The increasing prominence of portable system and the need of limit power consumption in very high density VLSI chip have led to rapid and innovative development in low-power design during the recent years. A multiplexer, sometimes referred to as a "MUX", is a device that selects between a numbers of input signals. This paper represents the simulation of different 2:1 MUX configurations and thei...

<p style='text-indent:20px;'>Retinex theory is introduced to show how the human visual system perceives color and illumination effect such as Retinex illusions, medical image intensity inhomogeneity shadow etc.. Many researchers have studied this ill-posed problem based on framework of variation energy functional for decades. However, best our knowledge, existing models via sparsity nonco...

Decomposing an input image into its intrinsic shading and reflectance components is a long-standing ill-posed problem. We present a novel algorithm that requires no user strokes and works on a single image. Based on simple assumptions about its reflectance and luminance, we first find clusters of similar reflectance in the image, and build a linear system describing the connections and relation...

Underwater detection equipment with fish technology has broad application prospects in marine fishery resources exploration and conservation. In this paper, we establish a multi-scale retinex enhancement algorithm feature-based model to improve underwater accuracy ensure real-time performance. During image preprocessing, the combines bionic structure of retina classical theory filter out enviro...

The goal of realistic image rendition is to recover the acquired image under imperfect illuminant conditions, where non-uniform illumination may degrade image quality with high contrast and low SNR. In this paper, the assumption regarding illumination is modified and a variable exponent functional model for Retinex is proposed to remove non-uniform illumination and reduce halo artifacts. The th...

This work presents a local (spatially-variant) gamut reduction algorithm that operates only on the saturation channel of the image, keeping hue and value constant. Saturation is reduced by an iterative method that comes from inverting the sign in a 2D formulation of the Retinex algorithm of Land and McCann. This method outperforms the state-of-the-art both according to a quantitative metric and...

This paper investigates the lateral vibration of single-layered graphene sheets based on a new theory called doublet mechanics with a length scale parameter. After a brief reviewing of doublet mechanics fundamentals, a sixth order partial differential equation that governs the lateral vibration of single-layered graphene sheets is derived. Using doublet mechanics, the relation between natural f...

In this paper we extend the discussion in the background paper, to consider some potential applications of the Thurstone method of Paired Comparisons. Because the analysis is modeled at the level of individuals rather than of groups it is much more powerful than the old method. There are two parts to it which may be called The Model and The Misfit. The model part constructs a single scale showi...
