Information security has recently become important in a number of application areas. Digital audio, video and pictures are increasingly furnished with distinguishing but imperceptible marks. Palette images are widely used in multimedia and Internet applications. In this project, a new method for data hiding in palette images with security protection by color ordering and mapping is suggested. F...

In this paper a new quantitative tissue characterization (QTC) program was developed for computing a standardized sets of parameters and quantitative color-mapping of these parameters for non-invasive accurate diagnosis of liver pathologies. In this program, histogram, co-occurrence matrix, runlength matrix, gradient texture feature coding, backscattering, attenuation and speckle parameters wer...

In recent years, various color difference formulas were developed for the CIELAB space, such as CMC, CIE94 and CIEDE2000. Although these formulas have achieved greater accuracy in perceptual measurement between colors, many applications cannot take advantage of this greater precision, because the Euclidean distances in CIELAB are not isometric in accordance with these new formulas. Thus, applic...

We present a new method to estimate color gamut from primary color spectra only. By using this method, the number of prints and measurements for printer characterization is greatly reduced, which is of particular importance if there are many ink candidates to be combined. The method consists in building a mapping between primary color spectra and their combinations, based on a training set. The...

An experimental system called SoundView has been developed, which allows the exploration of a color image through touch and hearing. The image is mapped onto a virtual surface with a fine-grained color dependent roughness texture. The user explores the image by moving a pointer device over the image. The pointer acts like a virtual gramophone needle, and the sound produced depends on the motion...

In video games, High Dynamic Range (HDR) rendering is commonly used and allows us to render more photo-realistic looking images. HDR rendering uses a tone-mapping process to achieve a Low Dynamic Range (LDR) rendering result for a display. The process compresses or clamps HDR color information to fit LDR devices which typically have an 8-bit color resolution. There are a lot of tone-mapping alg...

OBJECTIVE This study was undertaken to develop and test a 3-dimensional (3D) color thickness mapping technique on levator ani imaged with magnetic resonance imaging (MRI). METHODS Supine MRI datasets from 30 women were studied: 10 asymptomatic, 10 with urodynamic stress incontinence, and 10 with pelvic organ prolapse. Levators were manually outlined, and thickness mapping applied. Three-dimen...

Color inconsistency often exists between the images to be stitched and will reduce the visual quality of the stitching results. Color transfer plays an important role in image stitching. This kind of technique can produce corrected images which are color consistent. This paper presents a color transfer approach via histogram specification and global mapping. The proposed algorithm can make imag...
