The extraction of lip region is essential to Lip Reading, which is a field of image processing to get some meaningful information by the analysis of lip movement from human face image. Many conventional methods to extract lip region are proposed. One is getting the position of lip by using geometric face structure. The other discriminates lip and skin regions by using color information only. The former is more complex than the latter, however it can analyze black and white image also. The latter is very simple compared to the former, however it is very difficult to discriminate lip and skin regions because of close similarity between these two regions. And also, the accuracy is relatively low compared to the former. Conventional analysis of color coordinate systems are mostly based on specific extraction scheme for lip regions rather than coordinate system itself. In this paper, the method for selection of effective color coordinate system and chromaticity transformation to discriminate these two lip and skin region are proposed.

Lip reading is a field of image processing to assist the process of sound recognition. In some environment, the capture of sound signal usually has significant noise and therefore, the recognition rate of sound signal decreases. Lip reading can be a good feature for the increase of recognition rates. Conventional lip extraction methods have been proposed widely. Maia et. al. proposed a method by the sum of Cr and Cb. However, there are two problems as follows: the point with maximum saturation is not always regarded as lips region and the inner part of lips such as oral cavity and teeth can be classified as lips. To solve these problems, this paper proposes a method which adopts the histogram-based classifier for the extraction of lips region. The proposed method consists of two stages, learning and test. The amount of computation is minimized because this method has no color conversion. The performance of proposed method gives 66.8% of detection rate compared to 28% of conventional ones.

This study consists of the stimuli of a female model in her twenties with twenty-three different facial make-up and survey on the differences of them for the development of make-up color system, based on the color-sense on the Korean's skin-tone and make-up color, to enforce the efficiency of beauty education. The result of this study and the suggestion is as followed. Firstly, Familiarity, Intelligence, Fitness, Charm, Tradition and Youth were came out as the result of factor analysis of make-up color image perception. Secondly, the stimulus of bare face was evaluated as more familiar and intelligent than the one with image make-up but perceived as unhealthy and not untraditional. Thirdly, skin tone had a big impact on both in lip color that's been applied in monotonous make-up and in image make-up that had been applied in contrastive make-up. Through these results, it is confirmed that the skin tone and make-up colors were influential variables in the research on facial image perception and preference against a female model in her 20s, and also the image test and preference can be changed according to the color contrasts. This research will be used as a basic tool for the development of make-up color applying system with image perception of statics of population variables and preference research. Also it aims to suggest the alternatives to perform the present collage make-up education for more systematic and organized education.

Popular music unites people who have different genders, ages, locals, and values. Through the popular music, youth interchange their emotion and create their fashion. Fashion and music formed the twin pillars on which the first historically significant youth sub-culture was built. Glam rock and Punk rock which won popularity in the 1970s influenced the fashion of the times. The purpose of this study is to compare Glam and Punk make-up which appeared as a symbol of the rebel against an older generation. The methodology utilized in this study was the analysis of materials from the survey through the literature, internet sites, and visual references. The results of this study are as follows: In face make-up, Glam used a white base to appear cosmic; on the other hand, Punk used a white base to appear pale and horrid. In eye make-up, Glam used black, pink, and blue eye shadow, and accented the eye by using black eye lines. Punk used black eye shadow, and drew black circles or squares around eyes. In lip make-up, Glam used pink, purple, red, and black lip color and silver and pink lip gloss to glitter. Punk used red and black lip color to appear horrid. In body make-up, Glam used glitter powder to appear with a bright skin. Punk drew tattoos and horror patterns in their body. The common themes of Glam and Punk make-up were rebellion, androgyny, and the beauty of ugliness as well as a self-created persona.

This study aims to investigate how the woman's beauty makeup trend had been changed in 1960s by analyzing the characteristics of woman's make-up in that period. For this study, a lot of documents and papers related to the woman's make-up were collected and reviewed. In particular, to analyze the characteristics of woman's make up trend in 1960s, a lot of women's pictures and makeup-related articles from 143 volumes of woman's magazines such as Yeowon and Jubusaenghwal were collected. Among the 624 pictures, fifty two pictures which were good enough for studying the total face and makeup were used for this study. The period of this study ranges from 1960 through 1969 and the analysis is focused on skin expression, eyebrow, eye shadow, eye line, lipstick, and brusher and through the related articles, the intention and contents of make up. were delivered and found out. The results are as follows. In early 1960s, the woman's make up was characterized by the make up ranging from unnatural and gray skin expression to dense pink skin expression, giving natural and glossy tint onto the skin and in particular putting a bright accent on the eyelid, eye or lip. In the mid-1960s, the make up style expressed skin more naturally, giving more shading on the eyelid, nose and lip, thus having cubic make-up. In the late 1960s, the make up became more refined and harmonized by using colors according to the TPO (time, place and objective) and skin color. The study results show that the women in 1960s pursued the "cute and young looking image" and used the make up to express their images young and cute. In the mid 1960s, the minimalism which pursued the pure and simple make up appeared in US. That trend affected the make up style of Korean women and hence Korean women showed more natural make up style in the mid and late 1960s.

본 논문에서는 입술 윤곽선을 검출하기 위한 다중 문턱치 기반의 검출방법을 제안하였다. 기존의 연구 중 Spyridonos 등이 제안한 방법은 입력영상을 RGB로부터 YIQ 좌표계로 변환하여 Q 성분만을 이용하여 Q 영상을 얻는다. Q 영상으로부터 변화 점 검출을 통하여 입술 모양의 좌우 끝점을 얻어낸다. 좌우 끝점에 대한 수직 좌표의 평균값을 이용하여 Q 영상을 상하로 분리하고, 상하 영역 각각에 대하여 별도로 Q값을 대상으로 문턱치를 적용하여 후보 윤곽선을 추출한다. 추출된 후보 윤곽선에 특징치 거리를 이용하여 최적의 문턱치를 찾고, 해당하는 윤곽선을 최종 입술 윤곽선으로 결정한다. 이 때 사용되는 특징치 거리 D는 후보 윤곽선 상의 점들을 기준으로 주변 영역에 대한 차이의 절대값을 이용하여 계산한다. 기존연구의 문제점은 세 가지인데, 첫째는 입술 끝점 추출 과정에서 피부영역의 과다한 참여로 입술 끝점의 추출의 정확도가 감소하고, 따라서 후속되는 상/하 영역 분리에도 영향을 미친다. 둘째는 YIQ 칼라 좌표계를 사용하였는데, 다양한 칼라 좌표계에 대한 분석이 미비하므로 추가적인 분석이 필요하다. 세 째, 최적 윤곽선의 선택 시 적용하는 거리 값 파라미터의 계산 과정에서, 문턱치를 적용하여 구한 해당 윤곽선 주변의 데이터들에 의한 변화분을 계산하여 변화가 가장 큰 윤곽선을 입술 후보로 채택하는데, 변화분의 최대치를 기준으로 하기 때문에 검출된 입술영역이 기준보다 축소되는 문제점이 있다. 첫 번째 문제점을 해결하기 위하여 피부영역의 계산과정 참여를 줄여서 성능을 30%정도 향상시켰다. 두 번째는 YIQ 외에 HSV, CIELUV, YCrCb 등의 칼라 좌표계에 대한 성능테스트를 거쳐 기존연구 방법이 칼라좌표계에 대한 의존성이 없음을 확인하였다. 세 번째는 윤곽선 주변의 변화분 검토 시, 윤곽선 포인트 당 변화분의 평균값 대신에 변화분의 총량을 적용하여 46% 성능개선 효과를 얻었다. 이상의 내용을 모두 적용하여 제안한 통합방법은 기존연구 대비 2배의 성능향상과 안정성을 확보할 수 있었다.

This study compares and analyzes bridal wedding styles in Korean and Chinese SNS. For this, 715 photos (362 in Korea and 353 in China) collected on social media (Instagram and Xiaohongshu) were used for analysis. The bridal wedding style was divided by item into wedding dress, makeup, and hairstyle, and detailed characteristics of images and designs were examined through content analysis and statistical analysis. First, in the case of Korea, many wedding dresses showed ball gowns and mermaid silhouettes, white colors, and no details and trimmings. As for the makeup, transparent and natural skin expression, straight eyebrows, and pink and peach lip colors were highlighted; and as for hairstyles, many long hair with half-covered ears appeared. Second, in China, a ball gown, mermaid silhouette, and white color are often seen in wedding dresses, and point colors and use of various details and trimmings are noted. The makeup showed a lot of bright skin expression, brown and black eyebrows, and red and brown lip colors. As for hairstyle, a lot of long hair with completely exposed ears appeared. Third, the comparison of bridal wedding styles between Korea and China indicated that China used relatively more details and trimmings in wedding dresses. As for makeup, Korea has a natural image, and China has a classic image. As for the hairstyle, there were many styles in which Koreans had half the ears covered, and Chinese had no bangs and completely exposed ears.

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.
