In this paper, we introduce a digital cross-polarization and fluorescent color imaging system for quantitative evaluation of skin lesions. We describe the characterization of the imaging systems and the quantitative image analysis methods to show the feasibility for quantitative evaluation of skin lesions. The polarization color image was used to compute erythema and melanin index image which are useful for quantitative evaluation of pigmentation and vascular skin lesions, respectively. The fluorescent color image was used to quantitatively evaluate "sebum" and "vitiligo". In quantitative evaluation of various skin lesions, we confirmed the clinical efficacy of the imaging systems for dermatological applications. Finally, we sure that the imaging systems can be utilized as important assistant tools for the evaluation of skin lesions by providing reproducible quantitative result for widely distributed skin lesions.

In commercial digital-cameras, color-filter filters light according to wavelength range of color filter array (CFA) and the filtered intensities contain color information of light. Then, output data of CFA is transformed to final rendered image through demosaicing process. In image processing of digital-camera, the quality of the final rendered image is affected by optical cross talk of CFA, kind of CFA pattern etc. Basically, pattern of CFA plays important role in image quality of final image rendered by digital-camera. Therefore, an evaluation system capable of quantitatively evaluating CFA is needed. This paper proposes a novel evaluation system using existing and proposed image metrics for evaluating CFAs of digital-camera. Proposed CFA evaluation system consist of color difference in CIELAB and S-CIELAB, Structure SImilarity (SSIM), MTF50, moire starting point (MSP), and subjective preference (SP). MSP and SP are newly designed for the proposed evaluation system. Proposed evaluation system is expressed in polar coordinates to analyze the characteristics of CFA objectively and intuitively. Through simulations, we confirmed that proposed CFA evaluation system can objectively assess performance of developed CFAs.

This study attempted to investigate the perspective of the skirts of male and female students by analyzing the differences in image evaluation according to the constituent elements (type, length, and wearing method) of men's skirt designs in modern fashion. The study included 109 male and female college students from Generation Z residing or whose life center was in Gwangju Metropolitan City, to evaluate 12 images depicting types of men's skirts. First, the constituent image evaluation factors according to the constituent design elements of men's skirts were analyzed. Second, the differences in each constituent image evaluation factor based on the constituent design elements of men's skirt designs were analyzed. Third, the gender-based differences in image evaluation by men and women concerning the constituent design elements of men's skirt designs were analyzed. The analysis included relatively more women than men. The results of the image recognition dimension included the following categories: "attractive image," "evaluable image," "gender image," and "personality image." In modern fashion, skirts are used to express the diverse personalities of men's fashion. Thus, they are used beyond the stereotype of women's clothing, toward expanding and diversifying the image of men's clothing through mixing and creating a dichotomous image of men and women. It can be used as a design that suggests a gender-fluid image.

The objectives of this study were to investigate the differences of image evaluation of baseball uniform by uniform design and perceiver's gender. and to examine how baseball uniform preferences vary according to perceiver's gender. Stimuli consisted of 12 color photographs of a male model wearing a baseball uniforms which were manipulated according to the color of shorts and pants. A semantic differential scale of 23 items were used to evaluate the image of the stimuli. Subjects were 288 males and females. Five dimensions derived to account for the image of baseball uniform. These were manly, ability, activity, preference, and visibility. Wearing of red shirts had a positive effect on the evaluation of ability, activity, and visibility. Dark blue shirts had a positive effect on the evaluation of preference. Grey uniforms had negative effects on the evaluation of ability, activity, and visibility. Men liked white uniforms and vertical stripes uniforms of black and white more than dud women. Women talked dark blue shirts more than did men.

물리적 평가(physical evaluation)가 영상품질의 객관화와 정량화를 위한 토대를 제공함에도 불구하고, 부정확하고 가변적인 특성을 지닌 주관적 평가(subjective evaluation)가 영상평가에 중요한 역할을 하게 된다. 본 연구에서는 디지털 방사선 영상의 물리적 평가와 주간적 평가의 단점을 상호 보완하고 객관적 정량화를 위한 새로운 방법을 제안하고자 한다. 임상에 사용되고 있는 4대의 디지털 방사선 영상 촬영장치로부터 동일한 임상조건에서 흉부 팬톰 영상을 획득하였다. 물리적 영상평가를 위하여 디지털 흉부 팬톰 내에서 3개의 영역(폐, 심장, 그리고 복부)에 존재하는 CNR (contrast-to-noise ratio)를 측정하였고 분할(segmentation)과 정합(registration)등 다양한 영상처리기술이 적용되었다. 주관적 평가는 5명의 관찰자에 의한 저 대조도 물체의 식별 정도를 점수화 하였다. 두 평가의 특성을 보완 및 결합하고자 퍼지적분 이론이 도입되었다. 4대의 시스템으로부터의 평가결과가 비교되었으며, 물리적 평가와 주관적 평가가 항상 비례하지 않음을 보였다. 물리적 평가에서는 높은 점수를 보였던 시스템이 주관적 평가에서는 상대적으로 낮은 평가를 보였다. 본 연구에서 제안한 퍼지적분에 의한 영상평가의 정량화는 물리적 평가와 주관적 평가를 모두 포함하는 총체적인 평가 방법이며, 다양한 영상품질 평가에 유용할 것이라 사료된다.

This study evaluates the relationship among the evaluation structure of morphological elements, the satisfaction on exterior elements, and the image evaluation for the campus landmarks by campus type. The investigation results are summarized as follows. 1) The university headquarter was nominated as the university landmark, and the main reason for the nomination was the building's historic and locational value. 2) Of the morphological elements of the campus landmark, 'proportion and balance' and 'harmony and order' were deemed important, while 'diversity' was deemed less important. 3) For the satisfaction on the facility's exterior elements, the evaluation structure was different for each university. However, the factor of 'location of the facility' was deemed the biggest factor for satisfaction for all universities, while the facility's 'color and material' were found to be the most dissatisfying factors. 4) The image evaluation on the facility was different for each university. Although there was a strong skeptical image about 'liveliness', there was a very positive image about 'elegance' and 'scale'. 5) On the relationship between the satisfaction on exterior elements and the image evaluation, there was a different evaluation structure for each university. 'Facility's color and exterior material' were the main elements which improved the overall image of the facility. Thus, the study results strongly suggest that an important task is to determine the maintenance direction through the emphasis on the relationship between exterior elements and image satisfaction for each university.

Although the recognition and emotion about space is subjective and individual, if standard is proposed through common factor, objective, quantified space image evaluation will be available. In addition, space image evaluation standard caused by recognitive-emotional factor can meet requests of space users and increase psychological satisfactions. The purpose of this study is to grasp the space image caused by recognitive-emotional factor in space with PAD model and analyze the evaluation of space image giving visual, recognitive and emotional effects. The analysis result revealed that 'joyfulness' and access-avoidance had a very similar distribution. The result means that space is evaluated with the degree of 'joyfulness' for space and it is led by approach-avoidance behavior. The recognition factor that forms and evaluates space image and decides approach-avoidance is expressed as adjective images such as 'fresh, joyful, light and static and its emotional factors are adjective images such as 'calm, allowable, joyful and quiet'.
