We report the implementation of a color-capable on-chip lensless microscope system, termed color optofluidic microscope (color OFM), and demonstrate imaging of double stained Caenorhabditis elegans with lacZ gene expression at a light intensity about 10 mW/cm(2).

We describe a new color edge detection scheme and a related diffusion process based on hyperbolic coordinates in color space. We derive intensity, hue and saturation based edge detectors and show that the intensity and hue based diffusion processes are governed by the heat equation familiar from conventional scale space theory. A qualitatively new differential equation is derived for the satura...

Image Steganography is the process of embedding text in images such that its existence cannot be detected by Human Visual System (HVS) and is known only to sender and receiver. This paper presents a novel approach for image steganography using Hue-Saturation-Intensity (HSI) color space based on Least Significant Bit (LSB). The proposed method transforms the image from RGB color space to Hue-Sat...

We have done a detailed analysis of the properties of the HSV (Hue, Saturation and Intensity Value) color space. Our emphasis is on the visual perception of the color of an image pixel with the variation in hue, saturation and intensity values of the pixel. Using the results of this analysis, we determine relative importance of hue and intensity based on the saturation of a pixel. We apply this...

The purpose of this paper is to enhance the colored images using the enhancement developed steady state genetic algorithm, SSGA, with modified fitness function to get more accurate result and less noise. In this paper the Hue Saturation Intensity (HSV) color model will be used, after enhance the S, H and V components the transformation will be made to RGB color model. We have developed three mo...

We analyze Rossi X–ray Timing Explorer (RXTE) Proportional Counter Array (PCA) data of the transient low mass X–ray binary (LMXB) system 1A 1744–361. We explore the X–ray intensity and spectral evolution of the source, perform timing analysis, and find that 1A 1744–361 shows ‘atoll’ behavior during the outbursts. The color-color diagram indicates that this LMXB was observed in a low intensity s...

Common compression systems treat color image channels similarly. Nonlinear color models like Hue-Saturation Value/ Brightness/ Luminance/ Intensity (HSV/ HSB/ HSL/ HSI) have special features for each channel. In this paper a new hybrid compression system is proposed for encoding color images in HSI color model. The proposed encoding system deals with each channel with a suitable compression tec...

introduction: discoloration of resin composites is a common reason for replacement of these restorations. the aim of this study was to eva-luate the influence of different light curing de-vices on color stability of a microhybrid resin composite. materials and methods: 80 disc-shaped speci-mens (8 mm in diameter, 2-mm height) were fabricated from filtek z250 resin composite. specimens were divid...

In this paper, we present a new and effective image indexing technique that employs local uni-color and bi-color distributions and local directional distribution of intensity gradient. The image is divided into 4 by 4 non-overlapping blocks. Each block, based on its gradient magnitude, is classified as uniform or non-uniform. Using the average of each color component for the pixels of a uniform...

Integrative Co-occurrence matrices are introduced as novel features for color texture classi"cation. The extended Co-occurrence notation allows the comparison between integrative and parallel color texture concepts. The information pro"t of the new matrices is shown quantitatively using the Kolmogorov distance and by extensive classi"cation experiments on two datasets. Applying them to the RGB ...
