OpenCV学习笔记-\doc\tutorials\imgproc\gausian_median_blur_bilateral_filter

文档中没有修改作者的代码，作者程序的意思是要逐个显示四个滤波器的处理结果，我将代码修改了一下，一并显示结果，其中MAX_KERNEL_LENGTH取为31，这次不用lena了，用林采缇同学来提神。显示结果如下：

代码如下：

#include "opencv2/imgproc/imgproc.hpp"
#include "opencv2/highgui/highgui.hpp"

using namespace std;
using namespace cv;

/// Global Variables
int MAX_KERNEL_LENGTH = 31;

Mat src; 
Mat dst1,dst2,dst3,dst4;

int main( int argc, char** argv )
{
  // Create Windows
  namedWindow("Source Image");
	namedWindow("Homogeneous Blur");
  namedWindow("Gaussian Blur");
  namedWindow("Median Blur");
  namedWindow("Bilateral Blur");
  
  // Load the source image
  src = imread( "azhai.jpg", 1 );
  
  // Show Original Image
  imshow("Source Image",src);

  // Copies for output
  dst1 = src.clone();
  dst2 = src.clone();
  dst3 = src.clone();
  dst4 = src.clone();

  // Applying Homogeneous blur
  blur( src, dst1, Size(MAX_KERNEL_LENGTH,MAX_KERNEL_LENGTH), Point(-1,-1) );
  imshow("Homogeneous Blur",dst1);

  // Applying Gaussian blur
  GaussianBlur( src, dst2, Size(MAX_KERNEL_LENGTH,MAX_KERNEL_LENGTH), 0, 0 );
  imshow("Gaussian Blur",dst2);
  
  // Applying Median blur
  medianBlur ( src, dst3, MAX_KERNEL_LENGTH);
  imshow("Median Blur",dst3);

  // Applying Bilateral Filter
  bilateralFilter ( src, dst4, MAX_KERNEL_LENGTH, MAX_KERNEL_LENGTH*2, MAX_KERNEL_LENGTH/2 );
  imshow("Bilateral Blur",dst4);
  
  waitKey(0);
  return 0;
 }
