The use of uplighters for localised lighting has been handicapped by the lack of a simple design procedure. Study of the illumination field shows that, for certain purposes, the 'first bounce' reflected light from an uplighter can be treated as emanating from an imaginary point source above the...
The invention is an illumination unit for point illumination of a medium where at least one light emitter is arranged to illuminate at least one illumination face via a first lens arrangement and a microshutter arrangement. The lens arrangement has at least one microlens arranged with respect to ...
When doing point based rendering, the indirect illumination of each group's center point is computed instead of each shading point. We use an error strategy to make the indirect illumination compute adaptively. This method is several times faster than the standard point based global illumination ...
Method and system for point source illumination and detection in digital film processingOne aspect of the invention is a system for digital film processing. A point light source, such as a laser, directs light onto film coated with a processing solution. Light from the film is measured to ...
method uses the motion cues of each point. This provides two key benefits: first, it detects moving, rather than movable, objects (Fig.1b); second, it detects any moving object, or any moving part of the object, regardless of its shape or class (Fig.1a). As a model-based method ...
The invention provides a device and method for in-vivo imaging, for example, using an in-vivo imaging device including an imager a lens and an illumination source, all positioned behind a single viewing window. The in-vivo imaging device... A Pascal,Zvika Gilad,Haim Bezdin - US 被引量:...
Method of and system for writing a bragg grating point by point by point in an optical fiber A system for writing a Bragg grating point-by-point in an optical waveguide includes an illumination system for producing a primary beam. It further includes a diffraction grating to receive the primar...
Therefore, by counting the distribution of vanishing point locations in the GSRD and the USVID, it can be found that non-uniform grid-level labeling is more suitable for addressing the narrow waterway vanishing point detection problem. 4. Our Method 4.1. Similarity Calculation Method Based on ...
However, the amount of excess carriers in a laser cavity far exceeds what is possible by illumination during growth and the electron quasi Fermi level in a laser reaches even higher than the conduction band minimum. We expect this topic to garner attention in the near future. 4.2.5 DX and ...
In this paper, we present an a Point-Based Global Illumination method for light transport on translucent materials with refractive boundaries. We start by placing volume light samples inside the translucent material and organizing them into a spatial hierarchy. At rendering, we gather light from ...
