emgucv中mat的含义是什么？ [英] What is meaning of mat in emgucv?

问题描述

我想通过使用emgucv库来显示图片的直方图，但我对Mat指令有问题，程序给出了一条消息Mat没有找到......如何解决？我可以用什么代替呢？



我尝试过的事情：

使用Emgu.CV; 
使用Emgu.CV.Structure; 
 
命名空间直方图
 {
公共部分类Form1：表格
 {
图像< Bgr，字节> IMGB; 
图像<灰色，字节> imgG; 
 public Form1（）
 {
 InitializeComponent（）; 
} 
< pre> private void button1_Click（object sender，EventArgs e）
 {
 OpenFileDialog ofd = new OpenFileDialog（）; 
 if（ofd.ShowDialog（）== DialogResult.OK）
 {
 imgB = new Image< Bgr，byte>（ofd .FileName）; 
 imageBox1.Image = imgB; 
 imageBox1.FunctionalMode = Emgu.CV.UI.ImageBox.FunctionalModeOption.Minimum; 
} 
} 
 
 private void button2_Click（object sender，EventArgs e）
 {
 imgG = imgB.Convert< Gray，byte>（）; 
 panAndZoomPictureBox1.Image = imgG.Bitmap; 
} 
 
 private void button3_Click（object sender，EventArgs e）
 {
 DenseHistogram hist = new DenseHistogram（256，new RangeF（0,255））; 
 hist.Calculate（new Image< Gray，byte> [] {imgB [0]}，false，null）; 
 Mat m = new Mat（）; 
 hist.Copy（m）; 
 
 histogramBox1.AddHistogram（Blue，Color.Blue，m）; 
} 
}

I want to display a histogram of the picture by using emgucv library but I have a problem with the instruction "Mat", the program gives a message that the 'Mat' do not found...how solve that? and by what I can replace it?

What I have tried:

using Emgu.CV;
using Emgu.CV.Structure;

namespace histogram
{
    public partial class Form1 : Form
    {
        Image<Bgr, byte> imgB;
        Image<Gray, byte> imgG;
        public Form1()
        {
            InitializeComponent();
        }
<pre>private void button1_Click(object sender, EventArgs e)
        {
            OpenFileDialog ofd = new OpenFileDialog();
            if(ofd.ShowDialog()==DialogResult.OK)
            {
                imgB = new Image<Bgr, byte>(ofd .FileName );
                imageBox1.Image = imgB;
                imageBox1.FunctionalMode = Emgu.CV.UI.ImageBox.FunctionalModeOption.Minimum;
            }
        }

        private void button2_Click(object sender, EventArgs e)
        {
            imgG = imgB.Convert<Gray, byte>();
            panAndZoomPictureBox1.Image = imgG.Bitmap;
        }

        private void button3_Click(object sender, EventArgs e)
        {
            DenseHistogram hist = new DenseHistogram(256, new RangeF(0, 255));
            hist.Calculate(new Image<Gray, byte>[] {imgB[0] }, false, null);
            Mat m = new Mat();
            hist.Copy(m);

            histogramBox1.AddHistogram("Blue", Color.Blue, m);
        }
    }
