A surface light field is a function that assigns a color to each ray originating on a surface. Surface light fields are well suited to constructing virtual images of shiny objects under complex lighting conditions. This dissertation argues that surface light fields for 3D photography are a "...
Recovering 3D scenes from 2D images is an under-constrained task; optimal estimation depends upon knowledge of the underlying scene statistics. Here we introduce the Southampton-York Natural Scenes dataset (SYNS: https://syns.soton.ac.uk), which provides comprehensive scene statistics useful for un...
The force fields setting the fluid in motion originate directly in the fluid. Free convection occurs in the atmosphere, in oceans and near the surface of heated or cooled bodies, for example. For free convection, the Rayleigh, Grashof, Marangoni, Archimedes, Grigull and Schwarzschild numbers are...
Improved light receiving members which are characterized by having an special surface layer formed of a non-monocrystalline material containing tetrahedrally bonded boron nitride or a non-monocrystalline material containing said boron nitride and trihedrally bonded boron nitride in mingled state or by havin...
correspondences. Silva et al. [26] proposed to use an enhanced genetic algorithm to solve the range image registration problem using a robust surface interpenetration measure. Boughorbel et al. [27] defined an energy minimization function based on Gaussian fields to solve the 3-D automatic ...

(2D) flow fields have reduced much conjecturing around wall-bounded turbulent flow and have provided more detailed structural pictures38. Although the technique has been used to study flow features in premixed laminar flames39, the effect of puffing in pool fires40, to obtain air-entrainment rates...
Overall, we’re pretty chuffed withthis purchase. It’s a solid piece of kit that makes our desk look cool and keeps our mouse on point. It’s not perfect, especially if you’re after a charging powerhouse, but as a mouse pad that doubles as a light show and a charging spot, it’...
A method for matching a color of a target surface involves capturing a digital image of the target surface and a test card having a pattern of color fields, each color field having a known true color. The digital image is analyzed to determine the captured target color and the captured colo...
Structured light may be projected onto the surface, such that the position of structured light in the captured image allows determination of scale. A non-planar surface may be unwrapped. The surface may alternatively be projected into a plane to correct for the scene being tilted with respect ...
