Increasingly, models of the world are directly built from images. The paper discusses a number of recent developments that try to push the enveloppe of what image-based modeling can achieve. In particular, the analysis of 3D surface deformations is discussed for face animation, the extraction of matches under wide baseline conditions for 3D scene reconstruction, and the synthesis of viewpoint dependent textures for realistic object rendering. 1 Image-based modeling During the last few years, low-cost and user-friendly solutions for 3D modeling have become available. Shapefrom-video [13, 23, 12] extracts 3D shapes and their textures from video sequences as the only input. One-shot structured light techniques [33, 24] get such information from a single image, but need the projection of a special pattern. These techniques have the advantage that they are cheaper than traditional solutions like dedicated multicamera rigs or laser scanners, as they only require off-theshelf hardware. Moreo...
