CMYK vs. RGB Color images are printed on paper by separating their colors into four component parts: cyan, magenta, yellow, and black ( CMYK ). Each of the colors in an image is created by assigning a percentage from 0–100 to each of the aforementioned colors (for example, a red color could be created from 0% cyan, 100% yellow, 100% magenta, and 0% black). The color image is then printed on a m...
We propose a new definition of the total variation (TV) norm for vector-valued functions that can be applied to restore color and other vector-valued images. The new TV norm has the desirable properties of 1) not penalizing discontinuities (edges) in the image, 2) being rotationally invariant in the image space, and 3) reducing to the usual TV norm in the scalar case. Some numerical experiments...
In single-sensor digital imaging a color filter array, that is overlaid onto the image sensor, makes color images possible. Incident light rays become band-limited and each sensor element captures either red, green or blue light. Interpolating the missing two color components for each pixel location is known as demosaicing. This paper proposes to firstly derive an estimated luminance image by l...
AbstractThe RGB color model is an additive color model that yields a broad array of colors in which three primary colors red, green and blue are added together in various ways.RGB is device dependent color model used in input devices like color TV and video cameras, image scanners etc. and output devices like mobile phone displays, LCD etc. Bacteria Foraging Optimization is a nature-inspired op...
Object recognition is conducted using red, green, and blue (RGB) images in object studies. However, RGB low-light environments or where other objects occlude the target cause poor performance. In contrast, infrared (IR) provide acceptable performance these because they detect IR waves rather than visible illumination. this paper, we propose an inter- intra-weighted cross-fusion network (Infusio...
reducing the number of colors in an image while preserving its quality, is of importance in many applications such as image analysis and compression. it also decreases memory and transmission bandwidth requirements. moreover, classification of image colors is applicable in image segmentation and object detection and separation, as well as producing pseudo-color images. in this paper, the kohene...
In this paper, we propose a new method for color image-based authentication that combines multispectral photon-counting imaging (MPCI) and double random phase encoding (DRPE) schemes. The sparsely distributed information from MPCI and the stationary white noise signal from DRPE make intruder attacks difficult. In this authentication method, the original multispectral RGB color image is down-sam...
Description of colors of insects and plants in biological research is often subjective and imprecise. A quantitative, statistical, and standardized method for describing colors by software analysis of digital images would be useful to researchers if readily available. An Internet Web page with JavaScript and Java applet was made that loads a digital image and analyzes the red, green, and blue (...
Steganography is the art of hiding the fact that communication is taking place, by hiding information in other information. In this paper we have investigate two methods of RGB image steganography one is pixel indicator technique and other is triple-A algorithem.They uses the same principle of LSB, where the secret is hidden in the least significant bits of the pixels, with more randomization i...
Understanding and comparing images for the purposes of data analysis is currently a very computationally demanding task. A group at Australian National University (ANU) recently developed open-source code that can detect fundamental topological features of a grayscale image in a computationally feasible manner. This is made possible by the fact that computers store grayscale images as cubical c...
