In this study, a novel single-image based dehazing framework is proposed to remove haze artifacts from images through local atmospheric light estimation. We use a novel strategy based on a physical model where the extreme intensity of each RGB pixel is used to define an initial atmospheric veil (local atmospheric light veil). Across bilateral filter is applied to each veil to achieve both local...

The Joint Photographic Experts Group's image compression algorithm has been shown to be a very efficient and powerful method of compressing images. However, there is litde substantive information about which color space should be utilized when implementing the JPEG algorithm. Currendy, the JPEG algorithm is set up for use with any three component color space. The objective of this research was ...

The aim of this paper is to demonstrate how the new technologies introduced in recent 3D cards can be used in color image processing and analysis. We used the latest programmability feature available in 3D cards in order to implement and to test five color image processing algorithms: local mean filtering, RGB to L∗a∗b∗ and RGB to HSV color spaces conversions, local principal component analysis...

This paper proposes a new method for enhancing the contrast as well as brightness of color images, based on orthogonal D4 Wavelet transform human visual system and also considers distinction between the background and foreground of the images. The RGB (Red, Green, and Blue) values of each pixel in a color image are converted to HSI (Hue, Saturation, and Intensity) value. On the S components of ...

Accurate color rendering requires the consideration of many samples over the visible spectrum, and advanced rendering tools developed by the research community offer multispectral sampling towards this goal. However, for practical reasons including efficiency, white balance, and data demands, most commercial rendering packages still employ a naive RGB model in their lighting calculations. This ...

Content-based image retrieval has become hot topic for research. Only color, texture or shape feature extraction cannot give high precision. To get high precision, this paper proposes a new content-based image retrieval method that uses combination of color, texture and shape feature. The color moment will be calculated to extract the color feature, where the image will be converted from RGB to...

Color images have a wider range of applications than gray images. There are two ways to extend the traditional super-resolution reconstruction method color images: Super resolution reconstructs each channel image individually; Change RGB bands into YCrCb bands, then luminance component and interpolates chrominance components.These algorithms cannot effectively utilize property that edges textur...

A combination of digital image processing and field works provides a vision into differentiating between the rock units, in addition to contacts among them. Landsat 9 was used plot detailed geological map study area, located Al-Teeb city at Bajalia anticline, Missan Governorate, Southeast Iraq. The included geometric correction, enhancement, classification, use false-color composite technology ...
