Pansharpening is the process to combine high-resolution panchromatic images with lower resolution multi-spectral images. The results have both properties of the input data, namely high-resolution and multi-spectral information. This method is used in novel digital aerial cameras and satellites. We compare pansharpened images captured by a digital aerial camera with full color film images acquir...
In children periodontal disease presents itself as symptoms of systemic disease, but very seldom does it develop, as in adults, into cases that accompany serious damage to the alveolar bone. Most common are the cases of localized filth and eruptive gingivitis. The majority of these cases of gingivitis are localized in the interdental papilla and marginal gingiva and very few of them affect the ...
A new technique for obtaining energy-variable multicolor cathodoluminescent display screensis presented. This technique employs radio frequency ion plasma sputtering of one thin-film phosphor material over a dissimilar phosphor substrate. The technique employed differs from the old "Penetron" screen inthat the substrate and the secondary phosphor layer are single-crystal materials. This results...
Background & Aims: Biocompatible packaging based on edible films containing active agents used in food to improve quality, extending product shelf life and reducing the risk of pathogen growth . The objective of this study was to prepare composite films from chitosan and starch containing 0, 0.5, 1 and 2% pomegranate pell extract (PPE) and to evaluate their antimicrobial, antioxidant and optica...
Electrophoretic deposition (EPD) is a conventional method for fabricating film materials from nanometer-sized building blocks, and exhibits the advantages of low-cost, high-efficiency, wide-range thickness adjustment, and uniform deposition. Inspired by the interest in the application of two-dimensional (2D) nanomaterials, the EPD technique has been recently extended to building blocks with 2D ...
We report a high-efficiency quantum dot (QD) film for high color gamut edge-lit LCD backlights. On the film's input surface, an array of asymmetric microprisms is used to preserve the large off-axis angle of the incident blue light. On the exit surface, the retroreflective microprisms retain blue light inside the film. The extended optical path effectively enhances the blue light's probability ...
A method to produce nanoscale films of AuAlx and PtAlx, and their mesoporous elemental derivatives is described, and the morphology and optical properties of these coatings explored. The color of the AuAlx film is bright purple, in agreement with ab initio calculations and experimental observations for the compound AuAl2, but becomes black after de-alloying with NaOH. The film of PtAlx is silve...
To enable high-level semantic indexing of video, we tackle the problem of automatically structuring motion pictures into meaningful story units, namely scenes. In our recent work, drawing guidance from Film Grammar, we proposed an algorithmic solution for extracting scenes in motion pictures based on a shot neighborhood color coherence measure. In this paper, we extend our work by presenting va...
A system has been developed that automatically extracts the iris region from photographs, computes the iris color in CIE u ́v ́ diagram color space, and corrects the color based on a standard calibration target. This system has advantages over previous manual methods in that it (1) is much less time-consuming because it is fully automatic, (2) corrects for the variability inherent in a film-based...
Students of the Rochester Institute of Technology’s School of Film and Animation produce hundreds of films each year. The focus of their studies is mainly on its story, direction, and editing. Managing what exactly happens to their scene from when they set up the lights on day one to the day the film screens in the Carlson Auditorium is the focus of this paper. There is often an assumption of ”...
