cannot model such ...

Polygonization of volumetric reconstructions from silhouettes
In this work we propose a method for the polygonization of octree-based reconstructions by dual contouring. Dual contouring is an adaptive method for determining contiguous polygo...

Laplace-Beltrami Eigenfunctions Towards an Algorithm That "Understands" Geometry
One of the challenges in geometry processing is to automatically reconstruct a higher-level representation from raw geometric data. For instance, computing a parameterization of a...

Billboard clouds
We introduce billboard clouds – a new approach for extreme simplification in the context of real-time rendering. 3D models are simplified onto a set of planes with texture and...
