Prior research on metaballs-based modeling solely focuses on shape geometry and its processing for organic objects. This paper takes a different approach by exploring a new metaballs-based physical modeling method for digital organs that are imperative to support virtual surgery. We propose a novel hybrid physical model comprising both surface mesh and the(More)
We present a novel sketch-based 2D animation technique, which allows the user to produce 2D character animations efficiently. It consists of two parts, sketch-based skeleton-driven 2D animation production and 2D motion capture. The user inputs one image of the character and sketches the skeleton for each subsequent frame. The system deforms the character(More)
As a general approach to study interactions among small biological molecules such as genes and proteins, network analysis has aroused great interest of people from various research disciplines. However, the construction of network is usually quite sensitive to noise which is unavoidable in real data. Besides, the parameter selections for network(More)
