In a single-chip digital color camera, a color filter array (CFA) is used to obtain sampled spectral components (red, green and blue) in an interleaved fashion. A color demosaicing operation is then carried out to determine the missing spectral components at every location. One of the problems in color demosaicing is that many of the interpolated images are affected by colored artifacts near th...

Color and size are two important attributes for quality evaluation of most food and bioproducts. Many of the quality factors affecting oil palm and white powder starch are determined primarily by visual inspection. Such inspections determined market price and to a certain extent consumers' preferences. However, the inspection of oil palm and white powder starch is a very repetitive and tedious ...

—With the development of multimedia technologies, color image compression requires higher performance. To address this need and fit the human visual system (HVS), this paper adopts the improved luminance quantization table obtained by duality nonlinear programming and the uniform chrominance quantization table, which are applied to JPEG-like color image compression algorithm based on all phase...

Due to the improvement of image rendering processes, and the increasing importance of quantitative comparisons among synthetic color images, it is essential to define perceptually based metrics which enable to objectively assess the visual quality of digital simulations. In response to this need, this paper proposes a new methodology for the determination of an objective image quality metric, a...

Slow motion replay and spatial zooming are special effects used in digital video rendering. At present, most techniques to perform digital spatial zoom and slow motion are based on interpolation for both enlarging the size of the original pictures and generating additional intermediate frames. Mainly, interpolation is done either by linear or cubic spline functions or by motion estimation/compe...

The ability to accurately record the color of a painting within an American museum is explored. Limitations in imaging techniques and hardware are current barriers to high quality. Interestingly, simple colormanagement techniques provide large improvement. Perhaps the greatest advantage is a decrease in visual adjustment. A review is presented of the author’s experiences in trying to digitally ...

This paper work directly towards the improving the quality of the image for the digital cameras and other visual capturing products. In this Paper, the authors clearly defines the problems occurs in the CFA image. A different methodology for removing the noise is discuses in the paper for color correction and color balancing of the image. At the same time, the authors also proposed a new method...

Multiple biological processes can generate sexual selection on male visual signals such as color. For example, females may prefer colorful males because those males are more readily detected (perceptual bias), or because male color conveys information about male quality and associated direct or indirect benefits to females. For example, male threespine stickleback often exhibit red throat color...

A new approach for tuning the parameters of MultiScale Retinex (MSR) based color image enhancement algorithm using a popular optimization method, namely, Particle Swarm Optimization (PSO) is presented in this paper. The image enhancement using MSR scheme heavily depends on parameters such as Gaussian surround space constant, number of scales, gain and offset etc. Selection of these parameters, ...

In this paper, we propose a new view synthesis technique for coding of multi-view color and depth data in arbitrary camera arrangements. We treat each camera position as a 3-D point in world coordinates and build clusters of those vertices. Color and depth data within a cluster are gathered into one camera position using a hierarchical representation based on the concept of layered depth image ...
