Description: 多媒体设备软硬件联合设计平台开发。pdf版。-This book is the outcome of a recent international collaborative research project
aiming at developing both the hardware and software of a platform based SoC
(System-on-Chip) architecture for embedded multimedia systems. Since its incep-
tion a decade ago, SoC has captured the attentions of application specifi c integrated
circuit (ASIC) design houses, computer aided design (CAD) companies, and embed-
ded system developers. In particular, the immense popularity of killer multimedia
gadgets such as iPod, and iPhone has fueled unprecedented interests in developing
new generation multimedia SoC systems.

Description: 采用Creator 和Vega 平台以及Simulink仿真开发工具对空面导弹的飞行视景仿真技术进行了研究。提出了一种空面导弹飞行视景仿真系统的体系构架，利用获取的DED真实地形数据，通过Creator建立大地形三维模型；借助VC/MFC开发平台，实现了Simulink数字仿真系统与视景仿真的通信；在Vega中实现视景仿真系统的软件开发调试。仿真结果表明，该系统能够为空面武器系统研制阶段的参数优化和效能评估提供有效的验证平台。-Creator and Vega used Simulink simulation platform and development tools, face-to-air missile flight visual simulation technology was studied. A blank surface missile flight visual simulation system architecture, use the DED for real terrain data, terrain through the Creator to establish a large three-dimensional model with VC/MFC development platform, digital simulation implemented Simulink and Visual Simulation System communications in Vega to achieve visual simulation system software development and debugging. Simulation results show that the system can be empty surface weapon system development phase of the parameter optimization and performance evaluation of an effective verification platform.

Description: 水平集是跟踪轮廓和表面运动的一种数字化方法。不直接对轮廓进行操作，而是将轮廓
设置成一个高维函数的零水平集，这个高维函数叫做水平集函数：Ψ(X,t) 。然后水平集函数
运动成为一个微分方程。在任何时候，通过从输出中提取零水平集 (( ), ) { ( , ) 0} Xt Xt Γ =Ψ = 来
得到运动的轮廓。使用水平集的主要优点是可以对任何复杂的结构进行模式化和拓扑变换，
比如暗中操作融合和分离。-The paradigm of the level
set is that it is a numeri-cal method for tracking the
evolution of contours and
surfaces. Instead of ma-nipulating the contour di-rectly, the contour is embed-ded as the zero level set of a higher dimensional function called the level-set function,ψ(X,t). The level-set func-tion is then evolved under the control of a differential
equation. At any time, the
evolving contour can be ob-tained by extracting the zero
level-set Γ((X),t) ={ψ(X,t) =0}from the output. The main advantages of using level sets is that arbitrarily complex shapes can be modeled and topological changes such as merging and splitting are handled implicitly.
