151 Hansen, Charles D.; Henderson, Thomas C.CAD-based 3-D object recognitionWe propose an approach to 3-D object recognition using CAD-based geometry models for freeform surfaces. Geometry is modeled with rational B-splines by defining surface patches and then combining these into a volumetric model of the object. Characteristic features are then extracted from this model ...Object recognition; Strategy trees; Geometric knowledge representation; Automatic feature selection1989
152 Hansen, Charles D.CAD-based computer vision: the automatic generation of recognition stragtegiesThree-dimensional model-based computer vision uses geometric models of objects and sensed data to recognize objects in a scene. Likewise, Computer Aided Design (CAD) systems are used to interactively generate three-dimensional models during these fields. Recently, the unification of CAD and vision s...1988
153 Hansen, Charles D.; Henderson, Thomas C.CAD-based roboticsWe describe an approach which facilitates and makes explicit the organization of the knowledge necessary to map robotic system requirements onto an appropriate assembly of algorithms, processors, sensor, and actuators. In order to achieve this mapping, several kinds of knowledge are needed. In this ...CAD-based robotics; CAD-based vision; CAGD System1987
154 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.

160 Carter, Tony M.Cascade: a hardware alternative to bignumsThe Cascade hardware architecture for high/variable precision arithmetic is described. It uses a radix-16 redundant signed-digit number representation and directly supports single or multiple precision addition, subtraction, multiplication, division, extraction of the square root and computation of ...Cascade hardware; Bignums; Precision arithmetic1989

162 Gopalakrishnan, GaneshCase studies in symbolic model checkingThe need to formally verify hardware and software systems before they are deployed the real world has been recognized for several decades now. This is especially true of concurrent systems that are even more difficult to debug than sequential systems. For example, many of the protocols that get emp...Symbolic model checking; Hardware verification; Software verification1994
163 Riloff, Ellen M.Case study in using linguistic phrases for text categorization on the WWWMost learning algorithms that arc applied to text categorization problems rely on a bag-of-words document representation, i.e., each word occurring in the document is considered as a separate feature. In this paper, we investigate the use of linguistic phrases as input features for text categoriz...Learning algorithms; Text categorization; Linguistic phrases; Information extraction patterns; AutoSlog-TS1998
164 Hansen, Charles D.Case study of isosurface extraction algorithm performanceIsosurface extraction is an important and useful visualization method. Over the past ten years, the field has seen numerous isosurface techniques published, leaving the user in a quandary about which one should be used. Some papers have published complexity analysis of the techniques, yet empirical...Isosurfaces; Contours2000
165 Cates, Joshua E.; Whitaker, Ross T.; Jones, Greg M.Case study: an evaluation of user-assisted hierarchical watershed segmentationWhile level sets have demonstrated a great potential for 3D medical image segmentation, their usefulness has been limited by two problems. First, 3D level sets are relatively slow to compute. Second, their formulation usually entails several free parameters which can be very difficult to correctl...Watershed segmentation; Brain tumor imaging2004-02-27

167 Regehr, JohnCause reduction for quick testingAbstract-In random testing, it is often desirable to produce a "quick test" - an extremely inexpensive test suite that can serve as a frequently applied regression and allow the benefits of random testing to be obtained even in very slow or oversubscribed test environments.
