The control and supervisory tasks have been implemented using the blackboard approach to problem solving in which several knowledge sources cooperate, providing a very flexible problem solving framework. The blackboard shell control unit developed in this study uses a dual-level control structure and a comprehensive data structure for the knowledge source descriptors. The modularity of the control and supervisory system allows the control and supervisory strategies to be modified or extended simply by adjoining additional knowledge sources to the existing ones and tuning different knowledge source descriptors.<<ETX>>","PeriodicalId":72691,"journal":{"name":"Conference proceedings.

The novelty of the filter is that its region of support is tuned simultaneously in its size and orientation. An edge strength measure is extracted from the local variance and used to control the size of the window. The gradient direction is used to adapt the orientation of the window. The use of both edge strength and edge detection information allows large windows to be used even in the vicinity of edges. The filter has been tested for additive white Gaussian noise with the mean as the point estimator over local windows, and for additive white impulse noise with the median as the point estimator. Results, particularly for the adaptive median filter, are very promising. The results show that the filter does greater smoothing in the vicinity of edges without compromising performance away from edges and the edge structure of the image.<<ETX>>","PeriodicalId":72691,"journal":{"name":"Conference proceedings.

A highly-directional ultrasonic distance ranging device is utilized to measure features of interest in the workspace of the robot arm. Off-line trajectory planning is combined with online motion guidance by the supervisory controller to formulate and execute the desired path movement. In a demonstration application, the vertical distance from a workpiece surface was measured and utilized to perform online trajectory adjustment for the robot cutting-tool motion. This makes it possible to compensate for factors such as robot performance limitations, inaccurate fixturing and inexact object location. The hardware implementation and control strategy used to provide verification of the concept are presented, along with the experimental results achieved.<<ETX>>","PeriodicalId":72691,"journal":{"name":"Conference proceedings.

The results showed a response time advantage for the graph that depended on the type of task performed. For tasks which involved simply verifying that a given frame existed or verifying a direct relationship between two frames, use of the list and graph resulted in about equal response time. For tasks which involved verifying indirect relationships between frames, or verifying that a particular frame occurred in a navigational pathway between two other frames, the graph was much faster than the list. The magnitude of the advantage depended on the number of direct relationships that had to be navigated to perform the task; the more the direct relationships that had to be navigated, the greater was the advantage for the graph. These results suggest that the relationships between frames should be presented to users as a graph.<<ETX>>","PeriodicalId":72691,"journal":{"name":"Conference proceedings.

Rather than identifying boundaries between texture patches, this method detects regions of uniform texture in real images. No a priori knowledge regarding the image, the texture types, or their scales is assumed. The images may contain an unknown number of texture regions including regions with no texture at all. The method is most useful for identifying textures in which sharp intensity changes constitute the most distinctly perceived characteristic. Texture features are computed over image subregions from the distributions of local orientations and the separations of zero-crossing points. The segmentation algorithm establishes the existence of texture regions by finding neighboring subregions that share one or more nonaccidental properties of the computed features, e.g., a distribution of local orientations with a significant peak. Regions' accurate boundaries are identified by extending the seed regions using a region-growing technique that is applied to the computed texture features. The growth is directed by a region-specific self-adaptive thresholding scheme. No assumption is made regarding the texture scale, and the feature analysis is performed across multiple neighborhood (window) sizes. As a result different textures in the image may be segmented using different window sizes.<<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.
