### Question:
ImageInstanceVisualizer { public ImageRepresentation drawImportance(AnchorCandidate anchorCandidate) { final Map<Integer, Double> importanceMap = new HashMap<>(); while (anchorCandidate != null) { importanceMap.put(anchorCandidate.getAddedFeature(), anchorCandidate.getAddedPrecision()); anchorCandidate = anchorCandidate.getParentCandidate(); } return drawImportance(importanceMap); } ImageInstanceVisualizer(ImageInstance originalInstance); static void showOnScreen(ImageRepresentation type); ImageRepresentation drawResult(Collection<Integer> features); ImageRepresentation drawSuperpixeled(); ImageRepresentation drawImportance(AnchorCandidate anchorCandidate); ImageRepresentation drawImportance(Map<Integer, Double> featureImportanceMap);  }### Answer:
@Test @Disabled public void drawImportance() throws Exception { URL resource = Thread.currentThread().getContextClassLoader().getResource("dog.jpg"); de.viadee.xai.anchor.adapter.image.BufferedImageRepresentation imageRepresentation = new BufferedImageRepresentation(ImageIO.read(resource)); ImageInstance imageInstance = SLICSuperpixelation.extractSuperpixels(imageRepresentation, 50, 0.15f); de.viadee.xai.anchor.adapter.image.ImageInstanceVisualizer visualizer = new ImageInstanceVisualizer(imageInstance); Map<Integer, Double> importanceMap = new HashMap<>(); for (int i = 0; i < imageInstance.getFeatureCount(); i++) { importanceMap.put(i, 0D); } ImageRepresentation expectedEmpty = visualizer.drawImportance(importanceMap); for (int i = 0; i < expectedEmpty.getWidth(); i++) for (int j = 0; j < expectedEmpty.getHeight(); j++) assertEquals(expectedEmpty.getPixel(i, j), Color.HSBtoRGB(0, 0, 0)); double stepSize = 1D / imageInstance.getFeatureCount(); importanceMap = new HashMap<>(); for (int i = 0; i < imageInstance.getFeatureCount(); i++) { importanceMap.put(i, 1 - stepSize * i); } }
