问题描述

我有一个版本的 OpenCV 2.4.10 库，它是为 Windows 上的 Intel X64 构建的.

I have a version of OpenCV 2.4.10 Library which was built for Intel X64 on Windows.

我如何知道 CV_SSE2 是否处于活动状态?我没有代码.我只有库、DLL 和头文件.

How can I know if the CV_SSE2 is active? I do not have the code. I just have the libs ,DLLs and headers.

谢谢

推荐答案

您可以使用 checkHardwareSupport 像:

#include <opencv2/opencv.hpp>
#include <iostream>

int main()
{
    cv::setUseOptimized(true); // Turn on optimization (if it was disabled)

    // Get other build information
    //std::cout << cv::getBuildInformation(); 

    // Check SSE2 support
    std::cout << cv::checkHardwareSupport(CV_CPU_SSE2);

    return 0;
}
