  • 顶点倒塌(Vertex Collapse)算法中

    顶点倒塌(Vertex Collapse)算法中,一开始图中的N个顶点看作N个孤立的超顶点(Super Vertex),算法运行中,有边连通的超顶点相继合并,直到形成最后的整个连通分量。每个顶点属于且仅属于一个超顶点,超顶点中标号最小者称为该超顶点的根。

  • 实验8 继承与多态 8.1 实验目的 (1) 理解类的继承

    实验8 继承与多态 8.1 实验目的 (1) 理解类的继承,掌握变量隐藏、方法覆盖的概念。 (2)理解引用类型的变量的赋值转换原则。 (3)理解多态概念,掌握方法的匹配调用原则; (4)理解抽象类与接口的使用; (5)理解this和Super的含义及使用。 (6)理解访问控制符的使用 8.2 知识要点 8.2.1 继承的概念 通过类的继承,祖先类的所有成员均将成为子类拥有的“财富”。但是能否通过子类对象直接访问这些成员则取决于访问权限设置。Object类是所有类的祖先。 8.2.2 构造方法与继承关系 构造方法不存在继承关系,子类中是如何给父类继承的属性赋初值呢? 子类通过调用父类的构造方法给父类的属性赋值,在子类的构造方法的第1行可以通过Super去调用父类的构造方法,如果没有Super调用,则默认调用父类的无参构造方法。所以,在父类中编写构造方法通常均要提供无参构造方法。 8.2.3 对象引用变量赋值原则 可以将子类的对象引用赋值给父类引用变量,由于父类能操作访问属性和方法的子类已全部继承。但将父类引用变量的值赋给子类引用变量就受到限制,必须进行强制转换,编译总是认可强制转换,但运行程序时如果不能正确转换就会报错。

  • 第四次作业 1、 创建一个Animal(动物)类

    第四次作业 1、 创建一个Animal(动物)类,让Horse(马),Dog(狗),Cat(猫)等动物继承Animal类。在Animal类中定义一些方法,让其子类重写这些方法,编写一个运行时多态的程序。 创建一个Animal类型的数组,在其中填充不同子类,然后调用自己的父类中的方法,看看会有什么情况发生。 2、 修改练习3.3,使Animal成为一个接口。 3、 在面向对象的绘图应用应用程序中,可以绘制圆形、矩形、直线等很多其他的图形对象。这些对象都具有相同的特定状态(例如位置、方向、线条颜色和填充颜色)和行为(例如移动、旋转、改变大小和绘制)。一些状态和行为对所有图形是相同的,例如位置、填充颜色和移动。另一些状态和行为需要不同的实现,例如改变大小和绘制。所有GraphicObject都知道如何绘制自己和如何改变自己的大小;只不过完成的操作不同。 请设计GraphicObject类和所有子类的方法,其中用到抽象类和抽象方法、抽象方法、方法的重写和多态、Super关键字等概念。并测试其正确性。他们之间的关系用类图表示。 4 用策略模式实现网上书城不同类型的图书折扣策略,计算出每种类型的图书的价格。并编程测试之。

  • 基于多尺度字典的图像超分辨率重建

    Reconstruction- and example-based Super-resolution (SR) methods are promising for restoring a high-resolution (HR) image from low-resolution (LR) image(s). Under large magnification, reconstruction-based methods usually fail to hallucinate visual details while example-based methods sometimes introduce unexpected details. Given a generic LR image, to reconstruct a photo-realistic SR image and to suppress artifacts in the reconstructed SR image, we introduce a multi-scale dictionary to a novel SR method that simultaneously integrates local and non-local priors. The local prior suppresses artifacts by using steering kernel regression to predict the target pixel from a small local area. The non-local prior enriches visual details by taking a weighted average of a large neighborhood as an estimate of the target pixel. Essentially, these two priors are complementary to each other. Experimental results demonstrate that the proposed method can produce high quality SR recovery both quantitatively and perceptually.

  • From GSM to LTE-Advanced Pro and 5G

    Wireless technologies like GSM, UMTS, LTE, Wireless LAN and Bluetooth have revolutionized the way we communicate by making services like telephony and Internet access available anytime and from almost anywhere. Today, a great variety of technical publications offer background information about these technologies but they all fall short in one way or another. Books covering these technologies usually describe only one of the systems in detail and are generally too complex as a first introduction. The Internet is also a good source, but the articles one finds are usually too short and Super- ficial or only deal with a specific mechanism of one of the systems. For this reason, it was difficult for me to recommend a single publication to students in my telecommunication classes, which I have been teaching in addition to my work in the wireless telecommunication industry. This book aims to change this.
