In this system, an object is modeled using only a small number of 2D distinct perspective views (standard views) predefined wit the help of markers placed on the object. During the recognition process, a standard view is acquired by first determining its surface normal (standard-view axis), and then aligning the camera's optical axis with it. Standard-view axes are obtained by analyzing the images of the markers. A morphological skeleton transform (MST) is used for the extraction of required marker features. This work presents the analytical solution for the two proposed premarking schemes, based on circular markers, that can be used in acquiring standard views of objects. Specific issues addressed include: the determination of the perspective distortion and its relative importance, the determination of the transformation parameters required for camera alignment, and the use of a class of MST, pseudo-Euclidean skeletons, for feature extraction.<<ETX>>","PeriodicalId":72691,"journal":{"name":"Conference proceedings.

Computational efficiency is a primary problem in implementing any practical system. In order to improve computational efficiency, several methods have been proposed to exploit the parallelism inherent in reasoning under uncertainty. However, some of these models can be used only in the case of singly connected networks, and one allows only one direction of reasoning. A parallel reasoning method based on the minimum cross entropy principle and the concept of recursive causal models is proposed to avoid the disadvantages of the methods.<<ETX>>","PeriodicalId":72691,"journal":{"name":"Conference proceedings.

GT-FMS, a real-time simulator of an FMS, was implemented with data from an actual FMS installation. An experiment was conducted in which humans interacted with the control system of GT-FMS at an aggregate level. The humans described each of their control actions, and their decision processes were evaluated by mapping these descriptions onto a standard model of human decision-making. The experimental results support making humans an integral part of the FMS control process, since an intricate knowledge of the system state and system sensitivity were crucial to human decision-making in GT-FMS. Humans in this experiment used detailed system status information, rather than system performance history, as the basis of their control decisions and were inconsistent in defining their goals.<<ETX>>","PeriodicalId":72691,"journal":{"name":"Conference proceedings.

These communications are mutually excitatory, fast, and likely linear.

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 contour-equivalent class. Next, a method of ruling straight homogeneous generalized cylinder images is developed. This ruling of the surface serves two functions. First, the ruling algorithm provides a heuristic test of whether or not the image is consistent with that of a straight homogeneous generalized cylinder. Secondly, the ruling makes explicit certain parameters of the underlying straight homogeneous generalized cylinder that the authors use in their second membership test. The second membership test is an intensity-based method which assumes that the surface has geodesics and that the albedo is constant. The method compares intensity values at corresponding meridian points along cross-sectional geodesics.<<ETX>>","PeriodicalId":72691,"journal":{"name":"Conference proceedings.

The position estimation is based on analysis of landmarks being detected by a TV-camera attached to the mobile system. The difference between the known real shape of the landmark and its image provides the information necessary for determining the relative position of the mobile system to the landmark. The parameters of the landmark image are extracted at high speed using an optical processor that performs an optical Hough transform, while the coordinates of the mobile system are computed from these parameters in a digital coprocessor using fast and simple algorithms. Different sources of errors have been analyzed, and algorithms to improve the performance of the mobile system have been developed and evaluated by computer simulation.<<ETX>>","PeriodicalId":72691,"journal":{"name":"Conference proceedings.

To use these methods properly, it is necessary first to establish that the structure of the system under study belongs to one of the broad structural classes examined; such a priori constraints would generally be inferred from the known anatomical and physiochemical properties of the system. Using the methods presented, input-output measurements are used to restrict the structural classification of the system further and to estimate the parameters of the classified model. Ongoing efforts to identify the spatiotemporal nonlinear networks that underlie the extracellularly recorded (spike) responses of visual cortical neurons to photic stimulation are discussed.<<ETX>>","PeriodicalId":72691,"journal":{"name":"Conference proceedings.
