在opencv c ++中将高斯模糊/滤镜应用于图像

Question

我使用openCV中的高斯函数使我的图像模糊/滤镜，并在模糊应用之前和之后检索图像像素的值。

问题是没有模糊和模糊的图像之间的像素值没有差异，但是高斯模糊之后的图像显示实际上是模糊的并且核矩阵的大小是3 * 3。如果有人能解决这个问题，肯定会感激，提前谢谢，这是我的代码。

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

using namespace cv;
using namespace std;


int main()
{
  Mat image = imread("C:/santhu/bitmap.bmp");
  int rows=image.rows;
  int cols=image.cols;

  if (image.empty()) 
    {
      cout << "Cannot load image!" << endl;
      return -1;
    }

  cout<<"the output for matrix of pixels";

  //code to access pixel values of an image
  cout<<"\nbefore blur";
  for (int i = 0; i <rows; i++)
    {
      Vec3b *ptr = image.ptr<Vec3b>(i);

      for (int j = 0; j < cols; j++)
        {   
      Vec3b pixel = ptr[j];
      //cout<<pixel<<"\t";
        }
      cout<<"\n";
    }

  imshow("Image", image);//displaying image
  waitKey(0);

  Mat image1=image.clone();//cloning image

  GaussianBlur( image, image1, Size( 7, 7), 0, 0 );//applying Gaussian filter 


  cout<<"\nafter blur";

  //code to access pixel values of an image
  for (int i = 0; i < rows; i++)
    {
      Vec3b *ptr = image1.ptr<Vec3b>(i);

      for (int j = 0; j < cols; j++)
        {   
      Vec3b pixel = ptr[j];
      //cout<<pixel<<"\t";
        }
      cout<<"\n";
    }


  imshow("image1:",image1);//displaying image1
  waitKey(0);
}
