Description: classification_tutorial
讲述流分类的算法。-The process of categorizing packets into “flows” in an Internet router is called packet
classification. All packets belonging to the same flow obey a pre-defined rule and are processed in
a similar manner by the router. For example, all packets with the same source and destination IP
addresses may be defined to form a flow. Packet classification is needed for non “best-effort”
services, such as firewalls and quality of service services that require the capability to distinguish
and isolate traffic in different flows for suitable processing. In general, packet classification on
multiple fields is a difficult problem. Hence, researchers have proposed a variety of algorithms
which, broadly speaking, can be categorized as “basic search algorithms,” geometric algorithms,
heuristic algorithms, or hardware-specific search algorithms. In this tutorial we describe
algorithms that are representative of each category, and discuss which type of algorithm might be
suitable for different

Description: 求解过程中，由于几何模型发生变化而导致区域网格改变时会出现几何结构的连续性问题。本章中，我们举两个例子——流道中由于不同尺寸孔板引起额外压力损失问题是稳态几何连续性的一个例子。从概念来看，这个问题与第5章贝纳尔问题中通过Rayleigh数进行的变量连续性没什么不同。第二个例子是液体中悬浮的乳胶颗粒的干膜。在这个问题中，考虑了两个移动前缘；一个通过坐标变换，另一个通过光滑界面模型。该技术对于之前模拟该问题采用的移动弱项方法有所改进。-Solving process, due to geometry changes and the continuity of the geometric structure of the regional grid changes. In this chapter, we give two examples- the flow channel due to the different size orifice caused by the additional pressure loss is an example of the steady-state geometric continuity. Variable continuity standpoint, this issue in Chapter 5 Bernal Rayleigh number is no different. The second example is a dry film of the latex particles suspended in the liquid. In this problem, consider the two move the leading edge a coordinate transformation, and the other by the smooth interface model. The technology used before to simulate the mobile weaknesses improvements.

Description: 光流是一种简单实用的图像运动的表达方式[1] ，通常定义为一个图像序列中的图像亮度模式的表观运动，即空间物体表面上的点的运动速度在视觉传感器的成像平面上的表达。这种定义认为光流只表示一种几何变化。1998年Negahdaripour将光流重新定义为动态图像的几何变化和辐射度变化的全面表示[2] 。光流的研究是利用图像序列中的像素强度数据的时域变化和相关性来确定各自像素位置的“运动”，即研究图像灰度在时间上的变化与景象中物体结构及其运动的关系。一般情况下，光流由相机运动、场景中目标运动或两者的共同运动产生的相对运动引起的。光流计算方法大致可分为三类：基于匹配的方法、频域的方法和梯度的方法。-Optical flow expression is a simple and practical image motion [1], is usually defined as the apparent motion of an image sequence image brightness mode, ie velocity of points on the surface of the object on the imaging plane space vision sensor expression. This definition is considered only optical flow shows a geometric variation. 1998 Negahdaripour will redefine optical flow motion picture geometry changes and radiometric variations comprehensive representation [2]. Optical flow study is the use of temporal changes in a sequence of images pixel intensity data and to determine the relevance of each pixel position of " movement" , that is, the relationship between research grayscale image at the time of the scene changes in the structure and motion of objects . In general, the optical flow by the camera motion, relative motion common target movement or motion scenes both produce caused. Optical flow calculation method can be broadly divided into three categories: matching meth

Description: This study presents a geometric model for
segmentation of ultrasound images. A partial differential
equation based flow is designed in order to achieve a
maximum likelihood segmentation of the target in the
scene. The flow is derived as the steepest descent of an
energy functional taking into account the density
probability distribution of the gray levels of the image as
well as smoothness constraints. To model gray level
behavior of ultrasound images the classic Rayleigh
probability distribution is considered. The steady state of
the flow presents a maximum likelihood

The program is only suitable for the numerical simulation of simple two-dimensional rectangular boundary, compressible flow, unsteady and Euler equations. After coordinate transformation, it can be applied to more calculations of other geometric shapes.)
