چکیده

The world of color image difference modeling can be considered relatively young, when compared with the rich history of general color difference equations. While young, this area of research is well beyond the primordial soup stage. In this paper we present a framework for describing the evolution of color image difference models. This framework builds upon the S-CIELAB model, which in turn was built upon the CIELAB model and the CIE color difference equations. The goal is to create a modular, extendable color image difference model.

Predicting Cut Rose Stages of Development and Leaf Color Variations by Means of Image Analysis Technique

The monitor and prediction of crop developmental stages, particularly harvest time, play an important role in planning greenhouse cropping programs and timetables by cut rose producers. There have been many scientific reports on the application of image analysis technology in estimating greenhouse crop growth stages. In the present research, we studied leaf color variations over time by taking ...

A New Method for Color Gamut Mapping by Genetic Algorithm

To reproduce an image, it is necessary to map out of gamut colors of the image to destination gamut. It is clear that the best color gamut mapping introduces the perceptually closest image to the original one. In this study, a new color gamut mapping is purposed by the aid of Genetic Algorithm (GA). The color difference between the original and mapped images based on S-LAB formula was chosen as...

On Contrast Sensitivity in an Image Difference Model

The importance of the human contrast sensitivity function (CSF) in a color image difference metric is examined. The contrast sensitivity function is used to extend traditional color difference equations for use with complex image stimulus. Three CSF models of various complexities are evaluated using psychophysical image difference data. Additionally, two models of spatial frequency adaptation a...

From Color Image Difference Models to Image Quality Metrics

Color difference research has recently culminated in the creation of the CIEDE2000 color difference equation. This equation has been shown to accurately predict perceived differences between simple stimuli on a solid background. A similar metric is desired to predict differences of complex stimuli, such as color images. Such a metric would be useful for predicting both threshold and supra-thres...

فشرده‌سازی تصویر با کمک حذف و کدگذاری هوشمندانه اطلاعات تصویر و بازسازی آن با استفاده از الگوریتم های ترمیم تصویر

Compression can be done by lossy or lossless methods. The lossy methods have been used more widely than the lossless compression. Although, many methods for image compression have been proposed yet, the methods using intelligent skipping proper to the visual models has not been considered in the literature. Image inpainting refers to the application of sophisticated algorithms to replace lost o...
