We propose an integrated facial dynamics model addressing the animation of 3D humanoid faces in real time. The computational model mimics facial motion by reproducing the layered anatomical structure of a human head including the bony structure, overlapping facial muscles and the skin. The model is flexible enough to animate face meshes of various shape, connectivity, and scale. Different from ...

On account of having real-time behavior and being easy to implement, spring meshes have been used for modeling deformable objects. Determining spring stiffness parameters for simulation of soft objects with high accuracy still remains a challenge. Allen Van Gelder derived an approximate formula for determining spring stiffness parameters based on strain analysis. Even though the experimental re...

We introduce an approach for converting pixel art into high-quality vector images. While much progress has been made on automatic conversion, there is inherent ambiguity in art, which can lead to a mismatch with the artist's original intent. Further, room incorporating aesthetic preferences during conversion. In consequence, this work introduces interactive framework enable users guide conversi...

the incremental sheet metal forming (ismf) process is a new and flexible method that is well suited for small batch production or prototyping. this paper studies the use of the finite element method in the incremental forming process of aa1050 sheets to investigate the influence of tool diameter, vertical step size, and friction coefficient on forming force, spring-back, and thickness distribut...

We have developed a novel control mechanism that deploys a large number of inexpensive robots as a distributed remote sensing array, called a Distributed Robotic Macrosensor (DRM). A simple virtual spring mesh abstraction is used to provide fully distributed control that is both flexible and fault-tolerant. We describe and evaluate several algorithms for virtual spring mesh–based control and pr...

Field crop yield prediction is crucial to grain storage, agricultural field management, and national agricultural decision-making. Currently, crop models are widely used for crop yield prediction. However, they are hampered by the uncertainty or similarity of input parameters when extrapolated to field scale. Data assimilation methods that combine crop models and remote sensing are the most eff...
