The purpose of this study is to know on the changes characteristics of eye brow forms of the wester women. A facial image which people recognize contents on changes of image according to various eye brow changes on the face. Various changes of image were seen by length, angle and thickness of eye brow types. The ancient Egyptians used antimony powder to blacken their brows huge black lines. In medieval times, women shaved both their eye brows and their hairlines to give a pure look. The early nineteenth century, brows were untweezed and natural. In the 1920s, when women started paying attention to their faces and their freedom, brows were tweezed, narrowed. In the 1930s, the idealized faces of Jean Harlow, Marlene Dietrich and Greta Garbo - narrow tracery of drawn on brows. The eyebrows is filled various shape of the 1950s. In the 1970s, the Disco Decade of Dreadful tastes, women were at their tweezers again, manicuring their brows. Brooke Shields's natural-looking brow would be an example of the 1980s. In the 1990s, the eyebrow designed by superstar makeup artists who determined the look of fashion model and screen star.

This study is designed to find women's makeup color preferences according to their pursuing clothing image and clothing behavior. Subjects were 515 women. from 18 years to 40 years old, who are interested in color makeup and use various products. The SPSS statistical program was used for analyzing the demonstrative results of questionnaire survey. The results of this study are as follows : 1. According to color makeup preference by the pursuing image in clothing. those groups who want to have conservative and neat image and who prefer feminine and intellectual image showed the preference of brown lipsticks and eye-shadows, while groups who want to have vivid image preferred orange lipsticks and pink eye-shadows. 2. In the case of casuals, all groups preferred pink eye-shadows and lipsticks. While those groups who want to have intellectual image preferred brown lines after pint groups who want to have sexy and vivid image preferred orange and red lipsticks and blue and green eye- shadows. 3. In preference comparison of color makeup by clothing behavior, those groups who attach practicality, symbol for social status. and social acknowledgment preferred red and brown lipsticks, and brown eye-shadows. 4. In the case of wearing casuals, all groups liked pink eye-shadows and lipsticks the best. whereas the group who want to have social acknowledgment Preferred beige lipsticks and brown eye-shadows.

Eye movements serve vision by placing the image of an object on the fovea of each retina, and by preventing slippage of images on the retina. The brain employs two modes of ocular motor control, fast eye movements (saccades) and smooth eye movements. Saccades bring the fovea to a target, and smooth eye movements prevent retinal image slip. Smooth eye movements comprise smooth pursuit, the optokinetic reflex, the vestibulo-ocular reflex (VOR), vergence, and fixation. Saccades achieve rapid refixation of targets that fall on the extrafoveal retina by moving the eyes at peak velocities that can exceed $700^{\circ}/s$. Various brain lesions can affect saccadic latency, velocity, or accuracy. Smooth pursuit maintains fixation of a slowly moving target. The pursuit system responds to slippage of an image near the fovea in order to accelerate the eyes to a velocity that matches that of the target. When smooth eye movements velocity fails to match target velocity, catch-up saccades are used to compensate for limited smooth pursuit velocities. The VOR subserves vision by generating conjugate eye movements that are equal and opposite to head movements. If the VOR gain (the ratio of eye velocity to head velocity) is too high or too low, the target image is off the fovea, and head motion causes oscillopsia, an illusory to-and-fro movement of the environment.

We present a novel method for eye location by means of a two-level classifier scheme. Locating the eye by machine-inspection of an image or video is an important problem for Computer Vision and is of particular value to applications in biomedical imaging. Our method aims to overcome the significant challenge of an eye-location that is able to maintain high accuracy by disregarding highly variable changes in the environment. A first level of computational analysis processes this image context. This is followed by object detection by means of a two-class discrimination classifier(second algorithmic level).We have tested our eye location system using FERET and BioID database. We compare the performance of two-level classifier with that of non-level classifier, and found it's better performance.

경기도와 강원도 소재의 대학생 221명을 대상으로 컬러렌즈 착용 유무에 따른 이미지 효과를 알아보기 위한 연구로서 시각적으로 나타나는 평가요인을 살펴보았고, 평가요인에 따른 이미지 효과의 차이 및 관련성을 알아보았다. 또한 컬러렌즈의 착용이 여성의 눈과 얼굴 이미지 변화에 어떠한 효과가 있는지 규명하고자 하였다. 컬러렌즈 착용 이미지에 대한 감성평가는 화려함, 매력적, 세련됨, 호감도 등을 의미하는 항목이 높게 인지됐지만, 미착용 이미지는 편안함, 부드러움, 청순함 등을 의미하는 항목이 높게 인지되었다. 평가 항목에 대한 요인분석을 실시하였을 때, 컬러렌즈 착용 이미지는 매력성, 청아함, 친숙성, 장식성 순으로 분류되었고, 컬러렌즈의 미착용 이미지는 친숙성, 매력성, 청아함, 장식성 순으로 분류되었다. 컬러렌즈를 착용한 눈의 장식적, 매력적, 청아한 요인은 눈과 얼굴 이미지를 변화된다고 인지하였다. 컬러렌즈 착용 유무의 각 요인과 이미지 효과의 상관관계를 분석한 결과, 착용 이미지에서는 장식적, 청아함, 매력적으로 인식할수록 눈과 얼굴 이미지를 변화시키는데 관련성이 있는 것으로 나타났다. 즉 컬러렌즈의 착용은 눈과 얼굴의 이미지가 매력적, 청아함, 장식적으로 보이는 효과가 있었으며, 이러한 컬러렌즈 착용 효과는 자신의 개성에 맞도록 눈과 얼굴 이미지를 보완하기 위한 중요한 표현 수단임을 알 수 있었다.

In this study, measuring eye movements with E.O.G. to targets beyond 20$^{\circ}$ from fixation point, results are as follows. (1) When the eyes turn toward targets of more than 20$^{\circ}$ eccentricity, the first saccadic eye movement falls short of the target. The presence of image of the target off the fovea(visual error signal) subsequent to such an undershoot elicits, after short interval, corrective saccadic eye movements(usually one) which place the image of the target on the fovea. (2) There are different programming modes at retina for eye movement to targets within and beyond 20$^{\circ}$ from the fixation point. (3) Saccadic system, preparing the direction and amplitude of eye movement completes the corrective saccadic eye movements. (4) Distribution of latency and intersaccadic interval(I.S.I.)are frequently multi modal, with a seperation between modes of 25[msec]. (5) There are two types of saccadic eye movements for the double-step targets. This fact suggests that the visual information is sampled stochastically. (6) The new model of saccadic system including the dissociation of visual functions dependent on retinal eccentricity is required.

이미지나 동영상은 텍스트보다도 많은 정보를 함축하고 있기 때문에 이를 추출해내고 분석하는 일은 매우 중요한 일이 되고 있다. 본 연구에서는 동영상에서 사람의 얼굴을 검출하고, 눈의 영역이 확인된 이미지를 이용하여 눈의 개폐와 눈동자의 위치를 판단하는 방법을 제시하였다. 색상을 흑백으로 양극화하고 수평화하여 이미지를 정규화한 후, 눈가의 수평, 수직의 모서리 점들을 파악하여 측정치를 얻어낸다. 이를 통하여 눈의 개폐와 눈동자의 위치를 판단한다. 동영상에서 얻어낸 임의의 52개의 눈 이미지를 실험대상으로 처리하여 눈의 개폐를 98% 검출하고 95%의 정확도로 눈동자 위치를 판단하는 실험결과를 얻었다.

In this paper, we present a fast face detection algorithm by estimating the eye region using neural network. To implement a real time face detection system, it is necessary to reduce search space. We limit the search space just to a few pairs of eye candidates. For the selection of them, we first isolate possible eye regions in the fast and robust way by modified histogram equalization. The eye candidates are paired to form an eye pair and each of the eye pair is estimated how close it is to a true eye pair in two aspects : One is how similar the two eye candidates are in shape and the other is how close each of them is to a true eye image A multi-layer perceptron neural network is used to find the eye candidate region's closeness to the true eye image. Just a few best candidates are then verified by eigenfaces. The experimental results show that this approach is fast and reliable. We achieved 94% detection rate with average 0.1 sec Processing time in Pentium III PC in the experiment on 424 gray scale images from MIT, Yale, and Yonsei databases.

In this study, we developed the drowziness prevention system to detect the driver's drowziness and relieve the driver. A computer vision method was proposed to detect the driver's drowziness. We extracted the eyes and mouth in the face image and tracked the positions from the image sequencies in real time. The eye blink duration and yawning was used as the parameters of drowziness. Wehn the drowziness state of a driver is detected, the driver is refreshed by the scent generator and the alarm. Also, the driver's bio-signal is acquired and analysed the vigilance state.
