Colorado 14ers, Pixel by Pixel
International Journal of Applied Geospatial Research, 2011This document describes a capstone learning exercise designed for undergraduates enrolled in an introductory geospatial tools course. The overarching theme of the exercise, Colorado 14ers, Pixel by Pixel, is mountain geography. While immersed in a digital mountainous landscape, students explore topics of geomorphology and geomorphometry and discover ...

We propose a novel grayness index for finding gray pixels and demonstrate its effectiveness and efficiency in illumination estimation. The grayness index, GI in short, is derived using the Dichromatic Reflection Model and is learning-free.

Pixels and 3-D Points Alignment Method for the Fusion of Camera and LiDAR Data
IEEE Transactions on Instrumentation and Measurement, 2019The fusion of light detection and ranging (LiDAR) and camera data is a promising approach to improve the environmental perception and recognition for intelligent vehicles because of the combination of depth and color information.

Essential Spectral Pixels for Multivariate Curve Resolution of Chemical Images.
Analytical Chemistry, 2019We propose a methodology to select essential spectral pixels (ESPs) of chemical images. These pixels are on the outer enve-lope of the principal component scores of the data and can be identified by convex-hull computation. As ESPs carry all the linearly-

Computational grid, subgrid, and pixels
International Journal for Numerical Methods in Fluids, 2019Free‐surface flows in rivers, estuaries, and coastal areas are strongly dominated by the geometrical details of the study area. Nowadays, accurate bathymetric data are easily available on raster‐based digital elevation models with an impressive spatial ...

Range From Focus Pixel-by -Pixel
Proceedings of the IEEE/RSJ International Conference on Intelligent Robots and Systems, 2005We describe a nd demonstrate an ambient lllumlnation method for range Imaging In parallel with and using the same sensor that is used for Intensity Imaging. Our method automates the well known "range-from-focus" method. It makes use of our reaiizatlon that range can be calculated directly from a focus error signal: It is not necessary to actually focus

ACM SIGGRAPH 2011 Talks, 2011
We present a new video mode for television sets that we refer to as display pixel caching (DPC). It fills empty borders with spatially and temporally consistent information while preserving the original video format. Unlike related video modes, such as stretching, zooming, and video retargeting, DPC does not scale or stretch individual frames. Instead,

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2001
Abstract Diamond based pixel detectors are a promising radiation-hard technology for use at the LHC. We present first results on a CMS diamond pixel sensor. With a threshold setting of 2000 electrons, an average pixel efficiency of 78% was obtained for normally incident minimum ionizing particles.
