The recent breakthroughs of multimedia computing have expanded its scope of application to the fields not been touched before. The reproduction of late artists' performance, especially dancers', which had put on the back burner until now, also beginning to shed the light. This study showed how to apply it to the reproduction of these late performers. Through this work, not only did we reduce the working time by applying the software to the manual process which has been dominantly practiced for reproducing the existing stage, but also made it possible to be reused in the subsequent work.

Foreign body (FB) impaction in the maxillofacial area could be caused by knives, glass fragments, and vegetative materials. We present the rare case of a 62-year-old man with a large glass FB in the left cheek retained for over 40 years. He had traffic accident over 40 years ago and glass fragments impacted on his left cheek. Glass fragments were retained around the zygomatic arch with dimpled scar and unclear serous discharge, but other facial motor or sensory dysfunction was not observed. We confirmed three glass fragments with radiologic examination including plain radiograph and computed tomographic image. Under general anesthesia, impacted glass fragments were removed through the direct incision on the dimpled scar and the additional incision on the left lateral canthal area. Remnant FBs were not seen on an intraoperative C-arm radiograph. After 2 days of irrigation for inflammation control, the dimpled wound was sutured. The wound was healed without major complication and the original dimpled scar was much improved.

In this paper we propose a new algorithm to detect the irises of both eyes from a human face. Using the separability filter, the algorithm first extracts blobs(intensity valleys) as the candidates for the irises. Next, for each pair of blobs. the algorithm computes a cost usings Hough transform and separability later to measure the fit of the pair of blobs to the image. And then, the algorithm selects a pair of blobs with the smallest cost as the irises of both eyes. As the result of the experiment using 150 faces images without spectacles, the success rate of the proposed algorithm was 97.3% for the best case and 95.3% for the worst case.

The purpose of this study was to understand the effects of religion on Amish costumes. For this study I twice visited Amish village in Lancaster Pennsylvania U.S,A in July 1993 and August 1996. The methods of study directed direct observation and literature re-search. The results of this study were as follows: The Amish was livid practically by strict princi- ples of simplicity diligence piety and mutual cooperation. The Amish behavioral code of laws known as ordnung dictated appropriate dress agricultual methods and a routine for daily life. The Amish costumes originated with the 17th century Puritans traditional apparel the European farmer and the clothing style of 19th century Americal,. Amish costumes was fastened with hooks and eyes instead of decorative buttons a diret influence of Puritanism does and did non con-tain ornamental outer pockets. This distinctively simple costumes served as a boundary outsiders to and as a direct ex-pression of their faith. An Amish doll had neither facial features nor fingers and toes as described in scripture "You do not become corrupt and make for yourselves an idol an image of any shape whether formed like a man or a women or like any animal on earth or any bird that flies in the air or like any creature that moves along the ground or any fish in the waters below" In this way Amish costumes was affected by their religion and faith.

We proposed a method for locating of mouth using deformable templates, described by a parameterized template. An energy function is defined which links, edges, peaks, valleys in image intensity to corresponding properties of the template. The template deforms itself by altering its parameter values to minimize the energy function. The minimized energy function's parameter values can be used as descriptors for the feature. We propose a method for locating mouth fast, accurately by limiting a range of parameters' value and getting initial value of parameters' by preprocessing.

얼굴의 표정은 얼굴의 구성요소 같은 기하학적 정보와 조명이나 주름 같은 세부적인 정보들로 표현된다. 얼굴 표정은 기하학적 변형만으로는 실감적인 표정을 생성하기 힘들기 때문에 기하학적 변형과 더불어 텍스쳐 같은 세부적인 정보도 함께 변형해야만 실감적인 표현을 할 수 있다. 표정비율이미지 (Expression Ratio Image)같은 얼굴 텍스처의 세부적인 정보를 변형하기 위한 기존 방법들은 조명에 따른 피부색의 변화를 정확히 표현할 수 없는 단점이 있다. 따라서 본 논문에서는 이러한 문제를 해결하기 위해 서로 다른 조명 조건에서도 실감적인 표정 텍스처 정보를 적용할 수 있는 비선형 피부색 모델 기반의 표정 합성 방법을 제안한다. 제안된 방법은 동적 외양 모델을 이용한 자동적인 얼굴 특징 추출과 와핑을 통한 표정 변형 단계, 비선형 피부색 변화 모델을 이용한 표정 생성 단계, Euclidean Distance Transform (EDT)에 의해 계산된 혼합 비율을 사용한 원본 얼굴 영상과 생성된 표정의 합성 등 총 3 단계로 구성된다. 실험결과는 제안된 방법이 다양한 조명조건에서도 자연스럽고 실감적인 표정을 표현한다는 것을 보인다.

Transverse myelitis is a focal inflammatory disorder of the spinal cord characterized by motor, sensory, and autonomic dysfunction. A 41-year-old man with transverse myelitis and no pre-existing neurologic disease presented with hypesthesia, numbness, weakness in the both lower extremities, back pain, decreased libido, constipation, and dysuria. A MRI test showed intramedullary high signal intensity between T4 and T8 on a T2-weighted image. After high-dose intravenous methylprednisolone and oral prednisolone therapy, he showed facial swelling and acneiform eruption. Therefore, we injected 40 mg methylprednisolone via an epidural route. A 7-dose serial treatment improved most symptoms. A follow up MRI showed radiological improvement. We report a case of transverse myelitis treated by epidural steroids.

In this paper, we propose an interactive system that generates emotional expressions from arm gestures. By extracting relevant features from key frames, we can infer emotions from arm gestures. The necessary factor for real-time animation is tremendous frame rates. Thus, we propose processing facial emotion expression with 3D application for minimizing animation time. And we propose a method for matching frames and actions. By matching image sequences of exagerrated arm gestures from participants, they feel that they are communicating directly with the portraits.

This paper addresses a method of estimating roughly the human pose by comparing Haar-wavelet value which is learned in face detection technology using AdaBoost algorithm. We also presents its application to face recognition. The learned weak classifier is used to a Haar-wavelet robust to each pose's feature by comparing the coefficients during the process of face detection. The Mahalanobis distance is used to measure the matching degree in Haar-wavelet selection. When a facial image is detected using the selected Haar-wavelet, the pose is estimated. The proposed pose estimation can be used to improve face recognition speed. Experiments are conducted to evaluate the performance of the proposed method for pose estimation.

This paper discusses low resolution face recognition using the photon-counting linear discriminant analysis (LDA). The photon-counting LDA asymptotically realizes the Fisher criterion without dimensionality reduction since it does not suffer from the singularity problem of the fisher LDA. The linear discriminant function for optimal projection is determined in high dimensional space to classify unknown objects, thus, it is more efficient in dealing with low resolution facial images as well as conventional face distortions. The simulation results show that the proposed method is superior to Eigen face and Fisher face in terms of the accuracy and false alarm rates.
