Saturation vs. Intensity Distributions of Quality Color Images
نویسنده
چکیده
No-reference image quality assessment is an image characterization task of sorts. We explore the chromatic characterization of color images and relate it to image quality. Poor image quality is usually related to a loss of contrast; contrast is measured along the color dimensions of luminance, saturation and hue (which is a circular variable). The distribution of saturation as a function of luminance, both at the local and at the global level, is an informative type of measurement. Likewise, location-distribution plots give interesting image characterization tools for each of the dimensions of hue, saturation and luminance.

Novel Compression System for Hue-Saturation and Intensity Color Space
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...

A luminance based multi scale retinex (LB_MSRCR) algorithm for the enhancement of darker images is proposed in this paper. The new technique consists only the addition of the convolution results of 3 different scales. In this way, the color noise in the shadow/dark areas can be suppressed and the convolutions with different scales can be calculated simultaneously to save CPU time. Color saturat...

متن کاملPerceptual Quality Improvement of Stereoscopic Images
In general, 3D scene depth is affected by intensity and saturation difference according to human factor. Utilizing this information, we propose a novel method to improve 3D perceived depth of stereoscopic images. By varying the RGB colors especially at adjacent areas of an edge pixel, the depth perception is expected to be enhanced. For this, two methods for intensity transformation and one for...
متن کاملUnderwater image quality enhancement through composition of dual-intensity images and Rayleigh-stretching
The quality of underwater image is poor due to the properties of water and its impurities. The properties of water cause attenuation of light travels through the water medium, resulting in low contrast, blur, inhomogeneous lighting, and color diminishing of the underwater images. This paper proposes a method of enhancing the quality of underwater image. The proposed method consists of two stage...
