Amethod of shadowpuppet figure modeling and animation

Xiao-fang HUANG,Shou-qian SUN,Ke-jun ZHANG,Tian-ning XU,Jian-feng WU,Bin ZHU

Frontiers of Information Technology & Electronic Engineering 2015, Volume 16, Issue 5,   Pages 367-379 doi: 10.1631/FITEE.1400351

Abstract: To promote the development of the intangible cultural heritage of the world, shadow play, many studies have focused on shadow puppet modeling and interaction. Most of the shadow puppet figures are still imaginary, spread by ancients, or carved and painted by shadow puppet artists, without consideration of real dimensions or the appearance of human bodies. This study proposes an algorithm to transform 3D human models to 2D puppet figures for shadow puppets, including automatic location of feature points, automatic segmentation of 3D models, automatic extraction of 2D contours, automatic clothes matching, and animation. Experiment proves that more realistic and attractive figures and animations of the shadow puppet can be generated in real time with this algorithm.

Developments in semiconductor thermoelectric materials

Laifeng LI, Zhen CHEN, Min ZHOU, Rongjin HUANG

Frontiers in Energy 2011, Volume 5, Issue 2,   Pages 125-136 doi: 10.1007/s11708-011-0150-1

Abstract: A surge in interest in developing alternative renewable energy technologies has been observed in recent years. In particular, thermoelectrics has drawn attention because thermoelectric effects enable direct conversion between thermal and electrical energy, and provide power generation and refrigeration alternatives. During the past decade, the performance of thermoelectric materials has been considerably improved; however, many challenges continue to exist. Developing thermoelectric materials with superior performance means tailoring interconnected thermoelectric physical parameters-electrical conductivities, Seebeck coefficients, and thermal conductivities for a crystalline system. The objectives of this paper are to introduce the recent developments in semiconductor thermoelectric materials, and briefly summarize the applications of such materials.
