  • Objectives : Trauma patients have attentional bias which enforces traumatic memories and causes cognitive errors. Understanding of such selective attention may explain many aspects of the posttraumatic stress disorder(PTSD) symptoms. Methods : We used the rapid serial visual presentation(RSVP) method to verify attentional blink in burn patients with PTSD. International affective picture system(IAPS) was used as stimuli and distracters. In the 'neutral test', patients have been presented series of pictures with human face picture as target stimuli. Each picture had 100ms interval. However the distance between target facial pictures was randomized and recognition of second facial picture accuracy was measured. In the 'stress test', the first target was stress picture which arouses patient emotions instead of the facial picture. Neutral and Stress tests were done with seven PTSD patients and 20 controls. In '85ms test' the interval was reduced to 85ms. The accuracy of recognition of second target facial picture was rated in all three tests. Eighty-five ms study was done with eighteen PTSD patients. Results : Attentional blinks were observed in 100-400ms of RSVP. PTSD patients showed increased recognition rate in the 'stress test' compared with the 'neutral test'. When presentation interval was decreased to 85 ms, PTSD patient showed decrease of attentional blink effect when target facial picture interval was 170ms. Conclusion : We found attentional blink effect could be affected by stress stimulus in burn patients. And attentional blink may be affected by stimulus interval and the character of stimulus. There may be some other specific mechanism related with selective attention in attentional blink especially with facial picture processing.

  • Objectives : This study was designed to evaluate the effect of Jung-an acupuncture on the sequelae of peripheral facial palsy. Methods : Four patients suffering from sequelae of peripheral facial palsy were treated with Jung-an acupuncture. Yanagihara's total scores, the scale of Peitersen grades and picture, before and after the Jung-an acupuncture treatment were compared to evaluate its treatment efficacy. Results : Yanagihara's total score of all subjects were increased. Peitersen grades of all subjects were decreased. Conclusions : As indicated by unequivocal increase in all subjects' Yanagihara and Peitersen scores, Jung-an Acupuncture treatment is effective in alleviating the sequelae of peripheral facial palsy. Randomized-controlled trial for further evaluation is necessary to verify the results and findings of this study.

  • Objectives : This study was performed to evaluate the effect of facial rejuvenation acupuncture on cases of sequela of facial nerve palsy. Methods : This study was carried out in respect of 5 cases of sequela of facial nerve palsy patients which had been treated in Dong-Shin university oriental hospital from 2009 year with House-Brackmann grading system(HBGS) above Grade IV. In this study the patients were treated by facial rejuvenation acupuncture. The effect of the treatment were evaluated via scales and picture. Results : After treatment with facial rejuvenation acupuncture, 5 patients improved H-B scale and symptoms of the sequela of facial nerve palsy. The average of H-B scale was increased from 3.2 to 6.4. There also formed forehead folds, better blinking of the eyes and improved asymmetry of the left and right face. Conclusions : In the study, facial rejuvenation acupuncture showed marked improvement in sequela of facial nerve palsy. Randomized-controlled trial for further evaluation will be needed in the future.

  • In this paper we propose a 3D emotional expression method using a comic model for effective sign-language communications. Until now we have investigated to produce more realistic facial and emotional expression. When representing only emotional expression, however, a comic expression could be better than the real picture of a face. The comic face is a comic-style expression model in which almost components except the necessary parts like eyebrows, eyes, nose and mouth are discarded. We represent emotional expression using Action Units(AU) of Facial Action Coding System(FACS). Experimental results show a possibility that the proposed method could be used efficiently for sign-language image communications.

  • 하드웨어의 급속한 기술발전은 3차원 영상정보를 포함한 다양한 디지털 영상정보의 급속한 발전과 확대를 가져왔다. 애니메이션, 가상현실, 영화, 광고, 게임 분야에서도 3차원 디지털 영상처리는 매우 다양하고 광범위하게 사용되고 있다. 이러한 3차원 디지털 영상 속에 등장하는 3D캐릭터는 의인화된 동작이나 음성, 표정등을 통해 관객에게 감동과 정보를 전달하는 중요한 역할을 담당한다. 3D캐릭터의 활용도와 사용범위가 확대되어감에 따라 효과적인 3D캐릭터의 동작연구나 표정연출에 대한 관심도 또한 높아지고 있다. 본 연구에서는 내적감정상태의 효과적 수단으로 사용되는 표정에 대해 연구해본다. 해부학적 구조에 기반한 얼굴근육의 운동방향과 변화에 따른 3D 캐릭터의 표정구현에 대해 살펴보고 효과적인 표현방법을 모색해보고자 한다. 또한 선행연구로 진행된 2D캐릭터 표정연구와의 비교를 통하여 그 차이점과 특징에 대해 살펴보고자 한다.

  • 본 논문은 사용자 사진에서 ASM(Active Shape Model)을 이용하여 얼굴의 각 특징 점을 추출하고, 추출 된 특징점을 이용하여 화장할 부분의 영역을 생성 한다. 기존의 가상 메이크업 프로그램에서는 사용자가 수동적으로 몇 개의 특징 점을 정확히 선택해야 하는데서 불편함을 초래했다. 본 논문에서 제안하는 가상 메이크업 프로그램에서는 ASM을 이용하여 사용자의 입력을 필요로 하지 않는다. 자연스러운 화장 효과를 표현하기 위해서 기본적인 알파 블렌딩을 각각 화장품의 특징에 맞게 변형하여 사용자 피부색과 화장품의 색을 혼합한다. 얼굴 윤곽, 눈, 눈썹, 입술, 볼의 영역을 생성하고, Foundation, Blush, Lip Stick, Lip Liner, Eye Pencil, Eye Liner, Eye Shadow 종류의 화장을 할 수 있게 구현하였다.

  • 본 논문에서는 실시간으로 입력되는 동영상으로부터 영상 내에 존재하는 사람의 얼굴 및 얼굴 특징점들을 자동으로 추출한 후, 추출된 정보를 이용하여 3차원 얼굴 모델의 표정을 실시간으로 제어함으로써 현실감 있는 얼굴 애니메이션 처리가 가능한 새로운 방법을 제시한다. 입력 영상의 각 프레임으로부터 얼굴을 효과적으로 추출하기 위해 기존에 일반적으로 사용되는 색상 공간을 이용한 파라미터 검출 방법에 대변되는 새로운 비파라미터 검출 방법을 제시하였다. 기존의 파라미터 검출 방법은 일반적으로 얼굴의 피부 색상분포를 가우지언 형태로 표현하며 특히 주변조명의 변화 및 배경 영상 등에 민감하게 반응하므로 정화한 영역의 검출을 위한 부가적 작업을 필요로 한다. 이러한 문제점을 효과적으로 해결하기 위하여 본 논문에서는 Hue와 Tint 색상 성분에 기반을 둔 새로운 스킨 색상 공간을 제시하고 모델의 분포특성을 직선 형식으로 표현하여 얼굴검출 시 발생되는 오류를 축소시킬 수 있었다. 또한, 검출된 얼굴 영역으로부터 정확한 얼굴특성 정보를 추출하기 위하여 각 특징영역에 대한 에지검색 결과와 얼굴의 비율 비를 적용하여 효과적으로 얼굴의 특징 영역을 검출하였다. 추출된 얼굴 특징점 변화 정보는 3차원 얼굴 모델의 실시간 표정 변화에 적용되며, 보다 실감 있는 얼굴 표정을 생성하기위하여 사람의 근육 정보와 근육의 움직이는 방법을 나타내는 Waters의 선형 근육 모델에 새로운 근육 정보들을 새롭게 추가함으로써 화장 적용하였다. 실험결과 제안된 방법을 이용하여 실시간으로 입력되는 대상의 얼굴표정을 3차원 얼굴 모델에 자연스럽게 표현할 수 있다.

  • 1. Objective This research looks into the facial characteristics of Sasang constitution. 2. Methods It assigns and measures the length of nine areas of the face using a picture, and calculates the proportions and gives statistical data of these items. It also references the proportion of the items using the contents of "Sanghakjinjeon" ("相學眞傳") Ten face-types as a basis, divides the face into seven types, looks into the similarities between constitutions, and also compares it to clinically and frequently used constitutional facial characteristics. 3. Results and Conclusion After comparing the analytical items between Taeumins, Soyangins, and Soeumins, Soeumins had an oval face due to the fact that the length and width that their lower faces took up was small compared to the entire face. After dividing the facial characteristics of the test subjects using 十字相, there were significantly more Taeumins in Dong(同)_face-type, and Soeumins in Won(圓)_face-type. There weren't any significant group that Soyangins showed up in. After comparing these facial characteristics with that of previous facial characteristics found in books and used clinically, we were able to find corresponding items.
