76 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.

78 Weinstein, DavidThe analytic 3-D transform for the least-squared fit of three pairs of corresponding pointsWe derive the analytic transformation for minimizing the summed-squared-distance between three movable points in one three-space pose to three corresponding fixed points in another three-space pose. This change of basis is a general rigid-body transformation (translation and rotation), with the addi...3-D transform; summed-squared-distance; three movable points; Three-space1998

82 Hansen, Charles D.; Hollerbach, John M.Improved calibration Framework for electromagnetic tracking devicesElectromagnetic trackers have many favorable characteristics but are notorious for their sensitivity to magnetic field distortions resulting from metal and electronic equipment in the environment. We categorize existing tracker calibration methods and present an improved technique for reducing stati...Electromagnetic tracking; Tracking devices2001
83 Bhanu, BirShape matching of two-dimensional objectsIn this paper we present results in the areas of shape matching of nonoccluded and occluded two-dimensional objects. Shape matching is viewed as a "segment matching" problem. Unlike the previous work, the technique is based on a stochastic labeling procedure which explicitly maximizes a criterion ...Shape matching; Two-dimensional objects; Segment matching1984
84 Henderson, Thomas C.Pattern recognition in a multi-sensor environmentCurrent pattern recognition systems tend to operate on a single sensor, e.g., a camera. however. the need is now evident for pattern recognition systems which can operate in multi-sensor environments. For example, a robotics workstation may use range finders. cameras, tactile pads, etc. The Multi-se...Pattern recognition; Multi-sensor; Multi-sensor Kernel System; MKS1983
85 Henderson, Thomas C.From motes to Java stamps: smart sensor network testbedsWe have proposed Smart Sensor Networks (S-Nets) as an architecture and set of distributed algorithms to extract, interpret and exploit networked sensor devices. Heretofore, the development of this approach has been done in simulation. In this paper, we describe two complementary implementations o...Smart Sensor Networks; S-Nets2003-03-03
86 Henderson, Thomas C.Multisensor methods to estimate thermal diffusivitySeveral methods for the estimation of thermal diffusivity are studied in this work. In many application scenarios, the thermal diffusivity is unknown and must be estimated in order to perform other estimation functions (e.g., tracking of the physical phenomenon, or solving other inverse problems lik...2012-01-01
87 Henderson, Thomas C.An approach to three-dimensional scene databasesCurrent image database research is concerned for the most part with the encoding and processing of two-dimensional images. However, the most successful approach to computer vision is based on 3-dimensional information, organized as either stacks of 2-D images (e.g., the intrinsic images of Barrow an...Image databases; Three-dimensional; Scene databases1987
88 Harrison, Reid R.Design and implementation of multipattern generators in analog VLSIIn recent years, computational biologists have shown through simulation that small neural networks with fixed connectivity are capable of producing multiple output rhythms in response to transient inputs. It is believed that such networks may play a key role in certain biological behaviors such as d...2006-07

91 Henderson, Thomas C.Sensing strategies based on manufacturing knowledgeWe propose an approach for the inspection of machined parts that is based on knowledge of the actual manufacturing process for the parts to be inspected. A principal benefit of this approach is that sensing can be focused on those areas of parts where violations of tolerance specifications are most ...Machined parts; Inspection; Sensing strategies; Toolpaths1994
92 Thompson, William B.Geometric reasoning for map-based localizationAn essential aspect of map-based navigation is the determination of an agent's current location based on sensed data from the environment. Formally, this amounts to specifying the current viewpoint in some world model coordinate system. This localization process has two distinct components: one invo...Map-based localization; Map-based navigation; Geometric reasoning1996

95 Kessler, Robert R.Visual threads: the benefits of multithreading in visual programming languagesAfter working with the CWave visual programming language, we discovered that many of our target domains required the ability to define parallel computations within a program. CWave has a strongly hierarchical model of computation, so it seemed like adding the ability to take a part of the hierarchy ...Visual threads; multithreading; CWave1997
96 Henderson, Thomas C.Video based animal behavior analysisIt has become increasingly popular to study animal behaviors with the assistance of video recordings. The traditional way to do this is to first videotape the animal for a period of time, and then a human observer watches the video and records the behaviors of the animal manually. This is a time ...Hidden Markov Model; HMM; Animal Behavior Analysis2006-06-06
