The program in Java that compares any 2 images and shows the differences visually by drawing rectangles. The Usages of the image-comparison can be found here Usage Image Comparison

• Implementation is using only standard core language and platform features, no 3rd party libraries and plagiarized code is permitted.
• Pixels (with the same coordinates in two images) can be visually similar, but have different values of RGB. 2 pixels are considered to be "different" if they differ more than 10% from each other.
• The output of the comparison is a copy of one of the images. The differences are outlined with red rectangles as shown below.
• No third party libraries or borrowed code are in usage.

To clone and build this project, run the following commands:

git clone https://github.com/romankh3/image-comparison
cd image-comparison
./gradlew check jar

This will compile, run the tests, and create a runnable jar at ${projectDir}/build/libs.

• Added publishing to JCenter

• fixed bug #11(finally!!)

The program in Java that compares any 2 images and shows the differences visually by drawing rectangles.

• Implementation is using only standard core language and platform features, no 3rd party libraries and plagiarized code is permitted.
• Pixels (with the same coordinates in two images) can be visually similar, but have different values of RGB. We are only consider 2 pixels to be "different" if the difference between them is more than 10%.
• The output of the comparison is a copy of one of the images image with differences outlined with red rectangles as shown below.
• No third party libraries and borrowed code are not using.

This library can be used as a command-line utility to compare two images.

After building with ./gradlew jar, you will find the runnable jar at ${projectDir}/build/libs.

To compare two images in files a.png and b.png, for example, run:

java -jar image-comparison.jar a.png b.png

To save the result image in a third file, say comparison.png, just give that file as a third argument:

java -jar image-comparison.jar a.png b.png comparison.png

To show more usage details, run:

java -jar image-comparison.jar -h

<dependency>
    <groupId>com.github.romankh3</groupId>
    <artifactId>image-comparison</artifactId>

</dependency>

compile 'com.github.romankh3:image-comparison:2.1.0'

class Example {
    public static void main( String[] args ) {
        // load the images to be compared
        BufferedImage bufferedImage1 = ImageComparisonTools.readImageFromResources("image1.png");
        BufferedImage bufferedImage2 = ImageComparisonTools.readImageFromResources("image2.png");
        
        // where to save the result (leave null if you want to see the result in the UI)
        File result = new File( "result.png" );
        
        // compare them
        BufferedImage drawnDifferences = new ImageComparison( image1, image2, result ).compareImages();
    }
}

Run the ./run.sh script to run the demo.

You will get the result of comparing two images. The images, which are using:
