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;
    }
}

我得到了：

错误14无法将类型Emgu.CV.IImage隐式转换为Emgu.CV.Image<Emgu.CV.Structure.Bgr,byte>。存在显式转换（您是否缺少演员？）d：\ ece design project \ aslt software \ aslt software \ seatplan.cs 917 25 ASLT Software

我正在尝试区分两个图像框imageBox1和imageBox2。

imageBox1是由相机捕获的图像处理过的图像，而* imageBox2是来自imageBox1的图像，保存到ms访问数据库。

我要做的是在数据库中找到与imagebox1匹配的图像..这是我在这里做的正确还是你们有比使用absdiff更好的选择？

在浏览了一些文章后，我发现了自己的问题答案。

这就是我所做的..

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