This paper presents a high dynamic range (HDR) image zero watermarking method based on dual tree complex wavelet transform (DT-CWT) and quaternion. In order to be against tone mapping (TM), DT-CWT is used the three RGB color channels of HDR for obtaining low-pass sub-bands, respectively, since can extract contour change small after TM. The provides wide range, thus, three-color channel correlat...

Hung-Shing Chen Shih-Han Chen Abstract — Owing to the fast developments of computer networks and color imaging technologies, there is a tendency towards remote proofing in the printing or textile industries. More cases such as cross-display color matching will occur in the future information society. The problems of color mismatching we usually find in cross-display devices have been widely dis...

texture detection, texture analysis, texture synthesis, image analysis An algorithm is presented for the detection of textured areas in digital images. Texture detection has potential application to image enhancement, tone correction, defect detection, content classification and image segmentation. For example, texture detection may be combined with a color model and other descriptors to detect...

SynthesizedTextures represent continuous-tone images with a small set of vectors and color profiles. This representation is not only efficient in terms of compression ratio but also serve as the basis of photorealistic animations in AFX. Unlike standard synthetic texture techniques, the SynthesizedTexture imaging starts with analysis of photorealistic images or video sequences and conversion to...

A simple colorimetry-based printer calibration technique is described. The objective of this technique is to adjust the printed color to provide improved reproduction of CRT images that is good enough for most applications and easy to implement. It is based upon a one-dimensional look-up table for tone reproduction and a 3-by-3 matrix transformation for accurate hue reproduction of the additive...

Background: MicroRNA (miRNA) molecules have been detected in many body fluids and used as biomarkers. However, blood cell-derived miRNA molecules due to hemolysis have been shown to affect the amounts of plasma miRNAs. It is important to check the quality of plasma samples for clinical applications. In the present study, an objective method for quality checking plasma samples was investigated u...

When it comes to image coding, JPEG is the first thing that comes to mind. JPEG is the most widely used compression Standard for true color continuous-tone images. It was created by the Joint Photographic Experts Group (http://www.jpeg.org/) around 10 years ago, and although it delivers good quality at lowand medium-compression ratios, it lacks flexibility of use and its quality at high compres...
