Since the very beginning of space exploration, cosmonauts have suffered from weight losses which need to be particularly monitored during long term missions in space stations to insure their health and well being. In 1965–6 Thornton successfully built a device able to measure the body mass of cosmonauts in the micro-gravity space environment using passive linear spring-mass oscillators. Since then,...
A parametric mannequin modeling technology based on feature is presented. Differing from traditional human modeling methods, this one involves a feature-based parametric design ideas, feature parameters are determined according to anthropometry; Additionally, a parametric deformation algorithm based on free-form deformation also have been introduced. The remarkable advantages of this technology are...
3D anthropometric data can be obtained more easily than several years ago, but to process 3D data is most challenging and local feature extraction is one of the challenges. To extract local features of a landmark on 3D anthropometric data, numerous methods have been proposed. But the method with high efficiency, good robustness and strong adaptability is still not found out. In this paper, an approach...
Nowadays, multimodal human-like sensing, e.g. vision, haptics and audition seeks to improve interaction between an operator (human) and a teleoperator (robot) in human centered robotic systems. Head Related Transfer Function (HRTF) based sound rendering techniques, which seek to create a realistic virtual auditory space for listeners, have become a prominent concept in human robot interaction. Applications...
Three-dimensional (3D) anthropometric data can be obtained more easily in the last decades, and numerous applications can be realized by using 3D data. However, how to manage large scale 3D database is a most challenging task yet. In this paper, an information management system of 3D anthropometric data using GLScene, a Delphi open source widget based on OpenGL technique, was proposed. The data was...
We investigate the utility of ID anthropometric measurements as a biometric for human identification when the subject pose differs in probe and gallery data. Whereas previous studies simulated probe data by adding noise to 3D gallery data, prior to extracting 1D measurements, we use a large 3D full-body data set having multiple poses per subject. Our analysis of 27 measurements from 2,144 subjects...
The 3-D foot scanning technology has become an important application in foot studies of large scale recently. Nevertheless 3-D foot forms scanned usually consist of many holes because of missing views and grazing angle views. These holes are significant drawbacks of 3-D foot anthropometry. To overcome this problem, this study is to demonstrate a method to fill holes using template matching method...
Daily volume loss of the residual limp is reported as one of the greatest challenges in socket fitting. Assisted vacuum socket systems were developed to prevent stump's volume loss and maintain sufficient socket fit. There is however very little quantitative biomechanical research for the evaluation of below knee sockets with assisted vacuum systems. Highly accurate in-vivo measurements became recently...
This study presents a revolutionary computer-assisted surgery planning and simulating system under multimedia environment for the internal fixation operative of calcaneal collapse. This system uses the full-scale 3D reverse engineering technique in designing and developing preoperative planning modules for the internal fixation operative of calcaneal collapse. The planning system not only presents...
Three-dimensional (3D) anthropometry can provide rich shape information and will contribute fundamental part of many anthropometric, biological, anthropological, archaeological and botanical researches, etc. In this paper, typical challenges in the application of 3D anthropometry are highlighted, e.g. automatic landmark identification from 3D anthropometric data, shape comparison and analysis by using...
Computer-generated facial avatars have been increasingly used in a variety of virtual reality applications. Emulating the real-world face sculpting process, we present an interactive system to intuitively craft personalized 3D facial avatars by using 3D portrait editing and image example-based painting techniques. Starting from a default 3D face portrait, users can conveniently perform intuitive "pulling"...
In this paper we propose a new geometric method for 3D face recognition based on anthropometric measurements. 3D facial feature points are measured by stereovision and are used to construct a 3D signature containing distances, indices and angles between these points, in order to discriminate individuals. This approach is evaluated on the new IV2 database and results are presented an discussed.
In this paper, we derive a data mining framework to analyze 3D features on human faces. The framework leverages kernel density estimators, genetic algorithm and an information complexity criterion to identify discriminant feature-clusters of lower dimensionality. We apply this framework on human face anthropometry data of 32 features collected from each of the 300 3D face mesh models. The feature-subsets...
Following the success of SizeUK and SizeUSA, Thailand had embarked on its first National Sizing Survey (SizeThailand), to construct a major anthropometrics database of over 12,500 people. Using a 3D body scanning technology that takes less than 10 seconds per scan to capture a highly accurate 3D body image, from which hundreds of body measurements can be extracted, the survey was able to be conducted...
This paper presents a novel method for generating varied, realistic geometric face models by synthesizing facial features according to anthropometric parameters. Our method takes as examples scanned 3D face models in order to exploit the parameter-to-geometry correlations that are presented in the real faces. A two-step model fitting approach is used to establish correspondences among scanned models...
