In this work we propose a compression technique that makes use of linear and perceptually uniform CIE $La^*b^*$ color space in the JPEG image compression framework to improve its performance at lower bitrates. To generate quantization matrices suitable for the linear and perceptually uniform CIE $La^*b^*$ color space, a novel linear Contrast Sensitivity Function (CSF) is used. The compression performance in terms of Compression Ratio (CR) and Peak Signal to Noise Ratio (PSNR), is further improved by utilizing image dependent, variable and non-uniform image sub-blocks generated using a proposed histogram-based merging technique. Experimental results indicate that the proposed linear CSF based quantization technique yields, on an average, 8% increase in CR for the same reconstructed image quality in terms of PSNR as compared to the conventional YCbCr color space. The proposed scheme also outperforms JPEG in terms of CR by an average of 45.01% for the same reconstructed image quality.

This study investigates the effects of interior design elements on the satisfaction and preference for space. Field measurements and surveys were conducted in three coffeeshops where various interior design elements were applied. Results indicate that movable tables and chairs for two people were preferred in the space. They need to be placed flexibly according to the visitors' needs to improve satisfaction for convenience. To improve spatial satisfaction, the brightness of color applied to wall surfaces was recommended to be lower than that of color used for floor surfaces. The surfaces of space and interior design elements such as furniture also need to be kept clean. Lamps with lower color temperature were effective to enhance spatial satisfaction. Light sources should be shielded when a pendant lighting system with general diffuse type was used in space. Natural daylight through window was also required for better satisfaction level. Multiple linear regression implied that the cozy feeling by electric light, existence of daylight, flexible layouts for tables and chairs, color and quality of material for tables and floor were significant contributors to overall spatial satisfaction.

This study aimes to understand the principles in Theo Van Doesburg's architectural concept. Generally, Theo Van Doesburg has been thought that he betrayed De Stijl by acting contrary to the Neo-Plasticism which was constituted in early De Stijl by Mondrian and himself and by suggesting opposite one, Elementarism. Therefore this study tried to understand the principles that make his architectural concept, confirming the background of Elementarism. After studing relation, which Theo Van Doesburg has used, between space and color, it is concluded that he has unchanged principles of architectural concept from early De Stijl to last, opposite to general appreciation. So, Theo Van Doesburg acted to maintain equilibrium that exists for balancing the two elemental forces which contrast each other in relation between space and color. The equilibrium which he looked for aims to constitute harmonized dynamic space by dynamic rythem of equilibrium instead of Neo-Plastic effect. And using color, which used to be producing dynamic effect, he intended to maintain static effect for making dynamic rythem of equllibrium by the principles he made.

A robust and efficient text extraction is very important for an accuracy of Optical Character Recognition (OCR) systems. Natural scene images with degradations such as uneven illumination, perspective distortion, complex background and multi color text give many challenges to computer vision task, especially in text extraction. In this paper, we propose a method for extraction of the text in signboard images based on a combination of mean shift algorithm and weighting scheme of hue and saturation in HSI color space for clustering algorithm. The number of clusters is determined automatically by mean shift-based density estimation, in which local clusters are estimated by repeatedly searching for higher density points in feature vector space. Weighting scheme of hue and saturation is used for formulation a new distance measure in cylindrical coordinate for text extraction. The obtained experimental results through various natural scene images are presented to demonstrate the effectiveness of our approach.

The epidermal color is one of factors the space for ages. Instead of the epidermal color expression, it made with material and decoration under structure for make shade of meaning before have the new media. But now a days, the epidermal color of the fashion store is getting free owe to the development of color harmony, has a great notion that gets out of the subordinate from color, and it is a emphasized factor with expression and self-control. The epidermal color of the fashion store makes an effort to accept the development and changing of new media. It should show that there role and function is changing constantly according to a new technology, and it gave a motivation for reanalysis about existence and expression of the epidermal color. The purpose of this research is that look around the feature of the epidermal color system, elements, and principle. Then contemporary fashion store is expressive characteristics of epidermal color. Using epidermal color is not common, we can find lots of the case with surface color, layer color, interface color, though. The paper reflects on the meaning and concept of fashion store which enables the application of expressive characteristics on space through advanced technology. Meanwhile, the features of epidermal color such as immateriality of process and communication can be inferred from case analysis.

The demand for residential space is encompassing diverse ranges to keep pace with the times. Due to the Increase in wealth, people today want more functional and physical well being as well as giving more weight to the emotional aspect in spatial planning. This study paid special attention on the psychological effect of color--especially difference of warm/cold temperature--and the individual variation on favorable colors. 1. For a communal space (e.g. living rooms), subjects showed high preference of YR range of colors and warm colors. 2. For an individual space (e.g. bedrooms), subjects showed high preference of GY range of colors and neutral colors. 3. For a sanitary space (e.g. bathrooms), subjects showed high preference of PB and B ranges of colors, and cold colors. 4. For all of the above spaces, subjects showed high preference of warm colors.

A standard default color space, sRGB, provides compatibility for the transmission of color within the Internet color operating systems and device drivers. However, a display monitor we use generally have non-standard primaries and gamma characteristic different from those specified by sRGB. In this paper, correction methods of chromatic error for a non-standard display monitor are proposed. Experimental results show that the proposed method using the correction matrix reduced chromatic errors at in compared with the non-corrected image's on a non-standard display.

The purpose of this study is to grasp the preference of colors in housing spaces by different type of personality and color preference by classifying dwellers various characteristics by MBTI to obtain basic informations for the color plan that satisfies their inner desire. The results of this study are as followed. Firstly, we could say about the color distribution of living spaces like that. The ceiling and general wall showed that N(white) systems and YR of bright tone was mostly distributed. The color of floor showed that the calm tone of YR was mostly distributed. Secondly, as for the favored colors of finishing material at each space, the biggest distribution of preference color was found as N(white) group(series) in case of ceilings. As for general walls, bright tone of N(white) group showed most in living rooms. In case of that of the floor, it showed the largest distribution of calm tone of YR. Point wall was preferred bright and brilliant in various kinds of color. Thirdly, as in favor of colors of closing materials, sensible types(S) are concentrated on common color groups, on the other hand, intuition types(N) prefer color groups of various kinds not only general preferred colors.
