An infinite number of deformations exist for a given face mesh that can result in different shapes ranging from the realistic facial geometries to implausible appearances. In these systems, deformation settings are specified manually over the range of possible deformation for hundreds of vertices in order to achieve desired results. Some authoring tools for character modeling and animation are available (e.g., Maya, Poser, DazStudio, PeoplePutty ). Applications of such a system range from entertainment to communications: virtual human faces need to be generated for movies, computer games, advertisements, or other virtual environments, and facial avatars are needed for video teleconference and other instant communication programs. One of the most challenging tasks in graphics modeling is to build an interactive system that allows users to model varied, realistic geometric models of human faces quickly and easily. Of subjects in different race groups, facial feature transfer,Īnd adapting face models to a particular population group. Several applications, including analysis of facial features We demonstrate the utility of our method by presenting The new face shape can be generated at an interactive Shape that satisfies the user-specified constraints. In a reduced subspace allows us to generate a natural face The face modeling problem in a scattered data interpolationįramework which takes the user-specified anthropometric Using PCA coefficientsĪs a compact shape representation, we formulate For each facial feature, we computeĪ set of anthropometric measurements to parameterize theĮxample meshes into a measurement space. Of example meshes of facial features using principal componentĪnalysis (PCA) and uses it to regulate the naturalness The systemĪutomatically learns a model prior from the data-sets Presented in the real faces of individuals. Takes 3D face scans as examples in order to exploit the variations Procedures for interactive 3D face modeling and editing. Our methodĮstablishes an intuitive and efficient interface to facilitate These advances in anthropometric science and computer-based human-form modeling have opened various research avenues for improving workplace and protective equipment design as well as anthropometric fit within complex systems.This paper presents a new anthropometrics-based methodįor generating realistic, controllable face models. Also, computer-generated human models are now available for anthropometric analysis. Technological development in recent years has advanced the basic science of human size and shape studies in 3-dimensional forms (3D). This approach was successful in generating broad parameters for personal protective equipment (PPE) sizing but was deficient in generating the detailed fit information needed for workplace, PPE, and other equipment design. In the past, variance in body dimensions was typically reported as means and standard deviations for various body segments (Roebuck et al., 1975). Industrial workers, such as the agriculture, truck driver, and firefighter workforces, are also anthropometrically very different from the average civilian population (Hsiao et al, 2002).ĭiverse workforces in many occupations, as well as new roles for women in the workforce, require body-size data for designing adequate workplaces, systems, and personal protective equipment. workforce populations, and they are quite different from the average military population. However, substantial anthropometric variability exists among the various U.S. Because of the lack of anthropometric data for the general worker population, safety researchers have generally relied on data drawn from studies of military personnel, most of which was collected during the 1950s to 1970s. Inadequate fit of personal protective equipment cannot provide workers with sufficient protection from health and injury exposures.Įxisting data on the size and shape of industrial workers is limited.Inadequate length or configuration of seatbelts may lead to non-use of seatbelts, which affect post-crash survivability.The misfit of a heavy equipment cabin to a worker may produce operator blind spots that expose workers on foot to struck-by injuries.Designs that are incompatible with normal anthropometric measurements of a workforce may result in unwanted incidents.
