Lakshminarayanan","doi":"10.1109/SSST.1993.522835","DOIUrl":"https://doi.org/10.1109/SSST.1993.522835","url":null,"abstract":"Methods for determining the three-dimensional (3-D) form of complex objects in a scene from a pair of images using the principles of stereo vision are described. A pair of stereo images are epipolar- or raster-scan-aligned to restrict the search to one dimension along the horizontal lines as a first step in location of image feature points. A correlation window of size 5/spl times/5 around a pixel on the left image is superimposed on a similar window centered around every pixel along the same scan line of the right image. A normalized cross-correlation value for every pair of windows is determined. The image points in the right image which give the maximum correlation value are chosen as the corresponding points for the associated points in the left image. Once the corresponding points are found, the disparity is determined. This initial disparity map is noisy. A smoothing or interpolation algorithm has been developed, greatly increasing the number of feature points that can be identified. Sobel Edge detection is employed to locate discontinuities. Disparity values at edge points are added back into the smoothed disparity map, and the modified smoothed disparity map is used for 3-D rendering.","PeriodicalId":260036,"journal":{"name":"1993 (25th) Southeastern Symposium on System Theory","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127800666","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Neural network identification (NNI) is used to obtain a dynamic model of a flexible joint robot to be controlled. Once NNI has closely matched the dynamic model of a flexible joint robot, neural network control (NNC) of tracking trajectory of a flexible joint robot is designed. Both tasks are completed using the backpropagation neural network. The method is shown to be a more simple, robust and adaptive learning control system than traditional control design for tracking control of a flexible joint single-link robot.","PeriodicalId":260036,"journal":{"name":"1993 (25th) Southeastern Symposium on System Theory","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123724314","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Given spectral estimates of the SSME test data and the poles of the system, RID calculates a model of the spectral quantities using a least-squares technique. Application of RID to an SSME spectral estimate is shown. RID is also modified to use constrained least squares (CLS) instead of least squares. This technique is used to obtain models which more tightly fit the data within a user specified frequency range. A contrived example using RID with CLS is included to illustrate the advantages of using this method.","PeriodicalId":260036,"journal":{"name":"1993 (25th) Southeastern Symposium on System Theory","volume":"172 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122049713","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The company's management analyzes these reports for the ultimate purpose of meeting their customers' needs and forecasting future production demands. Inherently, the developed applications promote efficiency and productivity within the workplace. This is apparent as less time is spent by an employee in accumulating the necessary information to produce various reports. In doing so, more time is spent by the employee in performing other tasks that can further enhance a company's net value. The real power of these software applications lies in their ability to create intelligent graphical user interfaces (GUIs), utilizing object-oriented visual programming tools.","PeriodicalId":260036,"journal":{"name":"1993 (25th) Southeastern Symposium on System Theory","volume":"194 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122385340","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
