标题[问题] SSE与opencv2.1的问题
时间Thu Dec 2 11:31:46 2010
各位大大, 想请教目前opencv2.1和sse的关系
小弟在一篇文章上提到
OpenCV was released on 6th May. This time the development team did not
release pre-built library for MinGW. They only released that for MSVC . There
was only one pre-built release library uploaded by other user but SSEs were
disabled.
然後小弟在网路上下载这个档案OpenCV-2.1.0-win32-vs2008.exe
的确像opencv1.0一样,直接安装就可以用了
但是执行程式时,效能却没有提昇
所以想说,应该是这个版本的程式库并没有enable sse library.
然後目前使用cmake和opencv2.1.0去重新compile
但是却没有发现enable sse的选项
所以想请教各位大大,如何enable Opencv里面的sse指令集呢
谢谢大大指教
