In this paper, we propose a vision based hand motion recognition method for an untouchable user interface of smart devices. First, an original color image is converted into a gray scaled image and its spacial resolution is reduced, taking the small memory and low computational power of smart devices into consideration. For robust recognition of hand motions through separation of horizontal and vertical motions, the horizontal principal area (HPA) and the vertical principal area (VPA) are defined respectively. From the difference images of the consecutively obtained images, the center of gravity (CoG) of the significantly changed pixels caused by hand motions is obtained, and the direction of hand motion is detected by defining the least mean squared line for the CoG in time. For verifying the feasibility of the proposed method, the experiments are carried out with a vision system.

Kinect sensor version 2 is a kind of camera released by Microsoft as a computer vision and a natural user interface for game consoles like Xbox one. It allows acquiring color images, depth images, audio input and skeletal data with a high frame rate. In this paper, using depth image, we present a surveillance system of a certain area within Kinect's field of view. With computer vision library(Emgu CV), if an object is detected in the target area, it is tracked and kinect camera takes RGB image to send it in database server. Therefore, a mobile application on android platform was developed in order to notify the user that Kinect has sensed strange motion in the target region and display the RGB image of the scene. User gets the notification in real-time to react in the best way in the case of valuable things in monitored area or other cases related to a reserved zone.

The purpose of this study was to investigate the male perceiver's image evaluation on women's hairstyle and hair color, and to disclose the preference of the hairstyle and hair color. The experimental design was $2{\times}3{\times}3$ (hair $wave{\times}hair\;length{\times}hair$ color) factorial design by 3 independent variables. The stimuli were 18 women's upper body photographs which were output by computer simulation. The hairstyles were straight hair and wavy hair, and the types of the hair length were long, medium, and short hair. The hair colors were black, dark brown, and bright brown. Subjects were 154 men living in Seoul. The data were analyzed by using factor analysis, Cronbach's ${\alpha}$ reliability coefficient, three-way ANOVA, one-way ANOVA, and Duncan's multiple range test. The results of this study were as follows. Four image dimensions were derived by factor analysis. These were individuality, elegance, potency, and attractiveness. Male perceivers evaluated the women's long hairstyles to be more elegant than the short and the medium length hairs. The women's short hairstyles were perceived more potent than the long and the medium length hairs. The straight hairs were evaluated more elegant than the permed hairs, and the permed hairs were evaluated higher in individuality and attractiveness. The black hairs were perceived lowest in attractiveness, and the bright colors were perceived low in elegance. Male preferred the long brown straight hair first. They liked women's long hairs better than the short and the medium length hairs. Teenaged males preferred various hair colors more than those in their 20's and 30's did.

The purpose of this study was to investigate the effect of perceiver's social value, hair style, and hair color of object person on image perceptions. For social value variable, materialism and traditionalism were investigated. Subjects were 343 women in Seoul. Perceiver's materialism gave a significant influence on perception of elegance. The less materialistic group evaluated the hair style of object person more elegant than the more materialistic group. The more traditional group evaluated bright brown hairs less pretty than the less traditional group. This means that traditional people have less preferable image on bright brown hairs compared to the black and dark brown hair as it is different from Korean traditional hair color. Medium straight hair styles were evaluated lowest in preference and individuality. Short straight hairs were evaluated as the most elegant style and medium permanent hairs as the least elegant one. Long wavy hairs were evaluated highest in femininity, and straight hairs were evaluated lower in prettiness and activity than wavy hairs. The bright brown hairs were evaluated as the most individual color, and black was the least one. The bright brown was perceived lowest in elegance. Black and dark brown of the short straight hair style were perceived much more elegant than the bright brown of the same style, and black long wavy hairs were evaluated highest in femininity. The present findings provide that social value, hair style, and hair color are significant characteristics when perceiving women's image.

The purpose of this study was to find out the hair style image about variations of hair design elements. The method of this study was quasi-experimentation. The twelve color photographs of manikins with various hair style were used as the stimulus. As measuring instrument, a likert scale composed of 35 items of five point adjectives was used. The sample consisted of 157 males and 140 females residing in the Busan area. The range of the age is from 20 to 55. The survey was conducted from August to September in 2007. The data were analyzed by factor analysis, frequency, crosstabs one-way analysis of variance, Duncan's test and t-test used SPSS Packages. The results of this study were as follows: 1. As a result of factor analysis, 8 factors - romantic, natural, elegant, simple, classic, casual, modem and mannish were found out as constructing factors of hairstyle image. 2. As a result of hair style image analysis about variations of hair-length, The short hair style was perceived in modern, mannish, casual, sophisticate, medurm-length style in classic and elegant, long hair style was perceived to be high in romantic and natural. 3. As a result of hair style image analysis about variations of hair design elements, The length of hair style was the most influential element in hair design and secondly important one was the wave of hair style. The color of hair style didn't critical effect on image of hair style.

As on-line purchases is activated, customers' demand increases for the realistic and accurate digital information of a product design. In this paper, we propose a practical method that can generate a realistic 3D model of a real product using a 3D geometry obtained by a 3D scanner and its photographic images. In order to register images to the 3D geometry, the camera focal length, the CCD scanning aspect ratio and the transformation matrix between the camera coordinate and the 3D object coordinate must be determined. To perform this 2D-3D registration with consideration of computational complexity, a three-step method is applied, which consists of camera calibration, determination of a temporary optimum translation vector (TOTV) and nonlinear optimization for three rotational angles. A case study for a metallic coated industrial part, of which the colour appearance is hardly obtained by a 3D colour scanner has performed to demonstrate the effectiveness of the proposed method.

Black has been the most important color of all since the ancient times when the recognition of black roused, as well as during most of the eras; and can especially be said as the main color which controlled the chronicles of fashion. The purpose of the study was to broaden the application of black color image make-up by inquiring into make-up design elemental characteristics of lines and textures, after classifying magazine illustrations and advertisement make-up images using black. The photos which made effective use of black among fashion illustrations, magazine advertisements after 2001 were classified in to each type, and make-up expression method and characteristics according to design element of each image type was analyzed. The conclusion of such study was the following. 'Erotic image' showed contrast effect between eye make-up and lip color by using pale tone or red color. 'Mannish image' emphasized form and texture of eyebrow by restraining the colors of eyelids with natural brown tone eye make-up; 'Modern image' expressed vague eyebrow to bring the sensation of the direction of eye shadow on eyelids and eye line as well as slant line to relief. 'Kitsch image' showed free and light imagery by creating unique hair style with various colors; expressing lips mostly with colors similar to skin tone or by restraining colors on lips. 'Decadence image' showed messy and foul sensation with unstandardized eye make-up and matt skin of shimmer, glossy and pale tone, also with black colored lips; 'Retro image' expressed reinterpretation of images from 1920${\sim}$1960 to contemporary styles.

This paper proposes a six-color separation method of reducing unnecessary usage of colorants based on the limitation of total colorant amount and dot visibility ordering. First, the CIELAB values of input RGB image are estimated through the color-mixing model and compared with pre-calculated CIELAB values corresponding to all combination of CMYKlclm colorants with a constraint of color difference, thereby selecting initial CMYKlclm candidates. Next, the limitation on total colorant amount Is imposed on initial CMYKlclm candidates to remove the excessive amounts of colorants, and then final CMYKlclm candidates are determined by minimizing the usage of light cyan and light magenta in the dark region based on the dot visibility ordering of C, M, Y, K, lc, and lm. Through the experiment, the proposed method is shown to reduce the excessive amount of colorants with preserving good image quality.
