  • A Politician Appearance Acceptance Model (PAAM model) was formed and designed based on an analysis of how the electorate would accept a female politician. The PAAM model evaluated factors which influenced the voter's view of the female politician based on appearance. Causative factors were assessed that impacted acceptance based on appearance and analyzed whether voting was influenced by the appearance image; appearance image preferences for a female politician included the classic, dramatic, romantic and natural images. Through validations, the appearance image and competency had a causative factor that contributed to the acceptance of the politician image. The Classic Image demonstrated the strongest and most important image among the appearance images. As voters were more interested in the appearance image of a female politician, more emphasis and weight was on the appearance image during the voting selection process.

  • 본 연구는 성공적인 기업 브랜드 이미지의 구축을 위한 전략으로서 브랜드 인지도에 의한 제품가치의 향상의 필요성을 확인하고 그 실행 방법으로서 크게 브랜드 이미지 분석과 이를 바탕으로 하는 제품 이미지 프로그래밍, 그리고 제품 이미지의 정합성 평가와 관리의 세 단계로 구성되는 제품 이미지 집중 체계 (PICS : Product Image Concentration System)를 제안하여 기업의 경쟁력 강화와 브랜드 관리를 위한 지침으로 활용하도록 하는 데 그 목적이 있다. 먼저 브랜드 이미지 분석은 이미지 연상기법을 통하여 브랜드 이미지의 성향을 파악하는 방법으로서, 제시된 시각적 자료와의 관여방식을 분석하여 기업이미지와 브랜드 이미지의 인지 방향을 측정하고 분석한다. 다음으로 제품 이미지 프로그래밍은 이와 같은 브랜드 이미지에 대한 분석을 바탕으로 디자인철학(Design Philosophy)과 디자인 원칙(Design Principles)을 정립하고, 비쥬얼 포지션 프로그래밍(Visual Position Programming)을 통하여 제품이미지의 지향방향을 가시화 하는 과정이다. 마지막으로 제품이미지 정합성 평가는 디자인 철학과 디자인 원칙의 적용 여부 등을 평가하여 브랜드에 정합한 디자인을 개발할 수 있도록 평가의 기준점을 제시하기 위한 것이다. 이와 같은 제품 이미지 집중 체계 (PICS : Product Image Concentration System)는 기업의 경쟁력 강화와 브랜드 관리를 위한 실제적인 방법으로서 디자인 작업에 있어서 이미지의 주관성으로 인한 계획과 적용 그리고 관리의 문제를 보다 객관적으로 해결하는 지침으로 활용될 수 있을 것으로 기대되며, 향후 표현중심어에 따른 이미지 스펙트럼의 세분화와 이미지의 비교 분석, 또 여기에 나타난 시각적 질서를 규명하는 제품 이미지 해석 프로그램에 대한 연구가 지속되어야 할 것이다.

  • Medical image segmentation is the process by which an original image is partitioned into some homogeneous regions like bones, soft tissues, etc. This study demonstrates an automatic medical image segmentation technique based on independent component analysis. Independent component analysis is a generalization of principal component analysis which encodes the higher-order dependencies in the input in addition to the correlations. It extracts statistically independent components from input data. Use of automatic medical image segmentation technique using independent component analysis under the assumption that medical image consists of some statistically independent parts leads to a method that allows for more accurate segmentation of bones from CT data. The result of automatic segmentation using independent component analysis with square test data was evaluated using probability of error(PE) and ultimate measurement accuracy(UMA) value. It was also compared to a general segmentation method using threshold based on sensitivity(True Positive Rate), specificity(False Positive Rate) and mislabelling rate. The evaluation result was done statistical Paired-t test. Most of the results show that the automatic segmentation using independent component analysis has better result than general segmentation using threshold.

  • Thresholding is a popular image segmentation method that converts a gray-level image into a binary image. The selection of optimum threshold has remained a challenge over decades. Many image segmentation techniques are developed using information about image in other space rather than the image space itself. Most of the technique based on histogram analysis information-theoretic approaches. In this paper, the criterion function for finding optimal threshold is developed using an intensity-based classuncertainty (a histogram-based property of an image) and region-homogeneity (an image morphology-based property). The theory of the optimum thresholding method is based on postulates that objects manifest themselves with fuzzy boundaries in any digital image acquired by an imaging device. The performance of the proposed method is illustrated on experimental data obtained by W-band millimeter-wave radiometer image under different noise level.

  • The lack of objective decisive criteria and the absence of analyzing tools accrued from the experiments on various types developed from space design process makes it difficult to select and execute alternatives for them. As an attempt of coping with these problems, the aims of this study is to establish space analysis' models and to propose possibility of analyzing models by utilizing the technology of image process. It is now under study in the field of artificial intelligence based on the accomplishment of digital images. This study focused on establishment an analysis model based on accomplished digital images and image processing framework. It helps utilize various processing technologies that are currently in use of image processes, and problems of the study can be supplemented through further follow-up studies. Finally, analysis model can be constructed gradually huge design data in the analogue data to the digital image database and be proposed with index in design or evaluation step.

  • The pursuit of a healthier life has created life style changes through exercise; in addition, an athleisure look as well as a combination of everyday clothes and sportswear has rapidly spread through sharing based on image-based SNS. Fashion related images shown in an image-based SNS are considered important resources for grasping micro-needs with regard to the sensibility of consumers. Therefore, this study analyzes the design characteristics of an athleisure look shown in image-based SNS. In order to analyze the athleisure look, images of the entire garment were collected and classified to enable content analysis methods that analyzed the design characteristics of each type. As a result, types were classified as sporty-athleisure, modern-athleisure, high-end athleisure, retro-athleisure, and romantic-athleisure. Looking at the characteristics of the athleisure look, it was shown that the design characteristics of each type were well expressed through differences in the direction, material, and details by matching between the items used. This study can be used in design development processes by deriving the characteristics of athleisure looks through an analysis of fashion images that appear in image-based SNS.

  • Image stitching method is a technique for obtaining an high-resolution image by combining two or more images. In X-ray image for clinical diagnosis, the size of the imaging region taken by one shot is limited due to the field-of-view of the equipment. Therefore, in order to obtain a high-resolution image including large regions such as a whole body, the synthesis of multiple X-ray images is required. In this paper, we propose a rapid stitching method of digital X-ray images using template-based registration. The proposed algorithm use principal component analysis(PCA) and k-nearest neighborhood(k-NN) to determine the location of input images before performing a template-based matching. After detecting the overlapping position using template-based matching, we synthesize input images by alpha blending. To improve the computational efficiency, reduced images are used for PCA and k-NN analysis. Experimental results showed that our method was more accurate comparing with the previous method with the improvement of the registration speed. Our stitching method could be usefully applied into the stitching of 2D or 3D multiple images.
