Real human digital models appear more and more frequently in VR/AR application scenarios, in which real-time markerless face capture animation of personalized virtual human faces is an important research topic. The traditional way to achieve personalized real human facial animation requires multiple mature animation staff, and in practice, the complex process and difficult technology may bring obstacles to inexperienced users. This paper proposes a new process to solve this kind of work, which has the advantages of low cost and less time than the traditional production method. For the personalized real human face model obtained by 3D reconstruction technology, first, use R3ds Wrap to topology the model, then use Avatary to make 52 Blend-Shape model files suitable for AR-Kit, and finally realize real-time markerless face capture 3D real human on the UE4 platform facial motion capture, this study makes rational use of the advantages of software and proposes a more efficient workflow for real-time markerless facial motion capture of personalized 3D real human models, The process ideas proposed in this paper can be helpful for other scholars who study this kind of work.

A method of interactive human interface for motion modification of an articulated object model like a human body, a multiple joints robot, etc. has been developed, and implemented to a human body motion model. In the case of computer software models, the initial data setting for overall motion is rather easy. However, modifying or correcting the initially set motion is rather difficult for keeping consistency. In this research, the requirements shown below have mainly been set as the specifications ...

With the continuous development of deep learning, human behavior recognition algorithms have achieved good results. However, in a multi-person recognition environment, the complex behavior environment poses a great challenge to the efficiency of recognition. To this end, this paper proposes a multi-person pose estimation model. First of all, the human detectors in the top-down framework mostly use the two-stage target detection model, which runs slow down. The single-stage YOLOv3 target detection model is used to effectively improve the running speed and the generalization of the model. Depth separable convolution, which further improves the speed of target detection and improves the model's ability to extract target proposed regions; Secondly, based on the feature pyramid network combined with context semantic information in the pose estimation model, the OHEM algorithm is used to solve difficult key point detection problems, and the accuracy of multi-person pose estimation is improved; Finally, the Euclidean distance is used to calculate the spatial distance between key points, to determine the similarity of postures in the frame, and to eliminate redundant postures.

얼굴 표정은 사람의 감정을 전달하는 핵심 메커니즘으로 이를 적절하게 활용할 경우 Robotics의 HRI(Human Robot Interface)와 같은 Human Computer Interaction에서 큰 역할을 수행할 수 있다. 이는 HCI(Human Computing Interface)에서 사용자의 감정 상태에 대응되는 다양한 반응을 유도할 수 있으며, 이를 통해 사람의 감정을 통해 로봇과 같은 서비스 에이전트가 사용자에게 제공할 적절한 서비스를 추론할 수 있도록 하는 핵심요소가 된다. 본 논문에서는 얼굴표정에서의 감정표현을 인식하기 위한 방법으로 FACS(Facial Action Coding System)와 AAM(Active Appearance Model)을 이용한 특징 추출과 Bayesian Network 기반 표정 추론 기법이 융합된 얼굴표정 인식 시스템의 개발에 대한 내용을 제시한다.

본 논문의 목적은 기업 신용점수에 영향을 미치는 기업 인적자원 요소들을 찾아서 기업 신용점수 모형을 구축하는 것이다. 모형 구축을 위해 사용된 자료는 2005년 한국직업능력개발원의 인적자본 기업패널 (Human Capital Corporate Panel, HCCP) 설문조사 자료와 한국신용평가(주)의 KIS-신용평점모델에서 생성된 기업 신용점수이다. 모형 구축을 위한 독립변수는 McLagan (1989)의 '인적자원 바퀴모델'을 토대로 인적자본 기업패널 설문조사 문항을 선택하여 사용하였으며, 종속변수로는 기업 신용평가점수를 사용하였다. 또한 기업 인적자원 관련 변수를 이용한 기업 신용점수 모형 구축을 위해 로지스틱 회귀모형을 사용하였다. 모형 구축 결과 최종적으로 선택된 변수는 22개였다 영역별로 세분화해서 살펴보면 대분류 기준으로 HRD 영역은 6개, HRM 영역은 15개, 기타 1개이고, 중분류 기준으로 개인개발 2개, 경력개발 2개, 조직개발 2개, 조직직무설계 1개, 인적자원계획 4개, 정보체계 2개, 보상 및 장려 6개, 복지후생 1개, 노사관계 1개, 기업규모 1개가 선택되었다. 구축된 모형을 평가하기 위하여 10등급 교차타당성 분석을 통한 오분류율, G-mean은 각각 30.81, 68.27이었다. 그리고 반응율은 가장 좋은 십분위가 가장 나쁜 십분위보다 약 6.08배가 크고 점차 감소하는 경향을 보이고 있다. 그러므로 구축된 모형은 기업 인적자원 관련 변수를 이용해 기업 신용점수를 측정하는데 적당한 모형이라는 결론을 내릴 수 있다

This study presents the eigen ethnic function and mathematical processing method of human information. Human information can be definded as the overlap area taking the superposition property composed of intuition and sensory in stimulus/response (S/R) model, In S/R model, the intuition and sensory eigen ethnic function acts on the forming of perception. Perception process by the superposition property of intuition and sensory analogy to the basic neural network model. This analogy model extends to the analysis method. As an analysis method, optimal ratio number induced to the golden section ratio. Golden section ratio drived out by diverse source and implicated to the sensory and intuitive context such as beauty, harmony, optimality etc. This numerical orders can be applied to analysing the Perception process and extended to pursue the Potential human behavior, On the basic of proposed applying method, an illustrative mathematical examples are presented.

The purpose of this paper is to develop a 3-dimensional human model, an ergonomic CAD (Computer-Aided Design) system which would be very helphul in ergonomic design. An interactive program was developed, in which a user could change layout, body size, skin volume, and posture of the human model. As an example, effect of inclination of a steering wheel on visibility of a display panel was demonstrated. he result showed that ergonomic design can be aided by the 3-dimensional human model, and by the perspective graph by which design and evaluation process can be carried out more effectively.

This paper aims to provide a multi-dimensional integrative model that can give a comprehensive account for human space experience. Human space experience is too complicated phenomenon, so space designer need to understand about mechanism of space cognition. From psychological point of view, I analyze the mechanism that is based on emotional reaction. This model consist of three dimensions: sensory, reflexive, and reflective dimension. Assuming this model, we have attempt the typological analysis to the space by studying human space experience. Finally, the outcome provides how space designer use this effect for application of human experience.

The water content of skin was determined using a FT near infrared (NIR) spectrometer. NIR diffuse reflectance spectra were collected from hairless mouse, in vitro, and from human inner arm, in vivo. It was found that the variation of NIR absorbance band 1450 nm from OH vibration of water and 1940 nm from the combination involving OH stretching and OH deformation, depending on the absolute water content of separated hairless mouse skin, in vitro, using the FT NIR spectrometer. Partial least squares regression (PLSR) was applied to develop a calibration model. The PLS model showed good correlation. For practical use of the evaluation of human skin moisture, the PLS model for human skin moisture was developed in vivo on the basis of the relative water content of stratum corneum from the conventional capacitance method. The PLS model predicted human skin moisture with a standard errors of prediction (SEP) of 3.98 at 1130-1830 nm range. These studies showed the possibility of a rapid and nondestructive skin moisture measurement using FT NIR spectrometer.
