In view of animated human computer interfaces, this paper proposes a 3D head mesh modeling and expressive articulatory animation system. The appearance mesh model is first reconstructed from multi-view visible images using inter-regional cooperative optimization and depth super-resolution, and the universal internal articulatory mesh is then integrated with the reconstructed appearance mesh by interpolation...
A 3D realistic tongue system is proposed. Firstly, the muscle geometry and fiber arrangement are specified after a tongue mesh model is constructed from medical data. Secondly, with the target of the efficiency and realism of animation, the tongue tissues, including tongue muscles, are described by combining a fast parametric model and a precise anatomical model to simulate the active and passive...
We built a 3D anatomically and biomechanically accurate physiological tongue model for use in visual speech synthesis. For the anatomical modeling part, the tongue and its muscles are constructed based on accurate medical data. Due to their complexity, muscles geometry and fiber arrangement are specified by a proposed interactive muscle marking method. For the biomechanical modeling part, a nonlinear,...
Although citizen science projects can engage a very large number of volunteers to collect volumes of data, they are susceptible to issues with data quality. Our experience with eBird, which is a broad-scale citizen science project to collect bird observations, has shown that a massive effort by volunteer experts is needed to screen data, identify outliers and flag them in the database. The increasing...
Citizen scientists, who are volunteers from the community that participate as field assistants in scientific studies, enable research to be performed at much larger spatial and temporal scales than trained scientists can cover. Species distribution modeling, which involves understanding species-habitat relationships, is a research area that can benefit greatly from citizen science. The eBird project...
In stochastic traffic assignment, if the total perceived travel cost of all users is used as the system performance index, the stochastic system optimum (SSO) assignment is then to minimize the total perceived travel cost. In this study, we investigate the existence of nonnegative uniform link tolls and the efficiency loss of congestion pricing of multiclass stochastic user equilibrium (SUE) traffic...
Almost existence literature about the inefficiency in traffic assignment assumes user is entirely selfishness. In this paper, assumed the users are not entirely selfishness, they are partially altruistic. The user’s perceived cost assumed to be a linear combination of selfish component and altruistic component. A variational inequality model is present to formulate the uniformly altruistic route choice...
