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.我正在试验 Haar 级联，它在具有四个内核的 Raspberry 2 上非常慢，但我的应用程序目前仅在一个内核上运行.

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.
