    Three-dimensional morphable models of objects classes are a powerful tool in modeling, animation and recognition. We introduce the new concept of regularized 3D morphable models, along with an iterative learning algorithm, by adding in the statistical model a noise/regularization term which is estimated from the examples set. With regularized 3D morphable models we are able to handle missing infor... View full abstract»

    It is common experience for human vision to perceive full 3D shape and scene from a single 2D image with the occluded parts "filled-in" by prior visual knowledge. We represent prior knowledge of 3D shapes and scenes by probabilistic models at two levels - both are defined on graphs. The first level model is built on a graph representation for single objects, and it is a mixture model for both man-... View full abstract»

    Based on high-level geometric knowledge, especially symmetry, imposed upon objects in images, we demonstrate how to edit images in terms of correct 3-D shape and relationships of the objects, without explicitly performing full 3-D reconstruction. Symmetry is proposed as the central notation that unifies both conceptually and algorithmically all types of geometric regularities such as parallelism, ... View full abstract»

    Deformable 3-D models can be represented either as explicit or implicit surfaces. Explicit surfaces, such as triangulations or wire-frame models, are widely accepted in the computer vision and computer graphics communities. However, for automated modeling purposes, they suffer from the fact that fitting to 2-D and 3-D image-data typically involves minimization of the Euclidean distance between obs...

  • Reconstruction of objects with jagged edges through Rao-Blackwellized fitting of piecewise smooth subdivision curves

    In some applications objects are known to have non-smooth or "jagged" edges, which are not well approximated by smooth curves. We use subdivision curves as a simple but flexible curve representation, which allows tagging corners to model non-smooth features along otherwise smooth curves. A Markov chain Monte Carlo approach yields an approximate posterior distribution over tags, while Rao-Blackwell... View full abstract»

    A theory and low computational cost linear algorithm is presented for estimating algebraic surfaces of second degree for representing an object in 3D, based on fitting in the dual space (space of tangent planes) computed from images taken by a calibrated camera in a number of positions. The approach and algorithm are designed to handle implicit quadric surfaces, which are regular or singular, in a... View full abstract»

    Modeling and visualization of city scenes is important for many applications including entertainment and urban mission planning. Models covering wide areas can be efficiently constructed from aerial images. However, only roof details are visible from aerial views and ground views are needed to provide details of the building facades for high quality fly-through visualization or simulation applicat...

    A method is presented for automatically extracting key frames from an image sequence. The sequence is divided into clusters of frames with similar appearance, and the most central frame in each cluster defines a key frame. Clustering is done using an extension of the normalized cut segmentation technique based on the inter-frame similarities. The similarity between every pair of frames in the sequ...

    Model-based reconstruction methods are applied to the detailed reconstruction of buildings from close-range images. The 3D points obtained through image matching are segmented into a coarse polyhedral model with a robust regression algorithm, then the geometry of this model is refined with predefined shape templates in order to automatically recover a CAD-like model of the building surface.

    Man-made environments possess many regularities which can be efficiently exploited for image based rendering as well as robotic visual navigation and localization tasks. In this paper we present an approach for automatic extraction of dominant rectangular structures from a single view and show how they facilitate the recovery of camera pose, planar structure and matching across widely separated vi...
