    • The Alignment of Objects with Smooth Surfaces 

      Ullman, Shimon; Basri, Ronen (1988-07-01)
      This paper examines the recognition of rigid objects bounded by smooth surfaces using an alignment approach. The projected image of such an object changes during rotation in a manner that is difficult to predict. A ...
    • The Alignment of Objects With Smooth Surfaces: Error Analysis of the Curvature Method 

      Basri, Ronen (1991-11-01)
      The recognition of objects with smooth bounding surfaces from their contour images is considerably more complicated than that of objects with sharp edges, since in the former case the set of object points that generates ...
    • Distance Metric Between 3D Models and 3D Images for Recognition and Classification 

      Basri, Ronen; Weinshall, Daphna (1992-07-01)
      Similarity measurements between 3D objects and 2D images are useful for the tasks of object recognition and classification. We distinguish between two types of similarity metrics: metrics computed in image-space (image ...
    • Extracting Salient Curves from Images: An Analysis of the Saliency Network 

      Alter, T.D.; Basri, Ronen (1995-08-01)
      The Saliency Network proposed by Shashua and Ullman is a well-known approach to the problem of extracting salient curves from images while performing gap completion. This paper analyzes the Saliency Network. The ...
    • Localization and Positioning Using Combinations of Model Views 

      Rivlin, Ehud; Basri, Ronen (1992-09-01)
      A method for localization and positioning in an indoor environment is presented. The method is based on representing the scene as a set of 2D views and predicting the appearances of novel views by linear combinations ...
    • On The Uniqueness of Correspondence Under Orthographic and Perspective Projections 

      Basri, Ronen (1991-12-01)
      The task of shape recovery from a motion sequence requires the establishment of correspondence between image points. The two processes, the matching process and the shape recovery one, are traditionally viewed as independent. ...
    • Recognition by Linear Combinations of Models 

      Ullman, Shimon; Basri, Ronen (1989-08-01)
      Visual object recognition requires the matching of an image with a set of models stored in memory. In this paper we propose an approach to recognition in which a 3-D object is represented by the linear combination of 2-D ...
    • Recognition by Prototypes 

      Basri, Ronen (1992-12-01)
      A scheme for recognizing 3D objects from single 2D images is introduced. The scheme proceeds in two stages. In the first stage, the categorization stage, the image is compared to prototype objects. For each prototype, ...
