  • Since digital images and videos are rapidly increasing in the internet with the spread of mobile computers and smartphones, research on image retrieval has gained tremendous momentum. Color, shape, and texture are major features used in image retrieval. Especially, color information has been widely used in image retrieval, because it is robust in translation, rotation, and a small change of camera view. This paper proposes a new method for histogram refinement based on local color difference. Firstly, the proposed method converts a RGB color image into a HSV color image. Secondly, it reduces the size of color space from 2563 to 32. It classifies pixels in the 32-color image into three groups according to the color difference between a central pixel and its neighbors in a 3x3 local region. Finally, it makes a color difference vector(CDV) representing three refined color histograms, then image retrieval is performed by the CDV matching. The experimental results using public image database show that the proposed method has higher retrieval accuracy than other conventional ones. They also show that the proposed method can be effectively applied to search low resolution images such as thumbnail images.

  • Microdisplays based on organic light-emitting diodes (OLEDs) have a small form factor, and this can be a great advantage when applied to augmented reality and virtual reality devices. In addition, a high-resolution microdisplay of 3000 ppi or more can be achieved when applying a white OLED structure and a color filter. However, low luminance is the weakness of an OLED-based microdisplay as compared with other microdisplay technologies. By applying a tandem structure consisting of two separate emission layers, the efficiency of the OLED device is increased, and higher luminance can be achieved. The efficiency and white spectrum of the OLED device are affected by the position of the emitting layer in the tandem structure and calculated via optical simulation. Each white OLED device with optimized efficiency is fabricated according to the position of the emitting layer, and red, green, and blue spectrum and efficiency are confirmed after passing through color filters. The optimized white OLED device with color filters reaches 97.8% of the National Television Standards Committee standard.

  • Aging brings color-weakness to the eye due to yellowed eye sight. The 87% of information required for human behavioral decisions are visually perceived. Therefore, the color-weakness will affect behavior in many ways. Most of previous research regarding color planning for the aged focuses on discovering their preferred colors and reflecting the colors on facility color planning. But such research failed to identify the confused range of color cognitions due to the color weakness of the aged. The purpose of this study is to propose a design guide for fee-charging residential facilities for the elderly, reflecting upon color perception characteristics. An experimental simulation on aged vision using the UV filter and Y-2 filter, YA-3 filter alternating for general eyesight, 70 year-old and late 80 year-old was conducted. The results of this study are as follow : color perception is changed by crystalline lens aging process and yellowed eye sight. The recognition arrangement of colors was preferred to contrast harmony rather than similarity harmony and the dominant color is a warm color rather than a cool color.

  • We present Subaru Near-Infrared (NIR) photometry for globular clusters (GCs) in the giant elliptical galaxy NGC 4649 (M60) belonging to the Virgo cluster. NIR data are obtained in Ks-band with the Subaru/MOIRCS, and matching HST/ACS optical data available in literature are used to explore the origin of GC color bimodality. A clear bimodal color distribution is observed in the optical color (g-z), in which the ratio between blue and red GCs is 4:6. By contrast, the more metallicity-sensitive optical-NIR colors (g-Ks, z-Ks) show a considerably weakened bimodality in their distributions. The color-color relation of the optical and NIR colors for the GC system shows a nonlinear feature, supporting that the optical color bimodality observed in NGC 4649 GC system is caused by nonlinear color-metallicity relations (CMRs).

  • The hair designers are fashion leaders who affect hair color of people. Therefore, the purpose of this study is to give some tips to satisfy customers through surveying hair designers most like color and the criteria of products choice. To have practical result, I use survey method. I took 120 hair designers who work for Park Jun beauty salon for the survey data. Among these data, I used 103 for the final data of analysis. The results are following, male hair designers like natural brown and blue coral color for hair coating. In addition, they like black color for coloring. Female hair designers like much more various color, they like orange color for coating and natural brown for coloring. Hair designers much more satisfied for international brand goods in all criteria except price. All of hair designers have favorite goods for the quality and brand image. Therefore domestic brands need much more effort to improve quality and its brand image.
