The female image has been changed incessantly with age and has been eminently represented in cosmetic advertisement. The female images are changed from the classical images to the active and professional images with the historical current of cyber, digital, and fusion. These changes in the expression of female image are largely due to the spread of post-modernism, feminism, de-construction (Kim, 1994), digital information revolution, and increase of income. The female images in cosmetic advertisement have been expressed very variously with fashion, marketing target, and characteristics of articles. (Im, 1997) The cosmetic advertisements of pure and graceful images were popular in the past. But nowadays individual image, womanly image, and unchanged beautiful image are in vogue. Individual image is very popular in young generation with very short fashion period. Active career woman image represents passion and beauty with extension of women' social roles. Unchanged beautiful image in modern industrial pollution stands for the desire of keeping the beauty in youth. Brand is very important factor to consumers in purchasing. Brand is no larger the simple concept in the past, and accepted as reflection of the image, social status, service, and life-style(Lee, 1998) consumers are very favorable to foreign cosmetics with the increase of overseas travels and import. This phenomenon is considered as very natural, especially in young generation. To create a successful brand image, the harmony of quality, psychological preference, advertisement, and reasonable price are required. According to the questionnaire research implemented by the subject of college women students in five universities in Seoul, the majority of college women students purchase domestic cosmetic brands in cosmetic specialty stores and depend on the tips of acquaintances. Quality, skin-trouble, and brand are considered as special regards for purchasing. Especially, internet shopping in purchasing marks high growth rate and preference for foreign cosmetics is very ardent. It can be expected that the 21st century is the epoch of various small production different from the mass-production in the 20th century. Female image will be probably expressed with individual, emotional, and professional image in the media of digital, fusion, cyber, and technology culture. It can be said that the tendency of cosmetic purchasing in the future will be more focused on brand image and life style.

Radar image data were collected through the on-line data acquisition system of A/D converter and personal computer, and the image was restorated on CRT or plotter after digital image processing of the data. The digital image processing system which was developed for this study, consisted of some kinds of software as follows : rearrangement, transformation, and enhancement of the image data in real space or frequency space by Fourier transform, edge detection of the image, compact processing, state inferential processing, and so on. Since the image of PPI radar sweeps from the center to the circumference of a circle, the image within a given period has the shape of fan. Therefore the acquired data were transformed to have the same interval as that of data in outmost concentricity. The results of various image processing methods using transformed data were better than those of the methods using original data.

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).

All kinds of artwork, including multimedia and digital image that has been subliminated into an af mediating two numbers 0 and 1 in recent age, are self-sufficient and autonomous in themselves. Nevertheless, each of those artworks can be realized as a real entity only if its appreciator is capable enough to explore some potential meaning out of it through his or her own perceptual work. According to Mikel Dufrenne, an artwork is composed of three existential tiers: "le sensible" or the sensible material; "fe representation" or the subject(le sujet), and "1′expression." Dufrenne contends that our esthetic perception can be realized by way of three steps that are comparable to those three tiers: perception of the presence of the body("le sensible"), contemplative perception by way of imagination("le representation"), and reflective perception ("1′expression") as a result of dialectics of sense and sensibility. This paper argues on the aesthetic perception with regard to digital image expressed by two numbers 0 and 1, putting focus on the epistemological role of sensibility(감) that explores "1′expression" a la Dufrenne.

A digital city model represents a 3D environment of a city with various city object information such as 3D building model, road, and land cover. Usually, at least two satellite images with some image overlap are necessary and a complex satellite-related computation needs to be carried out to create a city model. This is an expensive technique, because it requires many resources and excessive computational cost. The authors propose a methodology to create a digital city model including 3D building model and land cover information from a single high resolution satellite image. The approach consists of image pan-sharpening, shadow recovery, building occlusion restoration, building model extraction, and land cover classification. We create a digital city model using a single KOMPSAT-2 image and review the result.

Edge detection considers the important technical details of digital image processing. Many edge detection operators already perform edge detection in digital color imaging. In this study, the edge of many real color images that represent the type of digital image was detected using a new operator in the least square approximation method, which is a type of numerical method. The Linear Fitting algorithm is computationally more expensive compared to the Canny, LoG, Sobel, Prewitt, HIS, Fuzzy, Parametric, Synthetic and Vector methods, and Robert' operators. The results showed that the new method can detect an edge in a digital color image with high efficiency compared to standard methods used for edge detection. In addition, the suggested operator is very useful for detecting the edge in a digital color image.

Encryption of digital images has been requested various fields. In the meantime, many algorithms based on a text - based encryption algorithm have been proposed. In this paper, we propose a method of encryption in wavelet transform domain to utilize the characteristics of digital image. In particular, wavelet transform is used to reduce the association between the encrypted image and the original image. Wavelet packet transformations can be decomposed into more subband images than wavelet transform, and various position permutation, numerical transformation, and visual transformation are performed on the coefficients of this subband image. As a result, this paper proposes a method that satisfies the characteristics of high encryption strength than the conventional wavelet transform and reversibility. This method also satisfies the lossless symmetric key encryption and decryption algorithm. The performance of the proposed method is confirmed by visual and quantitative. Experimental results show that the visually encrypted image is seen as a completely different signal from the original image. We also confirmed that the proposed method shows lower values of cross correlation than conventional wavelet transform. And PSNR has a sufficiently high value in terms of decoding performance of the proposed method. In this paper, we also proposed that the degree of correlation of the encrypted image can be controlled by adjusting the number of wavelet transform steps according to the characteristics of the image.

Focus on Digital Fashion Image, the conceptual framework for the thesis is established from Virtuality in Digital Art. Formative characteristics and aesthetic characteristics were studied by classifying the Digital Fashion Image applied and expressed by digital media and technology. A detective research method was used for a case study. A literature study for case-by-case data was analyzed with focus on the works expressing fashion that utilized digital media and technology since the 2000s. Through this study, the Digital revolution has created the socio-cultural impact of a Virtual representation to implement technology and fashion culture that finds ways to take advantage of the image shown in a Digital Fashion Media by understanding Virtuality. The results are as follows. First, it was a re-formation of the fashion culture through the experience of virtuality with mental zone parameters between the media 'Mediation Code'. Reflect the reality of the virtual environment as represented by a cultural image of fashion brands and fashion that reset the team relationship and formed a Homo Ludens cultural code. Second, 'Interactive Exchange' acts on the exchange interaction between the method of digital technology, the human and the machine as well as the technical interoperability of network elements and techniques. This exchange is applied to fashion images that express emotion. Forming personalized fashion items and the user interactively storage that expresses the interactive exchange to forward the identity of the emotional fashion by a change in the message delivery system fashion. Third, the emphasis on intuitive artistic expression 'Synesthesia Immersion' induces a sense of immersion and excitement through the fusion of the interconnected. Enhance a visual image in fashion sensory representation and maximize a tactile and visual virtual reality involvement.
