Windows下VS17(版本通用)+Dlib19.17配置过程

首先需要有Cmake软件和Dlib19.17(也可以自己选其他版本，过程大致一样)

如果不想自己编译的话可以看我的这篇博客，里面有已经编译好的可以直接下载，如果只是为了配置建议下载这个，更快更简便

（仅限于VS17 x64 Release+Dlib19.17）

https://blog.youkuaiyun.com/wilsonass/article/details/90581852

 

首先去下载Dlib文件

http://dlib.net/

解压出来Dlib-19.17

打开Cmake

 

修改CMAKE_INSTALL_PREFIX的路径，为dlib-19.17/install

先点击Configure等待完成然后点击Generate

中间会出来一个界面，选择自己相对应的版本

完成后点击Open Project

 

在打开的VS工程中右键点击ALL_BUILD进行生成，然后等待完成。

右键点击INSTALL进行生成，然后等待完成。

 

然后在自己的VS项目中进行配置 include和lib

 

写入输入的附加依赖项

dlib19.17.0_release_64bit_msvc1916.lib;

写入测试代码

其中的string img_path = "001.jpg";是当前目录下的图片，通过把图片重命名移动到项目的当前目录下可进行测试

当前目录为：右键项目，选择在资源管理器中打开文件夹

 

#include <dlib/gui_widgets.h>
#include <dlib/image_io.h>
#include <dlib/image_transforms.h>
#include <fstream>


using namespace std;
using namespace dlib;

//  ----------------------------------------------------------------------------

int main(int argc, char** argv)
{
	try
	{

		// 声明图像
		array2d<rgb_pixel> img;

		string img_path = "001.jpg";
		load_image(img, img_path);

		// 高斯模糊
		array2d<unsigned char> blurred_img;
		gaussian_blur(img, blurred_img);

		// sobel边缘检测
		array2d<short> horz_gradient, vert_gradient;
		array2d<unsigned char> edge_image;
		sobel_edge_detector(blurred_img, horz_gradient, vert_gradient);

		//非极大边缘抑制
		suppress_non_maximum_edges(horz_gradient, vert_gradient, edge_image);

		// 显示结果
		image_window my_window(edge_image, "Normal Edge Image");

		// We can also easily display the edge_image as a heatmap or using the jet color
		// scheme like so.
		image_window win_hot(heatmap(edge_image));
		image_window win_jet(jet(edge_image));

		// also make a window to display the original image
		image_window my_window2(img, "Original Image");

		// Sometimes you want to get input from the user about which pixels are important
		// for some task.  You can do this easily by trapping user clicks as shown below.
		// This loop executes every time the user double clicks on some image pixel and it
		// will terminate once the user closes the window.
		point p;
		while (my_window.get_next_double_click(p))
		{
			cout << "User double clicked on pixel:         " << p << endl;
			cout << "edge pixel value at this location is: " << (int)edge_image[p.y()][p.x()] << endl;
		}

		// wait until the user closes the windows before we let the program 
		// terminate.
		win_hot.wait_until_closed();
		my_window2.wait_until_closed();


		// Finally, note that you can access the elements of an image using the normal [row][column]
		// operator like so:
		cout << horz_gradient[0][3] << endl;
		cout << "number of rows in image:    " << horz_gradient.nr() << endl;
		cout << "number of columns in image: " << horz_gradient.nc() << endl;
	}
	catch (exception& e)
	{
		cout << "exception thrown: " << e.what() << endl;
	}
}
