Visual saliency detection has recently become a highly active topic in image processing, due to its wide range of applications. This paper proposes a novel saliency detection model based on discrete cosine transform (DCT). The dissimilarity between image patches is evaluated using DCT low-frequency coefficients and is inversely weighted by the spatial distance between patches. An additional weighting...
A novel, standardized geometric model of the human upper respiratory tract was created by aligning and processing the computed tomography (CT) scans of upper respiratory airway of healthy subjects. Digital three-dimensional (3-D) geometric model of 3 single human upper respiratory airway were generated from the CT scans and a methodology was developed to scale, orient, and align the models, after...
Being a relatively new class of host molecule, cucurbit[8]uril (CB[8], Scheme 1) has been studied extensively and used in many areas such as molecular machine, molecular switches and molecular wires etc[1–3]. While, acridine orange (AO)[4] is capable of cell-permeable, and interacts with DNA and RNA by intercalation or electrostatic attractions respectively, so it is widely used for cell staining,...
Rising demand with diminishing reserves of oil and gas spread the energy crisis all over the world. Renewable energy and efficiency technology are the keys to resolve the energy crisis. As the improvement in luminous efficacy, LEDs have been an energy-saving choice for general illumination and road lighting. This paper made a comparison between LEDs system and HPS system for road lighting to evaluate...
