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的方法将转换后的数据填充到Mat对象中: 使用BitmapConverter.ToMat方法将Bitmap转换为Mat,并将结果存储在之前创建的Mat对象中。 csharp mat = OpenCvSharp.Extensions.BitmapConverter.ToMa...
c# opencvsharp bitmap转mat--mat转bitmap //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;...
//转为 bitmap方法一: Bitmap map=OpenCvSharp.Extensions.BitmapConverter.ToBitmap(mat);process_pictureBox.Image=map;//转为 bitmap方法二: Bitmap map=new Bitmap(mat.ToMemoryStream());process_pictureBox.Image=map;//Image img 转为Mat Bitmap bitmap=new Bitmap(img);//Image img OpenCvSharp.Ma...
