osgearth 编译指南
以下文档是osg和osgearth的编译过程,系统要求如下:操作系统:win7 home basic x64编译器:vs2010编译成功后会形成4个目录,分别为:1 Open Scene Graph, C:Open SceneGraph2 OpenSceneGraph,C:OpenSceneGraph3 OSG, D:OSG4 osgEarth, D:osgEarth第一个存放osg软件,用于只使用osg软件用。文件夹大小199M第二个存放osg+osgearth软件,用于使用osgearth和osg用。文件夹大小626M第三个存放osg编译过程文件,用于对osg软件升级开发用。文件夹大小3.6G第四个存放osgEarth编译过程文件,用于对osgEarth软件升级开发用。文件夹大小2.54G

本文结合DCT变换的特性,利用分形的Peano一hilbert扫描曲线,对基于DCT变换的图像编码方法进行了研究,并提出了改进方法。主要工作分为两个部分: 一是在分块DCT基础上的改进。对分块后生成的各图像块矩阵,不直接作二维DCT变换,而是先进行扫描,使之重排成一维向量,再进行一维DCT变换,这样可以减少运算量。 其次是对层次余弦变换编码部分的改进。使用层次DCT变换与零树编码相结合的方法,并在扫描编码过程中,按Peano一hilbert扫描顺序进行编码。这样不仅可以减少“块效应”,而且可以加快编码速度。-this paper the characteristics of DCT, using fractal Peano a Hilbert scanning curve, the DCT-based image coding method for the study and improvement of methods. The work is divided into two main parts : First, the DCT block on the basis of improvements. Right after block production of the image block matrix, not for direct two-dimensional DCT, but first scan, so they line up in a heavy-dimensional vector and then a peacekeeping DCT, thus reducing the amount of computation. Secondly, the level of cosine transform coding some of the improvements. The use level of DCT and zero tree coding combination of methods, coding and scanning process, according to a Hilbert Peano code scanning sequence. This will not only reduce the "blocking
