본 논문은 안드로이드 스마트 폰 환경에서 정중앙 블록과 주변 블록들 간의 블록 대비도를 이용해 눈썹을 검출한 후, 눈썹과 눈 간의 기하학적 특성을 이용해 눈의 위치를 찾는 눈 검출 방법에 관한 것이다. 제안된 방법은 Haar-like 특징과 AdaBoost 알고리즘 그리고 적응형 템플릿 정합을 이용해 입력 영상에서 얼굴 영역을 검출한 후, 이를 이용해 좌측 및 우측 눈썹과 눈 탐색 영역을 산정한다. 눈썹 영역의 Integral Image에서 눈썹에 해당하는 부분이 주변 블록들에 비해 상대적으로 어둡다는 특성을 이용해 눈썹을 추출한다. 이와 동시에 각 눈 탐색 영역의 Integral Image에서 동공 블록이 나머지 주변 블록들에 비해 상대적으로 어둡고 대칭성이 양호하다는 특성을 이용해 눈 후보 영역들을 추출한 후 최대 블록 대비도를 갖는 블록의 중심화소를 동공 후보점으로 삼는다. 이후 눈의 위치는 항상 눈썹 하단에 위치하며 그 떨어진 정도가 사람마다 크게 다르지 않다는 기하학적 특성을 이용해 눈 후보 영역에서 나온 동공 후보 점들을 검증한다. 제안된 방법은 거리 및 조명 변화 그리고 안경 착용에 강인한 것이 장점이다. 눈썹을 먼저 찾은 후 기하학적 특성을 이용해 좌우 동공 후보점 쌍의 적합성을 검증함으로써 안경과 눈을 효과적으로 구분할 수 있고 눈이 감겨 동공이 가려진 상태에도 감긴 눈의 위치를 검출할 수 있다.

The objective of this study is to compare the modern transformation of a folk tale in each country. A folk tale is a story about a man who obtained an ability to see the original look of humans with tiger's eyebrows successfully found a new wife suitable for him by using them. In Korea, China, Japan, and India, folk tales similar to have been transmitted. 'Tiger's Eyebrows' is differently shown in each country like 'Wolf's Eyebrows' in Japan, 'Tiger's Whisker' in China, and 'Vulture's Feather' in India. This paper looked for works that modernly transformed this folk tale in each country. In the results, there were diverse works in each country such as fairy tale book, musical, short story, and game in Korea, full-length novel in China, and fairy tale, animation, and cartoon in Japan. Meanwhile, in India, there was only a mention of the folk tale in a collection of papers. Among them, there were works showing the significance of modern transformation in the aspect of genre or contents like a short story of Korea, a full-length novel of China, and a cartoon of Japan. The Korean novel shows that human is a being with the animal's instinct while human tries to ignore it. On the other hand, the Chinese novel shows that humans are not much different from animals especially in case when facing pains or death. The Japanese cartoon shows that it is meaningless to feel shame as human in the world which is filled with monsters or animals. In India, there were no works modernly transformed because Indian folk tales might be stories based on the mythic belief rather than fun.

The purpose of this study was to verify the efficacy of cosmetics containing peptides as a cosmetic method for eyelashes. The study subjects were 21 women aged 20 years, set as the experimental group (right eyelash) and the control group (left eyelash), and measured changes according to the use of peptide cosmetics for 4 weeks. As a result of the analysis, the change in the length and density of eyelashes showed significant differences in the interaction between the group and the experiment period, and in the main effect according to each experiment period (p<.001). In the change of eyelash density and thickness, it was found that there was a significant difference at week 3 and week 4 in the difference between groups by measurement period (p>.05, p>.01). Cosmetics containing peptides have been effectively proven to be an effective cosmetic method for safe and beautiful eyelashes by increasing the length and number of eyelashes to those who suffer from side effects caused by cosmetic procedures. In the future, we look forward to expanding research to a wide range of age groups.

In this paper, I proposed a eyebrow detection algorithm in human face, that is important element in facial recognition. The proposed algorithm consists of four processes: face region detection using color region segmentation. eye detection by template matching, eyebrow candidate region detection in detected eye region, and eyebrow detection by thresholding using the modified histogram that gets luminance value in the candidate region. The test results show that the proposed algorithm can detect eyebrow region very effectively in facial image.

If a salesperson is able to juage consumers' purchasing preferences by looking at their eyebrows shapes, he might be able to set up his sales strategies that will be helpful for the sales. In order to set up this kind of strategy, the difference of purchasing preferences in relation to the eyebrows shapes must be defined clearly. The purpose of this study is to analyze the difference of purchasing preferences according to eyebrows shapes. We group eyebrows shapes into five classes in physiognomy, and Analyze the difference of purchasing preferences according to eyebrows shapes. The result shows that compared with people with rising tails of eyebrows, people with declined ones prefer common, simple, gentle and noble clothing image.

This study attempted to develop and investigate the effects of hair-nourishing cosmetics containing saponin astragaloside from Astragalus membranaceus Bunge on eyebrow growth and development for eventual product development. For this, current use of hair nutrients was investigated in general consumers through a questionnaire survey. A test was conducted for 6 weeks against the same subjects divided into two groups: experimental group with 0.5% saponin astragaloside on the right eyebrow and control group without any astragaloside on the left eyebrow. The results were as follows. In the control group, no significant changes were found in terms of eyebrow length and thickness. In the experimental group with 0.5% saponin astragaloside added, eyebrow length, root, and thickness of the middle area considerably increased. In other words, saponin astragaloside was confirmed an effective natural substance. In addition, subjective assessments such as usability, marketability, and satisfaction assessments supported the usability and market value of saponin astragaloside. Such results reveal that hair-nourishing cosmetics containing saponin astragaloside from Astragalus membranaceus Bunge would be helpful in improving and maintaining eyebrow growth for those concerned about loss and shortening of their eyebrows, showing the potential of product development.

Iris recognition Is that identifies a user based on the unique iris muscle patterns which has the functionalities of dilating or contracting pupil region. Because it is reported that iris recognition is more accurate than other biometries such as face, fingerprint, vein and speaker recognition, iris recognition is widely used in the high security application domain. However, if unnecessary information such as eyelid and eyelash is included in iris region, the error for iris recognition is increased, consequently. In detail, if iris region is used to generate iris code including eyelash and eyelid, the iris codes are also changed and the error rate is increased. To overcome such problem, we propose the method of detecting eyelid by using pyramid searching parabolic deformable template. In addition, we detect the eyelash by using the eyelash mask. Experimental results show that EER(Equal Error Rate) for iris recognition using the proposed algorithm is lessened as much as $0.3\%$ compared to that not using it.

The iris recognition is a biometrics technology to extract and code an unique iris feature from human eye image. Also, it includes the technology to compare with other's various iris stored in the system. On the other hand, eyelashes in iris image are a external factor to affect to recognition rate of iris. If eyelashes are not removed exactly from iris area, there are two false recognitions that recognize eyelashes to iris features or iris features to eyelashes. Eventually, these false recognitions bring out a lot of loss in iris informations. In this paper, in order to solve that problems, we removed eyelashes by gabor filter that using for analysis of frequency feature and improve preservation rate of iris informations. By novel method to extract various features on iris area using angle, frequency, and gaussian parameter on gabor filter that is one of the filters for analysing frequency feature for an image, we could remove accurately eyelashes with various lengths and shapes. As the result, proposed method represents that improve about 4% than previous methods using GMM or histogram analysis in iris preservation rate.

With iris recognition algorithm, unique iris code can be generated and user can be identified by using iris pattern. However, if unnecessary information such as eyelash is included in iris region, the error for iris recognition is increased, consequently. In detail, if iris region is used to generate ins code not excluding eyelash and the position of eyelash is moved, the iris codes are also changed and the error rate is increased. To overcome such problem, we propose the method of detecting eyelash by using mask and excluding the detected eyelash region in case of generating iris code. Experimental results show that EER(Equal Error Rate) for iris recognition using the proposed algorithm is lessened as much as $0.18\%$ compared to that not using it.
