  • Purpose: The purpose of this study was to examine the effects of a facial muscle exercise program including facial massage on the facial muscle function, subjective symptoms related to paralysis and depression in patients with facial palsy. Methods: This study was a quasi-experimental research with a non-equivalent control group non-synchronized design. Participants were 70 patients with facial palsy (experimental group 35, control group 35). For the experimental group, the facial muscular exercise program including facial massage was performed 20 minutes a day, 3 times a week for two weeks. Data were analyzed using descriptive statistics, ${\chi}^2$-test, Fisher's exact test and independent sample t-test with the SPSS 18.0 program. Results: Facial muscular function of the experimental group improved significantly compared to the control group. There was no significant difference in symptoms related to paralysis between the experimental group and control group. The level of depression in the experimental group was significantly lower than the control group. Conclusion: Results suggest that a facial muscle exercise program including facial massage is an effective nursing intervention to improve facial muscle function and decrease depression in patients with facial palsy.

  • Muscle based face image synthesis is one of the most realistic approach to realize life-like agent in computer. Facial muscle model is composed of facial tissue elements and muscles. In this model, forces are calculated effecting facial tissue element by contraction of each muscle strength, so the combination of each muscle parameter decide a specific facial expression. Now each muscle parameter is decided on trial and error procedure comparing the sample photograph and generated image using our Muscle-Editor to generate a specific face image. In this paper, we propose the strategy of automatic estimation of facial muscle parameters from 2D marker movement using neural network. This also 3D motion estimation from 2D point or flow information in captered image under restriction of physics based face model.

  • Recent reports have described several cases of double muscle transfers to restore natural, symmetrical smiles in patients with long-standing facial paralysis. However, these complex procedures sometimes result in cheek bulkiness owing to the double muscle transfer. We present the case of a 67-year-old woman with long-standing facial paralysis, who underwent two-stage facial reanimation using two superficial subslips of the serratus anterior muscle innervated by the masseteric and contralateral facial nerves via a sural nerve graft. Each muscle subslip was transferred to the upper lip and oral commissures, which were oriented in different directions. Furthermore, a horizontal fascia lata graft was added at the lower lip to prevent deformities such as lower lip elongation and deviation. Voluntary contraction was noted at roughly 4 months, and a spontaneous smile without biting was noted 8 months postoperatively. At 18 months after surgery, the patient demonstrated a spontaneous symmetrical smile with adequate excursion of the lower lip, upper lip, and oral commissure, without cheek bulkiness. Dual-innervated muscle transfer using two multivector superficial subslips of the serratus anterior muscle may be a good option for long-standing facial paralysis, as it can achieve a symmetrical smile that can be performed voluntarily and spontaneously.

  • The purpose of this study was to estimate skin care effect of Miso Facial Rejuvenation Acupuncture with the facial skin photographing system and ultrasonography. 4 Patients who made first visits to Daegu Oriental Hospital of Daegu Hanny University from August 7, 2009 to August 12, 2009 were each given five-times treatments of Miso Facial Rejuvenation Acupunture. The facial skin photography of each participant was checked two times-pretreatment, posttreatment-using the facial skin photographing system and ultrasonography. The squares and counts of 2parts of facial winkles and thickness of masseter muscle were measured for each one. The squares and counts of facial wrinkles were decreased. The thickness of masseter muscle were decreased. On this study, we could evaluate the wrinkle treatment effects and reduction of masseter muscle of Miso Facial Rejuvenation Acupuncture by an objective method. Miso Facial Rejuvenation Acupuncture has notable effect in wrinkle treatment and reduction of masseter muscle. As though we had not wide experience in this treatment, more research is needed.

  • Background Temporalis muscle transfer produces prompt surgical results with a one-stage operation in facial palsy patients. The orthodromic method is surgically simple, and the vector of muscle action is similar to the temporalis muscle action direction. This article describes transferring temporalis muscle insertion to reconstruct incomplete facial nerve palsy patients. Methods Between August 2009 and November 2011, 6 unilateral incomplete facial nerve palsy patients underwent surgery for orthodromic temporalis muscle transfer. A preauricular incision was performed to expose the mandibular coronoid process. Using a saw, the coronoid process was transected. Three strips of the fascia lata were anchored to the muscle of the nasolabial fold through subcutaneous tunneling. The tension of the strips was adjusted by observing the shape of the nasolabial fold. When optimal tension was achieved, the temporalis muscle was sutured to the strips. The surgical results were assessed by comparing pre- and postoperative photographs. Three independent observers evaluated the photographs. Results The symmetry of the mouth corner was improved in the resting state, and movement of the oral commissure was enhanced in facial animation after surgery. Conclusions The orthodromic transfer of temporalis muscle technique can produce prompt results by applying the natural temporalis muscle vector. This technique preserves residual facial nerve function in incomplete facial nerve palsy patients and produces satisfying cosmetic outcomes without malar muscle bulging, which often occurs in the turn-over technique.

  • 얼굴 표정은 상호간 의사소통에 있어 중요한 의미를 갖는 것으로, 인간이 사용하는 다양한 언어보다도 수많은 인간 내면의 감정을 표현할 수 있는 유일한 수단이다. 본 논문에서는 쉽고 자연스러운 얼굴 표정 생성을 위한 근육 모델 기반 3D 얼굴 표정 생성 시스템을 제안한다. 3D 얼굴 모델의 표정 생성을 위하여 Waters의 근육 모델을 기반으로 자연스러운 얼굴 표정 생성에 필요한 근육을 추가하여 사용하고, 표정 생성의 핵심적 요소인 눈썹, 눈, 코, 입, 볼 등의 특징요소들을 중심으로 얼굴 근육과 근육벡터를 이용하여 해부학적으로 서로 연결된 얼굴 근육 움직임의 그룹화를 통해 얼굴 표정 변화의 기본 단위인 AU를 단순화하고 재구성함으로써 쉽고 자연스러운 얼굴 표정을 생성할 수 있도록 하였다.

  • 컴퓨터 분야에서 얼굴근육 이미지합성은 살아있는 것 같은 모델을 실현하기 위한 가장 실재적인 접근방법 중의 하나이며, 얼굴근육 모델은 얼굴조직 성분과 근육으로 구성된다. 이 모델에서 얼굴 조직 성분에 영향을 주는 힘(force)은 각 근육의 수축강도로써 계산되어지고, 각 근육 파라메터의 결합은 명확한 얼굴표현으로 결정한다. 또한 각 근육 파라메터는 실험과 샘플 사진과 근육편집기로 생성한 명확한 이미지를 비유하여 에러처리과정을 통해 결정된다. 이 논문에서 신경회로망을 사용한 2D(Two-Dimension) 지시점의 움직임으로부터 얼굴근육의 자동인식 방법을 제안하고자 하며, 얼굴모델을 기반으로 한 물리학적 제한하에 캡처된 이미지에서 정보 흐름과 2D 포인트로부터 3D(Three-Dimension) 움직임 인식을 하고자 한다.

  • Facial rigging technology has been developing more and more since the 21st century. Facial rigging of various methods is still attempted and a technique of capturing the geometry in real time recently also appears. Currently Modern CG is produced image which is hard to distinguish from actual photograph. However, this kind of technology still requires a lot of equipment and cost. The purpose of this study is to perform facial rigging using muscle simulation instead of using such equipment. Original muscle simulations were made primarily for use in the body of a creature. In this study, however, we use muscle simulations for facial rigging to create a more realistic creature-like effect. To do this, we used Ziva Dynamics' Ziva VFX muscle simulation software. We also develop a method to overcome the disadvantages of muscle simulation. Muscle simulation can not be applied in real time and it takes time to simulate. It also takes a long time to work because the complex muscles must be connected. Our study have solved this problem using blendshape and we want to show you how to apply our method to face rig.

  • 본 논문에서는 얼굴의 표정 변화에 영향을 주는 해부학에 기반한 18개의 근육군쌍을 바탕으로 하여 얼굴 표정 애니메이션을 위한 근육의 움직임을 조합할 수 있도록 하였다. 개인의 이미지에 맞춰 메쉬를 변형하여 표준 모델을 만든 다음, 사실감을 높이기 위해 개인 얼굴의 정면과 측면 2장의 이미지를 이용하여 메쉬에 매핑하였다. 얼굴의 표정 생성을 애니메이션 할 수 있는 원동력이 되는 근육 모델은 Waters의 근육모델을 수정하여 사용하였다. 이러한 방법을 사용하여 텍스처가 입혀진 변형된 얼굴을 생성하였다. 또한, Ekman이 제안한 6가지 얼굴 표정을 애니메이션 하였다.
