    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (26 KB)

    Summary form only given, as follows. An alternative to the classical method filter, namely the phase-only filter, is shown to be useful for pattern recognition and image correlation. It exhibits extremely narrow correlation peaks with very small sidelobes, better discrimination between similar objects, and 100% throughput when implemented optically. Several alternatives derived from the phase-only... View full abstract»

    Several methods for segmentation of document images are explored. The authors pose the segmentation operation as a statistical classification task with two pattern classes: print and background. A number of classification strategies are available. All require some prior information about the distribution of gray levels for the two classes. Learning (either supervised or unsupervised) and automatic... View full abstract»

  • Straight homogeneous generalized cylinders: analysis of reflectance properties and a necessary condition for class membership

    Publication Year: 1989, Page(s):1260 - 1265 vol.3
    Cited by:  Papers (3)
    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (568 KB)

    Consideration is given to two membership tests for straight homogeneous generalized cylinders to determine if an object in the image is a member of the shape class. It is shown that contour information alone is insufficient to recover a straight homogeneous generalized cylinder uniquely. It is then shown that the sign and magnitude of the Gaussian curvature at a point vary among members of a conto... View full abstract»

    The neuron network in the inner catfish retina was studied by injecting current from the one neuron and recording resulting responses into a nearby neuron. Current injected into an amacrine or a ganglion cell always produced a response from neighboring amacrine or ganglion cells chosen randomly. Bidirectional communications were found to exist for neurons of similar response patterns, e.g. on-cell... View full abstract»

    Determinants of performance in a simulated hover task are examined. This task uses an extremely simplified vehicle model with only three degrees of freedom: longitudinal (fore/aft), lateral (left/right), and vertical (up/down). No rotational motions are simulated. Only one control manipulation is allowed, namely control of vertical craft velocity. The task uses a fixed base simulator with three ad... View full abstract»

    The task of raising a rectangular parallelopiped object on the plane surface to a standing position by a robot manipulator is considered. An initial contact between the object and the surface is assumed to be a point contact. To perform the task, the manipulator needs to be servoed to that the object position changes from a point contact to an edge (line) contact and then to a plane contact, using... View full abstract»

  • The modeling of a neural net as a best input-output map approximation in a generalized Fock space

    Publication Year: 1989
    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (44 KB)

    In filter design theory, one derives the filter structure by requiring that the frequency response of the filter match, in some optimal way, a desired frequency response. A similar philosophy is adopted to derive the architecture of a neural net, except that in this case, because of the nonlinear nature of the neural net, the frequency response can no longer be used as a design criterion. Instead,... View full abstract»

  • Validation of blackboard architecture for dynamic intent inferencing

    Publication Year: 1989, Page(s):35 - 39 vol.1
    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (444 KB)

    The authors propose the concept of an operator's associate to serve as an intelligent aid to the human operator. They note that a necessary prerequisite for a useful and effective `intelligent' automated aid is the ability to understand, or infer the intentions of, the human operator. This ability in turn relies on a sound model of operator performance goals in the control of the system. A good mo... View full abstract»

    It is noted that technology has matured to the point that it should be possible to design automation in ways that support, complement, and extend the capabilities of human operators and, further, to do so in ways ensuring that the person-machine system as a whole can behave with more informational and procedural power, efficiency, and productivity than in early eras when the machine or the person ...

  • Mean field theory and MT neurons

    Publication Year: 1989, Page(s):454 - 458 vol.2
    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (352 KB)

    The problem of obtaining reliable estimates of the optic flow field and its variation is discussed. It is argued that circuitry in the middle temporal (MT) visual area is arranged to provide mean field approximations of the optical flow field, that is, the maximal neighborhood over which the local field can be well-approximated as uniform, parallel translation. In addition, the way the mean field ... View full abstract»

    An optimization approach is used to solve the correspondence problem for a set of features extracted from a pair of stereo images. A cost function is defined to represent the constraints on the solution which is then mapped onto a 2-D neural network for minimization. Each neuron in the network represents a possible match between a feature in the left image and one in the right image. Correspondenc... View full abstract»

    Large-scale management information systems, knowledge-based systems, neural systems, control systems and others are becoming extremely sophisticated. In order to investigate their hierarchical structure the author considers such systems as topological spaces. These systems are partitioned into numerous subsystems, cells or elements in the process of their analysis and design. Such decomposition is... View full abstract»

    Experiments are described that studied how people make team decisions under uncertainty when they second-guess their partner. Subjects were presented with a sequence of targets. They were told that they should shoot at light-weight targets and that their partner would shoot at heavy ones. Target weight was ambiguous, but could be estimated from target size and color. An optimal decision strategy i... View full abstract»

    In a previous publication (1988), the author proposed an algorithm for the parallel evaluation of logic programs from bottom to top in compile time. In this paper the author improves the algorithm, solving some problems not previously discussed. This leads to a reduction of the required storage space and makes the algorithm more practical View full abstract»

    It is suggested that human-factors professionals in large R&D (research and development) organizations should have a centralized human-factors group (or department) with a manager sensitive to human-factors organizational issues. This arrangement permits these professionals to maximize their contributions to the design, development, and testing of a product or service. Managers of human-factor... View full abstract»
