+/**
+ * opencv 官方demo
+ * 用于测试opencv环境是否正常
+ * windows下环境配置：
+ * 1、官网下载对应版本的openvp：https://opencv.org/releases/page/2/  当前使用4.0.1版本
+ * 2、双击exe文件安装，将 安装目录下\build\java\x64\opencv_java401.dll 拷贝到\build\x64\vc14\bin\目录下
+ * 3、eclipse添加User Libraries
+ * 4、项目邮件build path，添加步骤三新增的lib
+ * 
+ * 官方demo，需要本地安装opencv，除该demo之前，均不需要安装，使用maven依赖即可，
+ * 二者之间具体有什么差别，暂时还没有时间去深入研究
