It is very important part of pre-processing for get better results by image processing that get emphasized image by processing of source image. Emphasized image is not only good looking image but clear and sharp image. Emphasized images are used very useful data at contour extraction and image recognition in image processing. It have different image recognition by how much represent a origin scene in row quality image. Present algorithms that get emphasized premier image do not get clear picture of degree that want in various kind of images and there is shortcoming that need much process times being proportional size of picture quality or accumulation degree of histogram. In this paper, we propose method to change distribution chart that pixels occupy in histogram as subsequentness in reflex of various kinds as well as that picture quality reflex method to emphasize so that is suitable in practical use purpose originally of premier. Proposed algorithm re-allot histogram distribution by reverse tracking histogram. Experimental images are same result and take less processing time than histogram equalization.

This Study is purposed to comparative analysis in the case of balanced with Ethnic image fashion and the event of an unbalanced between fashion and make-up and to reconfigure on the make-up of the features on the Ethnic image Fashion in the 21st century. The result of this study is as follows. First, in the case of Japanese ethnic image make-up, to emphasize applied forms and formative characterization, they generally use circles and horizontal lines. Also the harmony between Japanese image make-up and primary colors like white and red strengthen ethnic images better. In the event of an unbalance between fashion and image make-up, fashion occurs dynamically in Africa and linearly in China. Sexy & natural image make-up also widely appear in the modern view. Second, in the case of African ethnic make-up balanced with African image fashion, the form is repeatedly dotted, widely water-colored, and mattedly textured using ash make-up colors such as white, red, gold, gray and so forth. African image make-up strongly expresses primitive natural beauty adding primal tribal painting art and mask forms. In case of an unbalance between fashion and image make-up, no distinctive ethnic image make-up appears. To emphasize natural patterns as well as splendid & decorative fashion, they try not to use primary colors, but instead focus on natural make-up and monotone colored point make-up, sexy make-up, avant-garde make-up, goth make-up, romantic make-up, glossy make-up.

Recently efficient image coding algorithms using zerotree have been proposed. In these methods, the locations of nonzero wavelet coefficients are encoded with a tree structure, called zerotree, which can exploit the self-similarity of the wavelet pyramid decomposition across different scales. These are very effective, especially in low bit rate image coding. In this paper, two zerotree image coding algorithms, EZW and SPIHT, are briefly introduced, and a new zerotree searching scheme is proposed to emphasize the significance of a wavelet coefficient by its orientations as well as its scale.

As technology in a computer hardware and software advances, efficient information retrieval from multimedia database gets highly demanded. Recently, it has been actively exploited to retrieve information based on the stored contents. However, most of the methods emphasize on the points which are far from human intuition or emotion. In order to overcome this shortcoming , this paper attempts to apply interactive genetic algorithm to content-based image retrieval. A preliminary result with subjective test shows the usefulness of this approach.

In this study, based on the postmodern feminism were investigated in the non-fashion areas of painting, advertising and fashion areas. And, fashion illustrations were analyzed visually in the aspect of the essentialism and deconstructivism that constitute the postmodern feminism. In addition, it was examined how women images were expressed in fashion illustrations that reflected the postmodern feministic ideas. The research results first, in fashion illustrations were the essen tialistic women images were grouped in the opening of women bodies and actively emphasize. the opening of women bodies were expressed bodies the fetishistic, ecstatic images, actively emphasize features were expressed the sexual, and realistic images. Secondly, and fashion illustrations the deconstructivistic women images were grouped androgynous features, genderous features, the distorted feminine gender features, complex features. androgynous features were expressed the powerful, grotesque, humorous, androgynous image, that genderous features of immature, boyish image, that the distorted feminine gender features of simple, ethnic, techno-cyber image, that complex features of complex images.

This paper proposes a method to improve the image quality by designing Unsharp Mask Filter (UMF) based on Retinex theory which controls the frequency pass characteristics adaptively. Conventional unsharp masking technique uses blurring image to emphasize sharpness of image. Unsharp Masking(UM) adjusts the original image and sigma to obtain a high frequency component to be emphasized by the difference between the blurred image and the high frequency component to the original image, thereby improving the contrast ratio of the image. In this paper, we design a Unsharp Mask Filter(UMF) that can process the contrast ratio improvement method of Unsharp Masking(UM) technique with one filtering. We adaptively process the contrast ratio improvement using Unsharp Mask Filter(UMF). We propose a method based on Retinex theory for adaptive processing. For adaptive filtering, we control the weights of Unsharp Mask Filter(UMF) based on the human visual system and output more effective results.

The unsharp mask technique emphasize the boundary of the image by adding the boundary of the original image. This technique improves quality by emphasize its boundaries but produce rough image from image noise. The multi channel unsharp mask is possible to enhance entire contrast of the image by applying at least two channels of unsharp mask. However, There is limitations to strengthen boundaries even if the scale strongly applies the multi channel unsharp mask technique. To solve this problem, linear scaling to nonlinear scaling by applying exponential function to existing multi channel unsharp mask technique. Experimental results show enhanced contrast for desired area because of control scaling in details compared with existing unsharp mask technique.

In this paper, we present a new synthetic high coding method which gives high image compression ratio. Given an image, only its low-pass component is transmitted by DCT coding` the high-pass component is not transmitted but synthesized using edge sharpening on the reconstructed low-pass image at the receiver. For the DCT coding which is used to encode the low-pass image, we used an improved version of Cox's variance estimator. Also, introduced are new image quality measures called GSNR and EPR which emphasize perceptual aspects of image quality. Experimental results show that the performance of the proposed synthetic high coding is better in various quality measures than that of Cox's adaptive transform coding. Also, it yields acceptable image quality with neither apparent block effect nor visible granular noise even at high compression ratio of about 30:1.
