基于运动捕获数据的三维角色动画设计

本文研究了怎样把现有的人体运动数据重新定向到新的动画角色对象上,并实现了一个原型系统——盼盼三维角色动画系统。通过这种方法,用户只需要从动画库中选择所需的人体运动,便可方便地控制任意三维动画角色的运动和变形,从而重用现存的人体运动数据去控制新的角色,创作出一些夸张的动画效果。

Reimagining the Wheel: Using Circular Calendars for Planning in Law School Libraries

This essay proposes using a wheel or circular calendar to identify and document the events and projects of an academic law school year, both in and out of the classroom. The idea of harnessing the natural cyclical process of law school for library planning comes from concept mapping, which can conceptualize an issue by using a variety of mapping strategies to organize and show the relationships between pieces of information and a central concept. Using a wheel graphic to visualize a process can facilitate project management and aid in teaching legal research strategy.     

A''da''m-自补有向循环图

A'da'm自补有向循环图是循环图中很独特的一类,有很好应用前景,特别在网络时代的今天,A'da'm自补有向循环图更具它独特的魅力。但是,A'da'm自补有向循环图一般结构很难给出,本文给出了三类自补有向循环图。     

论反事实思维和情绪的关系

反事实思维是个体对过去事件加以心理否定并构建出一种假设可能的思维活动。目前关于反事实思维的研究已经逐渐引起心理学界的广泛关注。不同的反事实思维定向中,个体所采取的关注点不同,随之带来的情绪也是不同的。

基于四轴运动控制教学平台的多元实践体系改革

针对高等教育教学中重理论、轻实践,未注重学生创新能力以及综合能力培养等问题,设计了一款可模拟实际工业检测分类装置的运动控制教学平台。该平台不但能够很好地模拟实际的工业场景,实现基本的运动控制功能,还具有很好的开放性和可扩展性。运动控制教学平台既可用于随堂常规实践,也可用于注重学生创新能力及综合思维能力培养的课程设计和毕业设计,形成多元化的实践教学体系。在加深学生对所学知识理解的基础上,充分锻炼他们的创新能力、解决问题的能力以及工程实践能力,培养真正适应于社会的工程应用型人才。     

Classroom

In this section of Resonance, we invite readers to pose questions likely to be raised in a classroom situation. We may suggest strategies for dealing with them, or invite responses, or both. “Classroom” is equally a forum for raising broader issues and sharing personal experiences and viewpoints on matters related to teaching and learning science. This project was done as part of the Research Education Advancement Programme held over weekends at the Bangalore Association for Science Education, Jawaharlal Nehru Planetarium, Bangalore.     

一种有效的基于运动矢量场的压缩域运动对象分割算法

In this paper an efficient compressed domain moving object segmentation algorithm is proposed, in which the motion vector (MV) field parsed from the compressed video is the only cue used for moving object segmentation. First the MV field is temporally and spatially normalized, and then accumulated by an iterative backward projection to enhance salient motions and alleviate noisy MVs. The accumulated MV field is then segmented into motion-homogenous regions using a modified statistical region growing approach. Finally, moving object regions are extracted in turn based on minimization of the joint prediction error using the estimated motion models of two region sets containing the candidate object region and other remaining regions, respectively. Experimental results on several H.264 compressed video sequences demonstrate good segmentation performance.
