Image hiding is a form of steganography that works by embedding data into a digital media for the purpose of identification, annotation, and copyrighting. This paper introduces a novel image steganography system, which embeds (RGB) secret image within (RGB) cover image chosen by an enhanced resilient back propagation neural network. The proposed system includes embedding and extraction phases. ...

Adv. Mater. 2009, 21, 1–5 2009 WILEY-VCH Verlag Gmb We demonstrate print-deposition of high resolution, patterned, multicolored thin films of luminescent colloidal quantum dot (QD)-polymer composites and use the printed patterns in fabricating robust, bright, full-color AC-driven displays. The benefits of AC electroluminescent (EL) displays include simple, low-cost fabrication and high reliabil...

A new method of contrast enhancement based on steerable pyramid transform is presented in this work. The use of steerable filters is motivated by the fact that the images are to be observed by human and therefore it would be better to incorporate some knowledge on the Human Visual System in the design of the image processing tool. Here, the frequency and directional selectivity of the HVS is mo...

Pod phenotypic traits are closely related to grain yield and quality. phenotype detection in soybean populations natural environments is important breeding, cultivation, field management. For an accurate pod description, a dynamic method proposed based on improved YOLO-v5 network. First, two varieties were taken as research objects. A self-developed three-dimensional color image acquisition veh...

Single sensor with Bayer pattern color filters are used to reduce size and cost of consumer digital cameras. These cameras use various demosaicing algorithms to construct the entire image with true colors from the acquired insufficient RGB (Red,Green and Blue) mosaics. In order to estimate original true colors, iterative demosaicing algorithms are being employed. These algorithms incur high cos...

This paper challenges the problem of estimating the original red–green–blue (RGB) image from a black-and-white (B&W) halftone image with homogeneously distributed dot patterns. To achieve this goal, training RGB images are converted into color-embedded gray images using the conventional reversible color to gray conversion method, and then converted into halftone images using error diffusion in ...

In this paper, we propose a green (G)-channel restoration for a red-white-blue (RWB) color filter array (CFA) image sensor using the dual sampling technique. By using white (W) pixels instead of G pixels, the RWB CFA provides high-sensitivity imaging and an improved signal-to-noise ratio compared to the Bayer CFA. However, owing to this high sensitivity, the W pixel values become rapidly over-s...

The purpose of this presentation is to stress the need for colour management whenever a computer is used for the acquisition, visualisation, or reproduction of coloured objects. By calibrating colour peripherals to a common standard, Colour Management System (CMS) software makes it easier to match the colours that are scanned to those that appear on the monitor and printer, and also to match co...

In the spirit of the HSV color space, we introduce a simple transform of the RGB color cube into a light/dark dimension and a 2D hue. The hue is a normalized (barycentric) triangle with pure red, green, and blue at the vertices, often called the Maxwell Color Triangle. Each cross section of the space is the same barycentric triangle, and the light/dark dimension runs zero to one for each hue so...
