    The authors outline their approach for automatic translation of geometric entities produced by a CAD system into a relational graph structure. They have developed a system which uses 3-D object descriptions created on a commercial CAD system and expressed in the industry-standard IGES form, and performs geometric inferencing to object a relational graph representation of the object which can be st...

    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»

    A method for calibrating ultrasound and video sensors in the hostile underwater environment is presented. It yields sufficient accuracy to allow transformation of image data in one sensor's image plane to the baseframe, and from there into the other sensor's image plane, a prerequisite for any form of sensor fusion. The feasibility of automatic segmentation of underwater video scenes in combinatio... View full abstract»

    Information integration is a driving force underlying many major efforts in manufacturing systems, ranging from MRP and MRP II to the current research on CIM. The problem of integration, however, has not been sufficiently studied previously from the perspective of information. The authors analyze the information aspects of the evolution of integrating manufacturing planning with its control. A con... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (360 KB)

    Pathological behavior of some recently proposed neural net models is shown to depend on how the similarity is defined. The obvious binary interconnection schemes using weights of (1.0) or (+1, M-1) are shown to give unsatisfactory performance for certain types of stored objects, for instance objects that are subsets of other objects, or for certain types of input distortions. The modified... View full abstract»

    Ground target head-tracking performance is used to empirically specify limits of gaze control during passive flight in a virtual world. The data indicate that head-tracking error is related directly to total angular velocity of the target. Simulation modeling of the optic flow demonstrates the differences between conventional optic flow with a fixed gaze and differential optic flow with a tracking... View full abstract»

    Future space servicing operations may involve manually controlled manipulation from a free-flying platform; direct control of such a free-flying telerobot will impose a large workload on the operator. In order to reduce the workload on the human operator, a supervisory control strategy is developed where the operator only controls the end effector, rather than specifying the motion of the entire v...

    Two approaches to the resolution of judgements of an expert team are contrasted. In 1987, the government of Finland appointed a committee of experts from various disciplines to study the social and environmental effects and risks of energy production. The committee used both a decision-analytic approach to the task, where risks of different alternatives were structured through a computer-supported... View full abstract»

    Dexterous grasps for multifingered robot hands are planned. A real-time, joint space finger path planning algorithm is derived for the enclosure phase of grasping motion. The algorithm minimizes the impact momentum of the hand. It uses a preshape Jacobian matrix to map task-level hand preshape requirements into kinematic constraints. A master-slave scheme avoids inter-finger collisions and reduces... View full abstract»

    A method is presented to detect curvilinear structures in 2D images. The approach is based on a generalization of the Hough transform that is different from its traditional, template-based generalizations. With this method, global interaction of edge elements is reduced through the use of the Delaunay graph in utilizing the Hough transform. The algorithm as it is currently implemented needs to be ...

    It is argued that one of the problems associated with contemporary rule-based decision-support systems is that it is not always practical to specify completely a consistent set of decision rules. However, in these cases it is often possible to specify qualitative features (including constraints) and a performance critique for use in the genetic evolution of a consistent set of decision rules.
