Abstract (sommario):

La colorisation est le processus qui consiste à ajouter des couleurs aux images en niveaux de gris. C’est une tâche importante dans la communauté de l’édition d’images et de l’animation. Bien que des méthodes de colorisation automatique existent, elles produisent souvent des résultats insatisfaisants en raison de défauts tels que le débordement de couleur, l’incohérence, des couleurs non naturelles et la nature non trivial du problème. Par conséquent, une intervention manuelle est souvent nécessaire pour obtenir le résultat souhaité. En conséquence, il y a un intérêt croissant à automatiser le

Abstract (sommario):

A digital painter uses reference photography to add realism to a scene. This involves making n colors in a painting relate to each other more like n corresponding colors in a photograph, in terms of value and temperature. Doing this manually requires either experience or tedious experimentation. Color relationship transfer performs the task automatically, recoloring n regions of a painting so they relate in value and temperature more like n corresponding regions of a photograph. Relationship transfer also has applications in computational photography. In fact, it introduces a new paradigm for

Abstract (sommario):

Object appearance models are a consequence of illumination, viewing direction, camera intrinsics, and other conditions that are specific to a particular camera. As a result, a model acquired in one view is often inappropriate for use in other viewpoints. In this work we treat this appearance model distortion between two non-overlapping cameras as one in which some unknown color transfer function warps a known appearance model from one view to another. We demonstrate how to recover this function in the case where the distortion function is approximated as general affine and object appearance is

The purpose of this thesis is to develop a working methodology to color a grey scale image. This thesis is based on approach of using a colored reference image. Coloring grey scale images has no exact solution till date and all available methods are based on approximation. This technique of using a color reference image for approximating color information in grey scale image is among most modern techniques.Method developed here in this paper is better than existing methods of approximation of color information addition in grey scale images in brightness, sharpness, color shade gradients and di

Abstract (sommario):

In the field of computer vision and more specifically multi-camera systems color correction is an important topic of discussion. The need for color-tone similarity among multiple images that are used to construct a single scene is self-evident. The strength and weaknesses of color- correction methods can be assessed by using metrics to measure structural and color-tone similarity and timing the methods. Color transfer has a better structural similarity than histogram-based prefiltering and a worse color-tone similarity. The color transfer method is faster than the histogram-based prefiltering.

In particular, discoloured water, upon chlorination, is believed to produce carcinogens.

Microarray analysis was used to detect COX independent effects of sulindac on gene expression in human colorectal cells.

Abstract (sommario):

博士<br>國立中興大學<br>資訊科學研究所<br>93<br>A color transfer algorithm changes colors of the source image by referring to the color of the target image. Previous color transfer algorithms suffered from intensive and laborious works to select an appropriate source image to make the resultant image with plausible visual appearance. This paper presents two color transfer algorithms to make color transfer more efficient and versatile. The first algorithm we present is an efficient color transfer algorithm. In this algorithm, we propose a fuzzy classification technique to achieve the efficiency in color trans

碩士<br>國立交通大學<br>多媒體工程研究所<br>97<br>In this thesis, we propose a novel method for color transfer using histogram. We can construct the histograms individually for both source and reference images based on the statistical analysis of them. After the construction of histograms, we perform segmentation in order to separate the histograms into multiple sections. According to the relationship of corresponding sections between the source and target images, we do color transfer from target to source. At the same time, there will be parameter interpolation between pairs of sections to solve the artifact

Abstract (sommario):

碩士<br>國立中興大學<br>資訊科學與工程學系<br>106<br>Histogram shifting or difference expansion were two popular schemes used for reversible data hiding. Color transfer changes color in a source image by referring to color of the target image to produce a visually plausible resultant image. Color transfer provides an alternative approach to achieving the reversibility. In this thesis, we combine color transfer and message embedding to become a reversible data hiding algorithm. Specifically, we conceal a secret message generated by a secret key when producing the resultant image simultaneously. This approach fo

Abstract (sommario):

碩士<br>國立海洋大學<br>電機工程學系<br>91<br>Color images contain much homogenous regions information which can be divided into uniform regions by color characterization. There is no linear relationship among the color space transformations. In the previous, the color research, we found that most of researchers use gray level image segmentation methods to apply on color images. They totally ignore the color characterization. In recent years, some of them took the advantages of color to do segmentation in some device dependence color spaces. The goal of this research is to investigate an automatic image seg

Abstract (sommario):

碩士<br>逢甲大學<br>通訊工程所<br>98<br>Color-to-gray conversion in many applications requires preserving the visual appearance and feature discrimination of color images. The existing methods are still need of improvement in this aspect. We propose two color-to-gray conversion algorithms. One is the global mapping based and the other is the local-global mapping based. The proposed methods convert accurately various categories of color images to grayscale images, including natural images, computational images, and painting images. The global mapping scheme is simple and fast, yet it preserves feature dis
