1 Henderson, Thomas C.2-D scene analysis using split-level relaxationWe present a new method for applying multiple semantic constraints based on discrete relaxation. A separate graph is maintained for each constraint relation and used in parallel to achieve a consistent labeling. This permits both local and global analysis without recourse to complete graphs. Here l...Discrete relaxation; Split-level relaxation1985
2 Bhanu, Bir3-D model building for computer visionThis paper presents a Computer-Aided Geometric Design (CAGD) based approach for building 3-D models which can be used for the recognition of 3-D objects for industrial machine vision applications. The objects are designed using the Alpha_1 CAGD system developed at the University of Utah. A new metho...CAGD; 3-D models; Machine vision1985
3 Cohen, ElaineA new local basis for designing with tensioned splinesRecently there has been a great deal of interest in the use of "tension" parameters to augment control mesh vertices as design handles for piecewise polynomials. A particular local cubic basis called p-splines, which has been termed a "generalization of B-splines", has been proposed as an appropriat...Tensioned splines1985
4 Mathews, V. JohnAn efficient algorithm for lattice filter/predictorABSTRACT An efficient method for updating the lattice filter/predictor coefficients using the sign algorithm is introduced. The pertinent coefficients are updated using only the signs of the estimation errors at each stage. This method requires less number of multiplications than other adaptive la...1985
5 Mathews, V. JohnAnalysis of the short-time unbiased spectrum estimation algorithmAbstract- The short-time unbiased spectrum estimation (STUSE) algorithm is analyzed and expressions for the mean and variance of the spectrum estimates are derived. The STUSE algorithm deliberately adds biased spectrum estimates in order to yield unbiased estimates and at the same time have excellen...1985
6 Henderson, Thomas C.Arc and path consistency revisitedMackworth and Freuder have analyzed the time complexity of several constraint satisfaction algorithms [4]. We present here new algorithms for arc and path consistency and show that the arc consistency algorithm is optimal in time complexity and of the same order space complexity as the earlier algor...Arc consistency; Path consistency; Constraint satisfaction algorithms1985
7 Henderson, Thomas C.; Bhanu, BirCAGD based 3-D visual recognitionA coherent automated manufacturing system needs to include CAD/CAM, computer vision, and object manipulation. Currently, most systems which support CAD/CAM do not provide for vision or manipulation and similarly, vision and manipulation systems incorporate no explicit relation to CAD/CAM models. CAD...Object manipulation; CAGD1985
8 Lawton, Evert C.Development of guidelines for construction control of pile driving and estimation of pile capacityThe work upon which this report is based was supported by the Washington State Department of Transportation and the U. S. Department of Transportation, Federal highway Administration.1985
9 Henderson, Thomas C.The importance of unknows in Epidemiologic studies1. Epidemiologic study data often include omitted/unobtainable responses (unknowns). In most cases, unknowns are eliminated during data-reduction to facilitate analysis. We examined the effect that elimination of unknowns would have on mortality calculations using data on newborns admitted to a newb...Unknowns; Mortality calculations1985
10 Sikorski, KrisOptimal solution of nonlinear equationsWe survey recent worst case complexity results for the solution of nonlinear equations. Notes on worst and average case analysis of iterative algorithms and a bibliography of the subject are also included.1985
11 Stringfellow, Gerald B.Organometallic vapor phase epitaxial growth of AlGaInPAlx Ga,, In, _ x _ y P with x + y = 0.51, lattice matched to the GaAs substrate, has been grown by organometaUic vapor phase epitaxy. The simple, horizontal, IR heated system operates at atmospheric pressure using the reactants TMA1, TMGa, TMln, PH3, and K2. Alloys giving room temperature, band edge...Liquid phase epitaxial growth; LPE; Alloys; Surface morphology1985
12 Bhanu, Bir; Henderson, Thomas C.Range data processing: representation of surfaces by edgesRepresentation of surfaces by edges is an important and integral part of a robust 3-D model based recognition scheme. Edges in a range image describe the intrinsic characteristics about the shape of the objects. In this paper we present three approaches for detecting edges in 3-D range data. The ap...Range data; Edges; Recognition scheme; 3-D1985
13 Bhanu, BirRecognition of 2-D occluded objects and their manipulation by PUMA 560 robotA new method based on a cluster-structure paradigm is presented for the recognition of 2-D partially occluded objects. This method uses the line segments which comprise the boundary of an object in the recognition process. The length of each of these segments as well as the angle between successive ...PUMA 560 robot; Cluster-structure paradigm; 2-D partially occluded objects1985
14 Keller, Robert M.Rediflow architecture prospectusRediflow is intended as a multi-function (symbolic and numeric) multiprocessor, demonstrating techniques for achieving speedup for Lisp-coded problems through the use of advanced programming concepts, high-speed communication, and dynamic load-distribution, in a manner suitable for scaling to upward...Rediflow; Multi-function multiprocessors; Lisp-coded problems1985
15 Bhanu, BirSegmentation of complex outdoor scenesA new simpler approach to image segmentation via recursive region splitting and merging is presented. Unlike other techniques the kernel of splitting is based on a generalization of a two class gradient relaxation method and merging uses a statistical analysis of variance.Image segmentation; Outdoor scenes; Recursive region splitting; Segmentation algorithm1985
16 Henderson, Thomas C.The synthesis of visual recognition strategiesA coherent automated manufacturing system needs to include CAD/CAM, computer vision, and object manipulation. Currently, most systems which support CAD/CAM do not provide for vision or manipulation and similarly, vision and manipulation systems incorporate no explicit relation to CAD/ CAM models. CA...visual recognition; automated manufacturing systems; object manipulation1985
17 Panangaden, PrakashVerification of systolic arrays: a stream functional approachWe illustrate that the verification of systolic architectures can be carried out using techniques developed in the context of verification of programs. This is achieved by a decomposition of the original problem into separately proving the correctness of the data representation and of the individual...Verification; systolic arrays; stream function1985
