穷举模板匹配有错误'索引超出了数组的范围'。 [英] Exhaustive Template Matching have error 'Index was outside the bounds of the array'.

问题描述

我想匹配两个具有相同特征的图像。 I 使用Aforge.Net的穷举模板匹配来做到这一点。当我比较相同的图像并给出相似值1时，它会起作用，但是我得到一个错误  索引超出了数组 b

I want to match two image which have same characteristic. I  use Exhaustive Template Matching from Aforge.Net to do that. It work when i compare same image and give 1 for similarity value, but i getting an error Index was outside the bounds of the array in

akurasiBox.Text = matchings[0].Similarity.ToString();

这是代码

This is the code

private void kenali_citra_Click(object sender, EventArgs e)
        {
            
            pictureBox3.Image.Save(@"E:\bismillah\bismillah\temp.jpg", ImageFormat.Jpeg);

            ExhaustiveTemplateMatching tm = new ExhaustiveTemplateMatching();

            System.Drawing.Image z = System.Drawing.Image.FromFile(@"E:\SKRIPSI\bismillah\bismillah\temp.jpg");
            Rectangle cloneRects = new Rectangle(0, 0, mybitmaps.Height, mybitmaps.Width);
            PixelFormat formats = pictureBox3.Image.PixelFormat;
            Bitmap clonebitmaps = mybitmaps.Clone(cloneRects, PixelFormat.Format8bppIndexed);
            Bitmap cUji = clonebitmaps;
            

            System.Drawing.Image a = System.Drawing.Image.FromFile(@"E:\bismillah\Citra Template Terproses\07.jpg");
            Bitmap MB = new Bitmap(a);           
            Rectangle cloneRect = new Rectangle(0, 0, MB.Height, MB.Width);           
            Bitmap clonebitmap = MB.Clone(cloneRect, PixelFormat.Format8bppIndexed);
            Bitmap cTemp = clonebitmap;
           
            {
                TemplateMatch[] matchings = tm.ProcessImage(cUji, cTemp);
                
                akurasiBox.Text = matchings[0].Similarity.ToString();
                
            }
}

请帮助解决我的问题。

推荐答案

可能是数组是空的。检查
的值 matchings.Length ：

   ;
akurasiBox.Text = matchings.Length == 0？ "不匹配" ：matchings [0] .Similarity.ToString（）;

   akurasiBox.Text = matchings.Length == 0 ? "No matches" : matchings[0].Similarity.ToString();
