Java fork of Resemble.js javascript library.

Image Comparison

• Compare two images giving a mismatch score
• create an image with a configurable visual difference
• Preprocess util to crop background, resize, fit.

Usage

You can run the TestApp.java file or:

        File imgFile1 = new File("1.jpg");
        File imgFile2 = new File("2.jpg");

        BufferedImage img1 = ImageUtils.readImage(imgFile1);
        BufferedImage img2 = ImageUtils.readImage(imgFile2);
        
        //ignore antialiasing between two images (different qualities for example)
        ResembleAnalysisOptions options = ResembleAnaylsisOptionsTemplates.ignoringAntialiasing();
        
        ResembleAnalysisResults results = new ResembleAnalysis(options).analyseImages(img1, img2);
        
        ResembleParserData dataResult = ResembleParser.parse(results.getOutputImage());

        System.out.println(String.format("File 1: '%s'\n" +
                        "File 2: '%s'\n\n" +
                        "Info: %s\n\n" +
                        "Output image:\n%s\n\n" +
                        "Options:\n%s\n\n" +
                        "Mismatch percentage: %.2f %%\n" +
                        "Analysis time: %d miliseconds\n" +
                        "Difference bounds: %s",
                imgFile1, imgFile2, dataResult, results.getOutputImage(), options,
                results.getMismatchPercentage(), results.getAnalysisTime().toMillis(),
                results.getDiffBounds()));

The image used in the comparison example was created by Daniel Rajendran

New Features:

• Resize the two images before comparing them (allowing different size and quality images comparison)
• Add templating for comparison using the thresholds available the ResembleJS Demo page http://rsmbl.github.io/Resemble.js/
• Make crop threshold customizable
• Crop the image removing the white background
