홍채인식 시스템의 성능은 입력된 눈 영상으로부터 정확한 홍채 영역의 검출 및 효율적인 홍채코드의 생성 등의 영향을 받으나, 이를 위해서는 입력된 눈 영상에서 홍채 패턴이 선명해야 한다는 선행 조건이 존재한다. 초점이 맞지 않아 흐리게 나온 영상 눈을 감은 영상, 속눈썹에 의해 홍채영역이 가려진 영상, 움직임에 의해 블러링된 영상, 또는 홍채가 아닌 속눈썹 등의 다른 부분에 초점이 맞춰진 영상 등에서는 선명한 홍채 패턴을 얻을 수 없으므로 전체 인식 성능을 떨어뜨리는 요인이 된다. 그러므로 이러한 영상들을 자동으로 걸러내 제거해주는 눈 영상 화질 측정 방법이 필요하다. 본 논문에서는 눈 영상의 초점이 잘 맞는지 측정하는 방법을 제안하고 자체적으로 획득한 데이터베이스를 이용해 이를 테스트하였다.

옛말에 몸이 천냥이면 눈이 구백냥이라는 말이 있다. 그만큼 눈이 중요하다는 말이다. 이처럼 중요한 눈을 보호하기 위해 우리 몸은 눈을 보호하는 구조로 되어 있다. 위로는 머리뼈가 앞으로는 코뼈, 밖으로는 광대뼈가 철저하게 보호하고 있으며, 만약 외보로부터 눈으로 뭇엇이 날아오면 눈꺼풀과 속눈썹이 반사적으로 반응하여 눈을 감아 외부로부터 눈을 보호한다. 하지만 이런 보호 속에서도 눈은 혹사당하고, 시력이 점점 떨어지는 경우가 많다. 눈은 하루아침에 급격히 나빠지지 않지만 한 번 나빠지면 다시 회복하기가 쉽지 않다. 평소 건강한 눈을 위한 관리법에서 시력을 회복시켜주는 수술까지 눈에 대한 A to Z를 알아본다.

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.

The purpose of this study was to examine the need of the eyelash design area and the changes of an eye image according to eyelash design. Methodology included both a theoretical research and an empirical research. The theoretical research reviewed previous researches and technical books. The empirical research divided eye shapes, complemented the defect of eye shapes, and examined resulting image changes. A mechanical way was performed for treatment because it was more efficient than a manual way. A J-curl type was used. Eye length was divided into five and the point was determined. The length and density of curl were changed in each point to maximize a treatment effect. As a result, eye images were changed as follows. First, round eyes became stable. Slit eyes became vivid and soft. Wide-set eyes became intelligent and narrow-set eyes became smooth. Large eyes were naturally gradated and small eyes became larger. Double-eyelid eyes became stable and elegant and single-eyelid eyes became gentle and soft. Bulging eyes became easy and soft and sunken eyes became smooth. Peaked eyes became gentle and soft and sleepy eyes became strong and vivid. Based on the findings, eyelash design can play a role in changing an image according to eye shapes. In particular, a speed eyelash extension device to extend eyelash can reduce working hours and gradate only by angle control. It can complement the defect of eyes according to the design of each shape and change into a better image.

Cornelia de Lange syndrome is a dysmorphogenic disorder characterized by multiple congenital abnormalities, mental retardation, growth retardation and neurodevelopmental abnormalities. Diagnosis for the Cornelia de Lange syndrome is dependent on the clinical observation because neither definite biological marker nor definite chromosomal abnormality have been investigated. Clinical observation is important for the diagnosis, so we report a case of Corenelia de Lange syndrome with mental retardation and autistic disorder. The patient is a 6-year old girl. Her motor development and language development have been delayed. She could say no meaningful word and understood simple command partially. She showed poor eye contact and poor emotional interaction. Social interaction was impaired and she Showed stereotypic behaviors. Thus we diagnosed her as mental retardation with autistic disorder. She had vesicoureteral reflux, frequent upper respiratory infection and pneumonia. She had experienced febrile convulsions 4 times. She had short stature, confluent eyebrows, long eyelashes, and upturned nose with anteverted nostrils. She also showed low hairline and hypertrichosis in body and extremities. Her finger was short. In this case, we diagnosed Cornelia de Lange syndrome by her characteristic face, hypertrichosis and medical and behavioral problems that were frequently showed in this syndrome.

Iris recognition is biometric technology which uses a unique iris pattern of user in order to identify person. In the captured iris image by conventional iris recognition camera, it is often the case with eyelid occlusion, which covers iris information. The eyelids are unnecessary information that causes bad recognition performance, so this paper proposes robust algorithm in order to detect eyelid. This research has following three advantages compared to previous works. First, we remove the detected eyelash and specular reflection by linear interpolation method because they act as noise factors when locating eyelid. Second, we detect the candidate points of eyelid by using mask in limited eyelid searching area, which is determined by searching the cross position of eyelid and the outer boundary of iris. And our proposed algorithm detects eyelid by using parabolic hough transform based on the detected candidate points. Third, there have been many researches to detect eyelid, but they did not consider the rotation of eyelid in an iris image. Whereas, we consider the rotation factor in parabolic hough transform to overcome such problem. We tested our algorithm with CASIA Database. As the experimental results, the detection accuracy were 90.82% and 96.47% in case of detecting upper and lower eyelid, respectively.
