是否包含截图图像？ [英] Contains screenshot image or not ?

问题描述

所以，我正在使用Windows Forms在C＃中创建一个项目，我只有一个问题。我必须使用屏幕截图来显示图像。如果屏幕截图包含其中一个图像，则必须返回其路径（路径不重要）。所以我需要一个方法，如果截图包含Image，则返回true，否则返回false。在这种情况下，返回值并不重要。



我尝试过：



我试图使用以下代码，但它总是返回False，这意味着屏幕截图不包含这些图像。我使用以下代码：

So, I am making a Project in C# with Windows Forms and I have only one Problem. I have to campare images with Screenshot. If Screenshot contains one of those images it have to return it's Path(Path isn't Important). So I need a Method that can return true if Screenshot contains Image and returns false if it doesn't. In this case return Value isn't important.

What I have tried:

I have tried to use following Code but it is always returning False, it means that Screenshot contains none of those images. I am using following Code:

public static class imageCompare
{
    public static string[] Compare(Bitmap bitmap)
    {        
        string[] addressArray = Directory.GetFiles(Path.Combine(Directory.GetCurrentDirectory(), "Kartebi2"), "*.png");

        string[] imageAddress = new string[addressArray.Length];
        Bitmap[] bitmap1 = new Bitmap[36];
        Bitmap[] bitmapImage = new Bitmap[36];

        for (int i = 0; i < bitmap1.Length; i++)
        {
            bitmap1[i] = (Bitmap)System.Drawing.Image.FromFile(addressArray[i]);

            bitmapImage[i] = Form1.ConvertToFormat(bitmap1[i], System.Drawing.Imaging.PixelFormat.Format24bppRgb);
        }

        for (int i = 0; i < bitmapImage.Length; i++)
        {
            if(Matching.Compare(bitmap, bitmapImage[i]))
                imageAddress[i] = addressArray[i];
            else
                imageAddress[i] = null;
        }

        return imageAddress;
    }
}

public static class Matching
{
    public static bool Compare(this Bitmap template, Bitmap bmp)
    {
        const int divisor = 4;
        const int epsilon = 10;

        ExhaustiveTemplateMatching etm = new ExhaustiveTemplateMatching(0.9f);
        TemplateMatch[] tm = etm.ProcessImage(new ResizeNearestNeighbor(template.Width / divisor, template.Height / divisor).Apply(template),
                                              new ResizeNearestNeighbor(bmp.Width / divisor, bmp.Height / divisor).Apply(bmp));
        if (tm.Length == 1)
        {
            Rectangle tempRect = tm[0].Rectangle;

            if (Math.Abs(bmp.Width / divisor - tempRect.Width) < epsilon && Math.Abs(bmp.Height / divisor - tempRect.Height) < epsilon)
            {
                return true;
            }
        }
        return false;
    }
}

所以如果有人知道如何做这个比较请告诉我。

So if someone has other idea how to do this comparison tell me please.
