How to compare two images, check two image are same or not

You can compare two images using imagemagick.
You can download imagemagick from here. Version must be greater than 6.0. (like ImageMagick-6.4.3-Q16). Suppose you install in "C:\Program Files " folder then you can run command from this location C:\Program Files\ImageMagick-6.4.3-Q16>

After successfully installation you can use this below command
C:\Program Files\ImageMagick-6.4.3-Q16>compare -metric AE 5001.MAIN.jpg 5002.MAIN.jpg difference.jpg
if it returns value 0 means both images are same.

Even you can use -verbose attribute with this command to get more output.
C:\Program Files\ImageMagick-6.4.3-Q16>compare -verbose -metric AE 5001.MAIN.jpg 5002.MAIN.jpg difference.jpg

You can check this command with two different images, two same images.

There are some more command
C:\Program Files\ImageMagick-6.4.3-Q16> compare -compose src rose.jpg reconstruct.jpg difference.png
C:\Program Files\ImageMagick-6.4.3-Q16> compare -verbose -metric mae rose.jpg reconstruct.jpg difference.png
C:\Program Files\ImageMagick-6.4.3-Q16> compare -channel red -metric PSNR rose.jpg reconstruct.jpg difference.png

You can get more info from these link

    How did you use this command in Java. Is that possible to use in web based application and where to have the ImageMagick-6.5.3-7.i386.rpm in that case and how to call in jsp or servlet?

    Hi Raf,

    Yes, you can use ImageMagick command in java and servlet very easily. Please visit my this blog (http://binodjava.blogspot.com/2009/05/how-to-use-runtimegetruntimeexec-how-to.html) for how to use any command in java. In that blog, instead of
    command.add("cmd.exe");
    command.add("/c");
    command.add("copy");
    command.add(sourceFile);
    command.add(destFile);

    You have to use

    command.add("C:\\Program Files\\ImageMagick-6.4.3-Q16\\compare.exe");
    command.add("-metric AE ");
    command.add(" 5001.MAIN.jpg ");
    command.add(" 5002.MAIN.jpg ");
    command.add(" difference.jpg");

    Try yourself, if not work I will give complete code on how to compare image in java using imageMagick.

    Binod, if you call native windows commands from a Java program, it sort of defeats the point of using Java, doesn't it ? Java programs should be compatible with any operating system, not just windows.
