Multi-posed Virtual Family Models

A simulation platform to develop multi-posed models for micro-Doppler sensing is proposed. CAD model based human subject models, and hardware accelerated bio-electromagnetic modeling will be developed to understand EM interaction with human subject models. Since each organ is defined via a set of vertex coordinates, various morphing algorithm can be implemented. Consequently, the proposed models (virtual family model) can easily be opened and manipulated by open source software package OpenSim or other commercial software packages such as AMIRA, Rhino, and etc. Such flexibility in the CAD models allows for the following functions: 1) Simultaneous and realistic arbitrary positioning of the models; 2) Arbitrary placement and orientation of the human models; 3) Volumetrically accurate and tissue-depend EM properties for these models; 4) Rapid model and repositioning and placement. In house graphic processing unit accelerated finite-difference time-domain (FDTD) modeling tool will be used to perform preliminary electromagnetic simulations to understand the biometric feature of these models.
