OpenCV多核支持 [英] OpenCV Multi Core Support

问题描述

我想知道OpenCV库是否有多核支持.我正在尝试Haar级联，在具有四个核心的Raspberry 2上运行起来很慢，但是我的应用程序当前仅在单个核心上运行.

I was wondering if there is multi core support for the OpenCV library. I am experimenting with Haar cascading and it's pretty slow on my Raspberry 2 which would have four cores, but my application is currently running only on a single one.

有什么想法吗?

推荐答案

CascadedDetect具有多核支持.

使用WITH_TBB或WITH_OPENMP(或OpenCV支持的任何其他线程框架)标志重新编译OpenCV以启用它.

Recompile OpenCV with the WITH_TBB or WITH_OPENMP (or any other threading framework supported by OpenCV) flag on to enable it.
