【OpenCV笔记】使用VS2012和OpenCV2.4.9搭建配置OpenCV开发环境

使用MS Visual C++来创建OpenCV工程,由于不同的VS版本在配置时有所差别,现特把配置过程总结下来,以方便自己和其他朋友使用. 1.软件准备 安装Visual Studio2012和OpenCV2.4.9 这里就不再对软件的安装和环境变量的设置进行说明了,其他类似的文章的设置都大抵相似,本文重点介绍一下VS2012环境的配置. 2.配置VS2012环境 (1)新建工程 你可以创建简单的控制台应用或者拥有图形用户界面的复杂应用,此处我们选择最简单常用的控制台应用. 理解解决方案(So

Shark集群搭建配置

一.Shark简介 Shark是基于Spark与Hive之上的一种SQL查询引擎,官网的架构图及性能测试图如下: 我们涉及到了2个依赖组件,1是Apache Spark, 另外一个是AMPLAB的Hive0.11. 这里注意版本的选择,一定要选择官方的推荐版本: Spark0.91 + AMPLAB Hive0.11 + Shark0.91 一定要自己编译好它们,适用于自己的集群. 二.Shark集群搭建 1. 搭建Spark集群,这个可以参照:Spark集群搭建. 2. 编译AMPLAB的Hi

OpenStack 搭建（一）

OpenStack介绍 openstack是一个云平台管理项目,我们可以使用openstack来管理我们的资源池,在这个资源池中包含了很多的子项目.openstack是有多个不同的模块组成,不同的功能有相对应得不同模块负责.openstack三大核心分别是 计算.网络.存储.通过调用不同模块的API来对外提供交互. openstack 的版本发布很快,从最初的A版到现在的N版,官方一般会每隔六个月发布一个新的版本. openstack每个服务都有对应的项目名称,不同的项目就相当于一个提供单独服务
