I am introducing a program that I code today (the program belongs to me)
The program helps to find the similarity between the two pictures :)

> Use;
After opening the program, we select 2 pictures with the select buttons on the left and right, Then we compare the start button with the 2 photos and the result is reflected in our screen.

Do not hesitate to comment if you encounter any problems .

> Codes to select our pictures from your computer and bring them to the screen.  (The code to be written into the button on the left side )


    Bitmap bmp1, bmp2;
    ArrayList arl = new ArrayList();
    ArrayList arl2 = new ArrayList();
    
    private void button1_Click(object sender, EventArgs e)
    {
    
    arl.Clear();
    openFileDialog1.ShowDialog();
    bmp1 = (Bitmap)Bitmap.FromFile(openFileDialog1.FileName);
    pictureBox1.Image = bmp1;
    
    for(int a=0;a<bmp1.Width;a++)
    {
    for(int b=0;b<bmp1.Height;b++)
    {
    arl.Add(bmp1.GetPixel(a, b).Name);
    }
    }
    }

> We do the same for Button 2 for the operations we did for Button 1. (The code to be written into the button on the Right side )


    private void button2_Click(object sender, EventArgs e)
    {
    arl2.Clear();
    openFileDialog1.ShowDialog();
    bmp2 = (Bitmap)Bitmap.FromFile(openFileDialog1.FileName);
    pictureBox2.Image = bmp2;
    for (int a =0;a<bmp2.Width;a++)
    {
    for (int b = 0;b<bmp2.Height;b++)
    {
    arl2.Add(bmp2.GetPixel(a, b).Name);
    }
    }
    }

-----------------------------------------------------------------------------------------------------------------------------
> The actual code we will use for comparison


    private void button3_Click(object sender, EventArgs e)
    {
    double equal = 0;
    double notequal =0;
    for (int a = 0; a < arl.Count; a++)
    {
    if (arl [a].ToString() == arl2 [a].ToString())
    {
    equal++;
    }
    else
    {
    notequal++;
    }
    }
    
    if (notequal ==0)
    {
    label1.Text = "%100";
    }
    else
    {
    if (equal>notequal)
    {
    label1.Text = "%" + Convert.ToString(100 - ((notequal * 100) / equal)).Substring(0, 5);
    }
    else
    {
    label1.Text = "%" + Convert.ToString((equal * 100) / notequal).Substring(0, 5);
    }
    }
    
    }

it will be a useful program for you,  you can develop my program in more detail . 
The program's working logic sets the similarity rate by comparing the pixels of 2 photographs. 
I hope it is useful for you, I tried to get to introduce my program and clarify which codes are used. If you have a problem or suggestions somewhere, please comment.
