Segmentation and Classification of Human Forms Using LADAR Data

March 14, 2007
Author(s)
James S. Albus, Tsai Hong Hong, Tommy Chang
High resolution LADAR images of scenes containing human forms have been segmented and algorithms developed for recognizing human forms in various positions in both cluttered and uncluttered scenes. Registration of LADAR and color CCD images enhance the

Computation of Light Scattered Into Detector

January 1, 2000
Author(s)
Egon Marx
To compare the measured bidirectional reflectance distribution function (BRDF) of a rough surface to the results of a computation, we have to take into account the aperture of the detector and, more generally, the properties of the measuring instrument. We

UWB Signal Processing: Projection, B-Splines, and Modified Gegenbauer Bases

May 25, 2015
Author(s)
Howard S. Cohl, Stephen D. Casey
Ultra-wide band (UWB) systems require either rapidly changing or very high sampling rates. Conventional analog-to-digital devices have limited dynamic range. We investigate UWB signal processing via a basis projection method and a basis system designed for

Indoor ultrafine particles of outdoor origin: importance of building operating conditions

February 1, 2013
Author(s)
Dong H. Rim, Lance L. Wallace, Andrew K. Persily
… such as central air distribution fan operation and window position. Experiments were conducted involving … that the UFP infiltration varies with particle diameter, window position, and central fan operation. Infiltration … increases with particle size from 5 nm to 100 nm. Larger window openings lead to higher infiltration factors due to …

Sampling Architectures for Ultra-Wideband Signals

July 3, 2017
Author(s)
Howard S. Cohl, Steve Casey
Ultra-wideband (UWB) signal processing is a technology with many features that could develop into advances in communication and information technology. The technology has tremendous potential, but also presents challenges to the signal processing community
