PARVO, a computervision system that addresses the problems of fast and generic recognition of unexpected 3D objects from single 2D views, is introduced. Recently, RBC (recognition by components), a new human image understanding theory, has been proposed on the basis of the results of various psychological studies. However, no systematic computational evaluation of its many aspects has been reported yet. The object recognition system the authors have built is a first step toward this goal, since its design respects and makes explicit the main assumptions of the proposed theory. It analyzes single-view 2D line drawings of 3D objects typical of the ones used in human image understanding studies. The main issues related to generic object recognition are discussed, original algorithms and techniques specific to the author's systems are described, and results of the different processing stages of the system are presented.< >
In numerous computervision applications, there is both the need and the ability to access multiple types of information about the three dimensional aspects of objects or surfaces. When this information comes from dif...

The proceedings contain 81 papers. The topics discussed include: object identification and orientation estimation from contours based on an affine invariant curvature;recognizing and locating objects using partial object description generated by feature extraction by demands;morphological shape representation and recognition of binary images;frequency domain characterization of synthetic discriminant functions;vision guided intelligent robot design and experiments;the digital morphological sampling theorem;new algorithms for automated symmetry recognition;localized noise propagation effects in parameter transforms;an experimental system for the integration of information from stereo and multiple shape from texture algorithms;and discriminating textured surfaces in natural imagery.
New methods of image matching and of calculation of the affine transformation relating two images of an object in different orientations are developed. These methods are applicable to contours extracted from images of...
