    Yup.. Irrespective of size of the image, I need to write a JAVA code, where it'l compare the image given as an input with another image already contained in my database and return true if comparison matches. For Eg., if I give an image of computer, my code should be able to compare with images of computer in my database and return the o/p.. Database codin part, leave it upto me. I just need help in, how Java compares two images..

    Hi Gulnaz,

    I searched for your query on the net and found this result:

    <a href="https://mindmeat.blogspot.com/2008/07/java-image-comparison.html" target="_blank" rel="noopener noreferrer">Mind Meat: Java Image Comparison / Motion Detection</a>

    Does that help?

    import java.awt.event.*;
    /*<Applet code="comp" height=400 width=400></applet>*/
    public class comp extends JApplet implements ActionListener
    {
    Button b;
    String str,str1;
    public void init()
    {
    b=new Button("submit");
    add(b);
    setLayout(new FlowLayout());
    b.addActionListener(this);
    }
    public void actionPerformed(ActionEvent e)
    {
    repaint();
    byte b1[]=new byte[60000];
    byte b2[]=new byte[60000];
    try
    {
    int i=0;
    FileInputStream f1=new FileInputStream("kk.jpg");
    f1.read(b1);
    FileInputStream f2=new FileInputStream("kk1.jpg");
    f2.read(b2);
    while(b1!=3 || b2!=3)
    {
    if(b1==b2)
    i++;
    else
    {
    str="not matched";
    break;
    }
    }
    if(b1[i-1]==b2[i-1])
    {
    str="matched";
    str1=Integer.toString(i);
    }
    }
    catch(Exception ee)
    {
    System.out.println("Exception caught");
    }
    }
