    A brief overview is given of techniques for constructing descriptions of 3D solid objects based on active sensing, whereby scene illumination is manipulated by controlling the light source or the imaging geometry. The light source can be controlled to cast light of a certain spatial pattern to reveal the surface structure of imaged objects. The pattern can be a single point, a single line segment,...

    Word directed toward the development of a vision system for bin picking of rigid 3D objects is reported. Any such system must have components for sensing, feature extraction, modeling, and matching. A structured light system which attempts to deliver a rich 2/sup 1///sub 2/D representation of the scene is described. Surface patches are evident as connected sets of stripes whose 3D coordinates are ... View full abstract»

    A knowledge-based shape representation and recognition system that can handle a large class of objects under less constrained situations than required for current machine vision system is proposed. Intelligent integration of different shape representation schemes and generation of the best shape recognition strategy are carried out using global shape properties. The proposed scheme effectively inc... View full abstract»

  • Computational stereo vision using color

    Publication Year: 1988, Page(s):31 - 36
    Cited by:  Papers (16)

    An investigation of the efficiency of color or chromatic information as an aid in solving the stereo correspondence problem is described. Two very simple stereo algorithms differing only in the use of chromatic information are applied to images containing various chromatic characteristics. The intensity-matching algorithm matches the zero crossings in a Laplacian-of-Gaussian filtered image, while ... View full abstract»

    A pilot study that compares vision systems that might be used to control a teleoperated land vehicle is described. The study compares three forward-looking vision systems, both for actual remote driving and for noninteractive video simulation. Remote driving has the advantage of realism but is subject to variability in driving strategies and can be hazardous to equipment. Video simulation provides... View full abstract»

    An online unsupervised feature-extraction method for high-dimensional remotely sensed image data compaction is proposed. This method is directed at the reduction of data redundancy in the scene representation of satellite-borne, high-resolution multispectral sensor data. The algorithm partitions the observation space into an exhaustive set of disjoint objects, and pixels belonging to each object a... View full abstract»

    The application of a procedure for classifying tissue types from unlabeled acoustic measurements using unsupervised analysis is reviewed and evaluated. Unsupervised learning techniques are applied to the problems of detecting tumors within an organ and of discriminating between tissue types of two neighboring organs such as the liver and the kidney.<> View full abstract»

    The fine structure of the human muscle forces that are exerted during the writing of a signature is consistent and well defined for most people. On the basis of this observation, an experimental system that utilizes a person's signature waveform dynamics for identification is proposed. The system is intended to be used for online signature verification. It can successfully verify a person's identi... View full abstract»

    A description is given of research that applies techniques from computer vision to automation of rotorcraft navigation, especially when flying low to avoid detection by an enemy. The effort emphasizes the development of a methodology for detecting the ranges to obstacles in the region of interest based on the maximum utilization of passive sensors. The range map derived from the obstacle detection... View full abstract»
