c++ - 错误 : namespace "cv::cuda" has no member "resize"

Question

我已经使用 WITH_CUDA=on 成功构建了 opencv。但我仍然面临这个错误error: namespace "cv::cuda"has no member "resize"。奇怪的是，IDE 提示我在该命名空间中有一个调整大小的函数，但它在编译时失败了。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>解决问题。
