TUTORİAL - Find the similarity between two images with C#

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 .

Overall design image of the program;
(ToolBox : 2 groupBox, 2 pictureBox , 3 Button , 1 Label and openDialog )

---

Code Design;
Important : using.System.Collections; "Do not forget to add your class"

---

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);
}
}

}

Result;

---

Test 1 ;

Test 2 ;

---

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.
