在OpenCvSharp中,Mat是用于存储图像的主要数据结构。你需要创建一个Mat对象来存储转换后的图像数据。 csharp Mat mat = new Mat(); 将Bitmap的像素数据转换为Mat可以接受的格式: 在OpenCvSharp中,你可以使用BitmapConverter.ToMat方法直接将Bitmap转换为Mat。这个方法会自动处理像素数据的转换。 使用OpenCvSharp的方...
//Mat mat = OpenCvSharp.Extensions.BitmapConverter.ToMat(bitmap);//bitmap转mat//mat = mat.CvtColor(ColorConversionCodes.GRAY2RGB);//转彩色图像//mat = DrawCross(mat, new System.Drawing.Point(640, 512), 0.0, 1000, Scalar.Red, 2);Bitmap bitmap; bitmap= OpenCvSharp.Extensions.BitmapConve...
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;...
