在C#中使用OpenCvSharp库将Image对象转换为Mat对象是一个常见的操作。以下是详细的步骤和代码示例,用于实现这一转换: 1. 导入OpenCvSharp库 首先,确保你的项目中已经安装了OpenCvSharp库。你可以通过NuGet包管理器来安装它。在你的项目目录中打开“包管理器控制台”,并运行以下命令来安装OpenCvSharp: shell Install-Packa...
if(File.Exists("image.data")) { FileStorage fileStorage = new FileStorage("image.data", FileStorage.Modes.Read); Mat resultMat = fileStorage["image"].ToMat(); pictureBox2.Image = OpenCvSharp.Extensions.BitmapConverter.ToBitmap(resultMat); //Mat转Bitmap } } private void button4_Click(objec...
OpenCvSharp.Mat mat = OpenCvSharp.Extensions.BitmapConverter.ToMat(bitmap);//用 //bitmap转换为mat C#中Bitmap 与 Image 之间的转换 Image img = pictureBox1.Image; Bitmap map = new Bitmap(img); //而Bitmap直接可以赋值 给 Image 对象 Image img = Bitmap;...

OpenCvSharp.Mat mat=OpenCvSharp.Extensions.BitmapConverter.ToMat(bitmap);//用 //bitmap转换为mat C#中Bitmap 与 Image 之间的转换Image img=pictureBox1.Image;Bitmap map=new Bitmap(img);//而Bitmap直接可以赋值 给 Image 对象 Image img=Bitmap; ...
Mat image; StringBuilder sb = new StringBuilder(); private void Form1_Load(object sender, EventArgs e) { image = new Mat(3, 2, MatType.CV_8UC3); Cv2.Randu(image, Scalar.All(0d), Scalar.All(255d)); pictureBox1.Image = new Bitmap(image.ToMemoryStream()); ...
void ShowImg(Mat mat) { pictureBox2.Image = OpenCvSharp.Extensions.BitmapConverter.ToBitmap(mat); } private void tBarThreshold_Scroll(object sender, EventArgs e) { if (tBarMaxval.Value < tBarThresh.Value) { tBarThresh.Value = tBarMaxval.Value; ...
pictBox_result.Image=BitmapConverter.ToBitmap(mat_bg); } 效果如图: 四、操作视频帧图片,实现替换绿幕 和图片的区别,就是需要先逐帧获取 视频/摄像机 的图片,然后按上述操作进行 直接附上完整Demo(已经将两个函数改为指针操作,大家可以先试试原来的At操作,可以明显看到视频是慢速播放) ...
