In recent studies on tone reproduction with the objective of reproducing natural looking colors in digital images, an integrated multi-scale retinex (IMSR) has produced great naturalness in the resulting images. Most methods, including IMSR, work in RGB or quasi-RGB color spaces. As such, this produces hue distortion from the perspective of the human visual system. Accordingly, this paper proposes the hue preserved multi-scale Retinex (HPMSR) method to obtain a high contrast and naturalness. The proposed method enhanced the $L^*$ and saturation values in CIELAB color space. As a result, the visibility in dark shadows in the resulting images was improved.

Color planning system can be treated as a decision support system which includes both the recommendation of main color and harmonious colors. In this paper, we propose techniques that are useful to enhance the harmonious color recommendation with the main color selected by user. In order to reflect the knowledge about suggestion of harmonious colors, we use Ostwald color harmony theory, that is very systematical and easy to implement. Actually, Ostwald color space is similar to HMMD color model in MPEG-7. Due to the similarity between two color spaces, Ostwald color space can be represented as a virtual HMMD color space. Accordingly, we propose a technique to align the HMMD color space with Ostwald color space, thereby it is capable of enhancing a performance to search the harmonious colors according to Ostwald harmony theory. For recommendation of delicate and more exquisite harmonious colors in equal hue plane, we made the virtual color space continuous. The system can recommend various harmonious colors according to Ostwald color harmony. He(she) can select harmonious colors among the suggestions from the system.

The subjective experience would degrade the current artificial artistic aesthetic analysis. Since Qiong kiln ceramics have a long history and occupy a very important position in ceramic arts, we employed computer-aided technologies to quickly automatically accurately and quantitatively process a large number of Qiong kiln ceramic images and generate the detailed statistical data. Because the color features are simple and significant visual characteristics, the color features of Qiong kiln ceramics are analyzed for the quantitative aesthetics. The Qiong kiln ceramic images are segmented with GrabCut algorithm. Three moments (1st-order, 2nd-order, and 3rd-order) are calculated in two typical color spaces, namely RGB and HSV. The discrimination powers of the color features are analyzed according to various dynasties (Tang Dynasty, Five Dynasties, Song Dynasty) and various utensils (Pot, kettle, bowl), which are helpful to the selection of the discriminant color features among various dynasties and utensils. This paper is helpful to promoting the quantitative aesthetic research of Qiong kiln ceramics and is also conducive to the research on the aesthetics of other ceramics.

Due to non-linear characteristics of color spaces, color corrections using linear conversions for real image near color reappearance causes color distortions. In order to overcome this problem, the Bezier Curve, constructed with a set of arbitrary plane in the linear theory, has been used. However, the Bezier Curve increases in proportion to the number of data points, resulting in higher computational complexities. This paper attempts to use a Triplicated Piecewise Bezier Cubic-Curve (TPBC-Curve) of which the degree is cubic on the whole interval while keeping the characteristics of Bezier Curves. By Comparing the TPBC-Curve with Bezier Curve of 20 degree, the paper not only reduces the distortion during color correction but also lessens the relative increase of workload that is caused by the color correction in a small zone.

In this paper, the relationship between RGB, HSV, La^*b^* colors and sugar content was analyzed using linear regression on apples harvested in the same region. First, as a result of examining the correlation coefficient with sugar content according to each color level, it was found that the (+) region having a positive coefficient and a (-) region having a negative coefficient were separated according to the color level. Also, the correlation coefficient between color and sugar content, represented by the average value, was 0.342 in the La^*b^* color space, which was higher than the coefficient in the RGB and hsv space. That is, this means that the sugar content is related to the color in the La^*b^* space. Also, in the complex color composed of regions with high sugar content, it was found to be R²=0.3627, indicating that it is related to sugar content. In all nine color spaces, it was found to be R²=0.3668. In this case, it was found that the coefficients of v and b^* had an effect on the sugar content. Due to this, it was possible to confirm the validity of the empirical prediction that the higher the b^* representing yellow, the higher the sugar content.

This study aims to determine adolescents' emotional response and preferences for varying interior designs of learning spaces available at community facilities in apartment across Seoul. In particular, the subjects have been fragmented by gender and age for comparative analysis of emotional responses across different demographics of adolescents. A survey on the preferred designs of learning spaces in community facilities revealed that 'elegant,' 'cheerful,' and 'temperate' are the three main emotional words selected for image tool development. Emotional assessment verified the validity of these terms. Between the two genders, adolescent males preferred 'temperate' images more while adolescent females preferred 'cheerful.' In terms of the design of learning space, adolescent females deemed the interior atmosphere and area space to be the most important factors, while adolescent males pointed to the color of furniture and lighting to be the most important. Such results imply that there is a clear difference of emotional response between adolescent males and females. The results also imply that different atmospheres and design priorities must be considered when designing gender-specific spaces.

The purpose of this study is to present a design proposal of the senior housing in the city of Kimje and design guidelines for making outdoor spaces for Korean elderly. To do this, this study examined previous research papers and scholastic writings, related to elderly housing, and analyzed study cases of elderly housing. As a result, design guidelines of outdoor spaces for elderly were classified 5 types. Entrance area of housing complex is subdivided into the condition of location, the entrance of housing complex, an access road, and a direction mark. Building entrance area is subdivided into an access and waiting area, a canopy facility, and the pattern and color of boundary. In & outdoor neutral area is subdivided into a spatial standard, a patio, and a terrace. Parking lots is subdivided into a spatial standard and an entrance access. Outdoor living area is subdivided into a spatial and social standard, the usage of movable chairs, a garden, a pocket park, a lawn area, a sports area, an active and passive sports area, a promenade, a lookout area and so on. In these study cases, outdoor living area is commonly located into a community space, a nature friendly space, a health & sports space, and an outlook space and it plays positive role to the elderly. However, versatile outdoor spaces such as horticultural therapy garden is needed, which can be able to stimulate the physical senses of the elderly. This proposal is meant to create new outdoor spaces of a senior housing and to enhance the way of life of elderly.

The aim of this study is to provide practical guide for exterior design in apartment and to propose a device to improve the quality of residential environment by the color planning. Color is a language of context and used as a visual aid to recognize the objects and spaces in the world around us. In this sense, each color perception is unique to its own setting and not subject to any universal rules of thumbs, Therefore, when designing with color, each setting will demand its own specific set of rules. A balanced color scheme has to make the environment more pleasant for people to live in . Fro the exterior in housing the use of color has to be considered not just in its wider context of the architecture or surrounding but as an element of the life of the inhabitant. So it is considered on the type of people who will live in and visual condition of site. In this study , the objective model of systematic design process for environmental color planning is proposed on the basis of theroetical background and references investigated, By the existing thesis, resident's preference of the exterior color and foumular of composition in apartment was invastigated . In general theories, based on the theory Birren's color harmony for color coordination an design principles, a device of exterior color design in apartment was suggested by the course of reasonable design process. Color in environment plays many different roles. It integrates the architecture with the site. If color is use well, it can soften architecture that is too harsh, it can give a sense of identity to different part of site and improve a city's image. The environmental color is effective media to enhance the aesthetic value of architecture and environment.

The paper proposes a new method of segmentation-based feature extraction to improve performance in pedestrian upper-body detection. General pedestrian detectors that use local features are often plagued by false positives due to the locality. Color information of multi parts of the upper body is utilized in figure-ground segmentation scheme to extract an salient, "global" shape feature capable of reducing the false positives. The performance of the multi-part color segmentation-based feature is evaluated by changing color spaces and the parameters of color histogram. The experimental result from an upper-body dataset shows that the proposed feature is effective in reducing the false positives of local feature-based detectors.
