Question

我已经用WITH_CUDA=on成功构建了opencv。但我仍然遇到此错误error: namespace "cv::cuda" has no member "resize"。 IDE建议我在该命名空间中有一个resize函数，但是编译失败，这很奇怪。有谁知道如何解决这个问题？

#include "opencv2/highgui.hpp"
#include "opencv2/imgproc.hpp"
#include "opencv2/video/background_segm.hpp"
#include "opencv2/video/tracking.hpp"
#include "opencv2/cudev/ptr2d/gpumat.hpp"
#include "opencv2/cudev/ptr2d/resize.hpp"
#include "newfile.h"

using namespace cv;
using namespace std;

int test() {
    cv::Mat LoadedImage;
    cv::cuda::GpuMat Im;

    LoadedImage = imread("in.jpg", IMREAD_COLOR);
    Im.upload(LoadedImage);
    cv::cuda::resize(LoadedImage, LoadedImage, cv::Size(), 0.5, 0.5, cv::INTER_NEAREST);

    imwrite("Step4a.JPG", LoadedImage);
    return 0;
}

正如@john指出的那样。我应该#include <opencv2/cudawarping.hpp>来解决问题。

错误：名称空间“ cv :: cuda”没有成员“调整大小”
