image - 将图像保存在完整路径中

Question

我正在使用OpenCV库和Visual Studio2013。我只想将结果图像保存在完整路径中。相同的路径没关系，但是c:\\...不起作用。
我尝试同时使用正向\和反向/，结果看起来相同。
这是代码:

#include<iostream>
#include<opencv2/imgproc/imgproc.hpp>
#include<opencv2/highgui/highgui.hpp>

using namespace std;
using namespace cv;

int main()
{

Mat src, dst;
float sum;

/// Load an image
src = imread("lena.jpg", CV_LOAD_IMAGE_GRAYSCALE);

if (!src.data)
{
    return -1;
}

// define the kernel
float Kernel[3][3] = {
    { 1 / 9.0, 1 / 9.0, 1 / 9.0 },
    { 1 / 9.0, 1 / 9.0, 1 / 9.0 },
    { 1 / 9.0, 1 / 9.0, 1 / 9.0 }
};
dst = src.clone();
for (int y = 0; y < src.rows; y++)
for (int x = 0; x < src.cols; x++)
    dst.at<uchar>(y, x) = 0.0;
//convolution operation
for (int y = 1; y < src.rows - 1; y++){
    for (int x = 1; x < src.cols - 1; x++){
        sum = 0.0;
        for (int k = -1; k <= 1; k++){
            for (int j = -1; j <= 1; j++){
                sum = sum + Kernel[j + 1][k + 1] * src.at<uchar>(y - j, x - k);
            }
        }
        dst.at<uchar>(y, x) = sum;
    }
}

namedWindow("final");
imshow("final", dst);

namedWindow("initial");
imshow("initial", src);
vector<int> compression_params; //vector that stores the compression parameters of the image

compression_params.push_back(CV_IMWRITE_JPEG_QUALITY); //specify the compression technique

compression_params.push_back(100); //specify the compression quality

bool bSuccess = imwrite("filtre.jpg", dst, compression_params);//ok
    bool bSucccess = imwrite("D:/trunk/jpwl/Release/nouveau_dossier/filtre.jpg", dst, compression_params);// not ok
    bool bSuccces = imwrite("D:\trunk\jpwl\Release\nouveau_dossier\filtre.jpg", dst, compression_params);// not ok

waitKey();


return 0;
}

Answer 1

使用:
“D:\ trunk \ jpwl \ Release \ nouveau_dossier \ filtre.jpg”(带有两个反斜杠，Stackoverflow也显示一个反斜杠)

要么

@“D:/trunk/jpwl/Release/nouveau_dossier/filtre.jpg”
代替。单个\是ESC字符。
