c# - 将图像转换为结构

Question

有没有办法将 EmguCV IImage 转换为 EmguCV 结构？

Image<Bgr, Byte> Frame;           // current frame from camera
Image<Bgr, Byte> Previous_Frame;  // previous frame aquired
Image<Bgr, Byte> Difference;      // difference between the two frames

double ContourThresh = 0.003; //stores alpha for thread access
int Threshold = 60; //stores threshold for thread access

private void ProcessFrame(object sender, EventArgs arg)
{
    if (Frame == null) 
    {
        Frame = imageBox1.Image; //error
        Previous_Frame = imageBox2.Image; //error
    }
    else
    {
        Frame = imageBox1.Image;//error
        Previous_Frame = imageBox2.Image;//error

        Difference = Previous_Frame.AbsDiff(Frame); 
        Difference = Difference.ThresholdBinary(new Bgr(Threshold, Threshold, Threshold), new Bgr(255, 255, 255)); //if value > 60 set to 255, 0 otherwise 

        Previous_Frame = imageBox2.Image;
    }
}

我得到:

Error 14 Cannot implicitly convert type Emgu.CV.IImage to Emgu.CV.Image<Emgu.CV.Structure.Bgr,byte>. An explicit conversion exists (are you missing a cast?) d:\ece design project\aslt software\aslt software\seatplan.cs 917 25 ASLT Software

我试图找出两个图像框之间的区别，imageBox1和 imageBox2 .

• imageBox1是来自相机捕获的图像的处理图像，而 * imageBox2是 imageBox1 中的图像，已保存到 ms access 数据库中..

我想做的是在数据库中找到与 imagebox1 匹配的图像。我在这里做的是正确的还是你们有比使用 absdiff 更好的选择？

在浏览了一些文章后，我找到了自己问题的答案。

这就是我做的..

            Frame = new Image<Bgr, Byte>(imageBox1.Image.Bitmap);
            Previous_Frame = new Image<Bgr, Byte>(imageBox2.Image.Bitmap);
