Computer graphics mean a reproduction of various information through image processing or the technology that is widely thought in makeup areas also, recently. Especially, Adobe Illustrator, unlike Adobe Photoshop used in image editing and correction, is software suitable for image drawing and reproducing beauty makeup. Beauty makeup is a work adorning human body to fit to the aesthetic standard in that period, and is a plastic art expressing shapes, colors and textures using design elements. Adobe Illustrator is a 2D graphics designing images using shapes having plane colors. In this study I studied techniques reproducing each element of contours and colors of beauty makeup through Adobe Illustrator CS. In other words, I have prepared a reference data by studying techniques reproducing beauty makeup using Adobe Illustrator CS. In this study, though, I couldn't try various things, because I limited facial contour and skin color to only one kind. Therefore, I hope, in the future, others can expand the ethnics of using Adobe Illustrator in more enriched ways by working on various facial contours and skin colors.

The purpose of this research is to suggest a scarf design which reflects the traditional culture native to Korea by making use of the combined pattern of jokgakbo patchwork and ddeoksal(rice cake). For research methodology, the computer design programs of Adobe Illustrator CS3 and Adobe Photoshop CS3 were used along with the related literature. For the combined sets of motif pattern, the following were consider: first, a combination of jogakbo in square shape and chrysanthemum in a rice cake mold; second, a combination of radius jogakbo and geometrical pattern; third, a combination of vertical and horizontal forms of jogakbo and rice cake pattern; fourth, a combination of yeouijumunbo and butterfly pattern in rice cake mold. For the scarf design with these applications, technical skills such as repeat, rotation, symmetry, free setup, and distortion were used for the combination motif. In terms of the shape of the design, there are two, square and lengthwise tetragons.

Luminance is the most important quantity in lighting design and illuminating engineering. There are three methods for measuring luminance; using a conventional luminance meter, through the illuminance measurement and subsequent calculations and using digital imaging photometer. Recently, HDRI(High Dynamic Range Imaging) technique introduces a new method of capturing luminance values in a lighting environment. The radiance maps from HDRI are commonly used as visual environment maps for lighting analysis applications. For the HDRI, HDR software is needed to create HDR image. Currently, there is number of HDR software available. The purpose of this paper is to investigate whether a luminance map can be accurately captured by the various types of HDR software which include HDR Shop and Photoshop. To accomplish this goal a set of experiments was conducted. In order to assess the luminance values of the HDR image from HDR software, the values had to be compared to the ones obtained with conventional methods of luminance measurement.

Digital forensics is the emerging research field for determining digital forgeries. Key issues of the tampered images are to solve the problems for detecting the interpolation factor and the tampered regions. This paper describes a method to detect the interpolation factors and the forged maps using the differential method and fast Fourier transform(FFT) along the horizontal, vertical, and diagonal direction, respectively from digital filtered tampered images. The detection map can be used to find out interpolated regions from the tempered image. Experimental results demonstrate the proposed algorithm proves effective on several filtering images by adobe $Photoshop^{TM}$ and show a ratio of detecting the interpolated regions and factors from digital filtered composite images.

The purpose of this study is to present the EV range in HDRI acquisition process to create luminance map. The proposed method in this study is to capture the scene at EV ${\pm}0$ that is the longest exposure points and reference point in the scene. With this reference point, sets of 25 LDRI test case were taken manually at ${\pm}2$ EV using the aperture-priority manual mode. The 25 HDRIs were created using Adobe Photoshop. The HDRIs were then imported Radiance lighting simulation program to be analyzed into falsecolor. The analysis results of the 25 HDRIs test case are 50[%] of the all tested case have a margin of error of 10[%]. In case of f/5.6, the luminance map generated with HDRI were similar to the spot luminance meter. As a result, the EV range to reduce error of luminance map generated with HDRI is EV $+2{\sim}{\pm}0{\sim}-10$.

본 논문은 시각적 워터마크의 삭제나 수정을 방지하기 위해 블록 기반 내용 인증(Block-wise content authentication) 방법을 제안한다. 제안한 방법은 원본 이미지와 워터마크 이미지를 사용하여 DCT 기반의 시각적 워터마크(Visible watermark)가 삽입된 이미지로 만든다. 다음, 블록 기반 서명(Block-wise signature)을 삽입하여 JPEG 과 같은 허용 가능한 이미지 조작에서는 정보가 유지되고, 워터마크의 삭제와 같은 악의적인 이미지 조작에는 인증을 허용하지 않는다. 또한 이미지의 조작된 부분을 알 수 있도록 로컬라이제이션(Localization)을 이용하여 조작된 부분의 위치를 파악한 수 있다. Lena를 포함한 여러 표준 영상을 사용하여 실험한 결과, 제안한 방법은 시각적 워터마크에 대한 다양한 공격에서 조작된 위치를 정확하게 표현할 수 있었다. 그리고 Photoshop 7.0의 Quality factor 11인 JPEG-90 압축에서 약 99%의 인증이 가능하였고, 블러링(Blurring)이나 샤프닝(Sharpening)과 같은 기타 공격에서는 각각 51%, 50%로 인증이 허용되지 않았다.

The purpose of this study is to evaluate the accuracy of luminance maps generated from five types of HDRI builder(High Dynamic Ranging Image builder) which include Photosphere, Bracket, Picturenaut, Luminance HDR and Photoshop. To accomplish this goal a set of experiments was conducted. In order to assess the luminance values of the HDR image from HDR image builder, the values had to be compared to the ones obtained from imaging photometer. After comparing measured luminance data using imaging photometer with those retrieved from the HDR images, Photosphere error rate estimated at 3% below.

Recently, Photo editing softwares such as digital cameras, Paintshop Pro, and Photoshop digital can create counterfeit images easily. Various techniques for detection of tamper images or forgery images have been proposed in the literature. A form of digital forgery is copy-move image forgery. Copy-move is one of the forgeries and is used wherever you need to cover a part of the image to add or remove information. Copy-move image forgery refers to copying a specific area of an image itself and pasting it into another area of the same image. The purpose of copy-move image forgery detection is to detect the same or very similar region image within the original image. In this paper, we proposed fast detection of forgery image using four step search based on discrete cosine transform and a four step search algorithm using discrete cosine transform (FSSDCT). The computational complexity of our algorithm reduced 34.23 % than conventional DCT three step search algorithm (DCTTSS).

This paper starts out with a review of the concepts of naturalism and natural clothes. Based on these concepts, the paper aims to create nature-friendly and high-value modem designs by grafting natural images from butterflies into human bodies. The images of butterflies are combined to show distinguished luxury and diversity with natural materials such as denim. As for the design technology, Adove Illustrator 10, Photoshop 7.0, and Prima Vision Textile Design System are used since they are very popular in the CAD system. The followings are the main findings of our research. Naturalism displays its objectivity based on its inherent interest in human nature and its factual description in scientific approaches with an intention to find a true meaning of human life in nature. Natural clothes can be defined as the clothes of natural silhouette which are made of pure materials in natural colors and dyes from natural motifs such as animals, plants or natural phenomena. We have realized that the visually distinguished looks of butterflies are indeed far more luxurious than those of any other insects and this visual distinction can be utilized to attract the attention from designers. Lastly, it turns out that the digital printing technique can create more variety in colors and design forms than the manual printing, thereby providing designers with more options and practicality.
