The image to be coded is first clustered into a small subset of neighboring images and then the neural network-based encoder is used to find the best matching code sequences in the codebook. This subset is then used as a candidate set and an exhaustive search is then performed within this subset to find an optimal code sequence which minimizes the perceptual error between coded and decoded images. In this work, a generic codebook is developed using non-causal differential pulse coded modulation (DPCM) with residual mean removal and vector quantization using Linde, Buzo and Gray (1980) method. The codebook is analyzed to identify a pattern in the codebook. This pattern is used to train a neural network to obtain the approximate index of the pattern in the codebook. Then, an extensive search is done around this approximate position identified by the neural network to obtain the nearest neighbor of the pattern. Since the candidate set is usually much smaller that the whole code book, there is a substantial saving in codebook search time for coding an image as compared to the traditional method using full codebook search by the LBG algorithm.","PeriodicalId":206022,"journal":{"name":"Proceedings of the IEEE SoutheastCon 2000.

The CAD tool specifically supports manual and semi-automatic routing for the Cypress Delta 39 K series CPLD for the purpose of manufacturing testing of the programmable interconnect network within the device as well as all programmable logic functions. Two routing algorithms were developed and proved to work correctly with the best one chosen based on complexity analysis. The resultant router CAD tool supports all CPLDs in the Delta 39 K series family and produces the configuration bits necessary to program or configure the CPLD for the extensive tests that must be applied to ensure that the manufactured CPLDs are defect-free. The router has also been used extensively in the verification portion of the design process of the Delta 39 K series CPLDs. While the router is specific to a particular CPLD, the basic approach, including features and algorithms, is applicable to any CPLD or FPGA where programmable routing resources must be specified to accurately test the device and provide design verification.","PeriodicalId":206022,"journal":{"name":"Proceedings of the IEEE SoutheastCon 2000.

This problem is further complicated for a system with multiple robots navigating a common terrain. The paper describes a field-capable system for navigation, obstacle avoidance, simulated visual training of mobile robots, group world perception modeling using visual feedback from multiple robots, and fusion of sonar range data with vision information for the purpose of terrain learning. A neural network approach is proposed for fusion of the robots visual feedback. In this approach, each mobile robot is presumed to be equipped with one camera and sonar sensor. In the proposed technique, self-localization of the robots and localization of obstacles are performed based on the visual and sonar feedback from the neural network. Computer simulation of the technique is done with FMCell simulation software an interactive graphical simulation environment. Results of simulation runs illustrating the capabilities of this technique are provided. The technique provides a better and simplified approach for visual servoing of a multi-agent system.","PeriodicalId":206022,"journal":{"name":"Proceedings of the IEEE SoutheastCon 2000.

One situation where this may occur is when templates or training vectors arise from images acquired at one range, and the image under question has been acquired at a multiple of this range. Here one could scale the template accordingly before beginning to scan the scene. Another application is where the template and scene are at the same range, but their dimensions are so great as to make the scanning process overly burdensome computationally. Here one could scale both the template and scene by the same factor before scanning to reduce the number of computations. The results of this coarse-resolution scan would then give starting points and neighborhoods for finer-resolution scans. For either of these applications, if there is pixel misalignment of the scene compared to the template, then an error is introduced and the measure of closeness of match is degraded. This is caused by the fact that the boundaries over which the pixel averaging is performed may be different for the scene than for the template. The impact of such misalignment is investigated here. An analytical expression for this effect is obtained and a means is presented for evaluating it based on the template alone, without knowledge of the scene to be scanned. Simulations are performed to test the methodology.","PeriodicalId":206022,"journal":{"name":"Proceedings of the IEEE SoutheastCon 2000. 'Preparing for The New Millennium' (Cat.
