    An attempt is made to demonstrate the feasibility of defining an object category in terms of the functional properties shared by all objects in the category. This form of representation should allow much greater generality. A complete system has been implemented that takes the boundary surface description of a 3D object as its input and attempts to recognize whether the object belongs to the categ...

  • Recognition by linear combinations of models

    An approach to visual object recognition in which a 3D object is represented by the linear combination of 2D images of the object is proposed. It is shown that for objects with sharp edges as well as with smooth bounding contours, the set of possible images of a given object is embedded in a linear space spanned by a small number of views. For objects with sharp edges, the linear combination repre... View full abstract»

    Invariant descriptors are shape descriptors that are unaffected by object pose, by perspective projection, or by the intrinsic parameters of the camera. These descriptors can be constructed using the methods of invariant theory, which are briefly surveyed. A range of applications of invariant descriptors in 3D model-based vision is demonstrated. First, a model-based vision system that recognizes c... View full abstract»

  • Robot vision using a feature search strategy generated from a 3D object model

    A robot vision system that automatically generates an object recognition strategy from a 3D model and recognizes the object using this strategy is presented. The appearance of an object from various viewpoints is described in terms of visible 2D features such as parallel lines and ellipses. Features are then ranked according to the number of viewpoints from which they are visible. The rank and fea... View full abstract»

  • An optimal sensing strategy for recognition and localization of 3D natural quadric objects

    An optimal sensing strategy for an optical proximity sensor system engaged in the recognition and localization of 3D natural quadric objects is presented. The optimal sensing strategy consists of the selection of an optimal beam orientation and the determination of an optimal probing plane that compose an optimal data collection operation known as an optimal probing. The decision of an optimal pro... View full abstract»

  • Context-based vision: recognizing objects using information from both 2D and 3D imagery

    Results from an ongoing project concerned with recognizing objects in complex scene domains, especially in the domain that includes the natural outdoor world, are described. Traditional machine recognition paradigms assume either that all objects of interest are definable by a relatively small number of explicit shape models or that all objects of interest have characteristic, locally measurable f...

  • An integrated approach to 3D motion analysis and object recognition

    An integrated system for 3D motion estimation and object recognition with outdoor stereo image sequences as inputs is presented. The goals are to obtain from input stereo images the 3D motion description and the identification of a vehicle moving against a stationary background. In order to accomplish the desired goals, the system consists of four stages; motion estimation, distinctive feature ext... View full abstract»

  • Space and time bounds on indexing 3D models from 2D images

    Model-based visual recognition systems often match groups of image features to groups of model features to form initial hypotheses, which are then verified. In order to accelerate recognition considerably, the model groups can be arranged in an index space (hashed) offline such that feasible matches are found by indexing into this space. For the case of 2D images and 3D models consisting of point ... View full abstract»

    The authors attempt to determine what can be inferred from ambiguity in processes of visual interpretation. They discuss this question in a specific context: the interpretation of scene geometry in the form of parametrized volumetric models. Ambiguity is described as a local probabilistic property of the misfit error surface in the parameter space of superellipsoid models, namely, as an ellipsoid ... View full abstract»

  • BONSAI: 3D object recognition using constrained search

    BONSAI, a model-based 3D object recognition system, is described. It identifies and localizes 3D objects in range images of one or more parts that have been designed on a computer-aided-design (CAD) system. Recognition is performed via constrained search of the interpretation tree, using unary and binary constraints (derived automatically from the CAD models) to prune the search space. Attention i...
