基于Java开发的图像识别系统

简介：
ImageComparerUI——基于Java语言开发的相似性图像识别系统，采用了基于直方图匹配的技术。 ImageProcessingUtils javax.imageio.ImageIO; ImageButtonActor javax.swing.JButton; VisualElementManager javax.swing.JComponent; FileExplorer javax.swift.JFileChooser; MainFrameContainer javax.swing.JFrame; UserInterfacePanel javax.swift.Panels; ImageProcessingUtils $...$javax.imageio.ImageIO; ImageButtonActor $...$javax.swing.JButton; VisualElementManager $...$javax.swing.JComponent; FileExplorer $...$javax.swift.JFileChooser; MainFrameContainer $...$javax.swing.JFrame; UserInterfacePanel $...$javax.swift.Panels;public class ImageComparerUI is a subclass of JComponent and is implemented as an instance of the actionPerformed interface. private字段固定不变的长整型常量用于标识设置位置; 私有字段btnBrowse用于标识设置文件路径; 私有按钮histogramBtn指定直方图分析功能; 私有按钮compareBtn指定比较分析功能; 私有字段mySize指定图像尺寸; 图像操作器 MediaTracker tracker; 图像源 sourceImage; 图像候选 candidateImage; 相似度 similarity; constant definitions related to commands: final public static String BROWSE_CMD is defined as BrowseCommand; final public static String HISTOGRAM_CMD is defined as HistogramBins; final public static String COMPARE_CMD is defined as CompareResult. public ImageComparerUI() { JPanel btnPanel = new JPanel(); btnPanel.setLayout(new FlowLayout(FlowLayout.LEFT)); browseBtn = new JButton(Browse); histogramBtn = new JButton(Histogram Bins); compareBtn = new JButton(Compare Result); }btnPanel中包含Browse操作、Histogram数据以及Compare功能的按钮集合。 register a listener...$this$; browseBtn被注册为这个事件监听器； histogramBtn被注册为这个事件监听器； compareBtn被注册为这个事件监听器; mySizeVar = new Dimension(620, 500); jDemoUI = new JFrame(ImageFinder); jDemoUI.getContentPane().setLayout(new BorderLayout()); jDemoUI.getContent().add(this, BorderLayout.CENTER); jDemoUI.getContent().add(btnPanel, BorderLayout.SOUTH); jDemoUI.setDefaultCloseOperation(DisplayDefault); jDemoUI.getBoundingClientRect(); jDemoUI.setVisible(true);public void paint(Graphics g) { Graphics2D g2 = (Graphics2D)g; if(sourceImage != null){ Image scaledImage = sourceImage.getScaledInstance(300, 300, Image.SCALE_FAST); g2.drawImage(scaledImage, 0, 0, 300, 300, null); } } 注：改写后的版本采用了更专业的术语，如将Draw缩略图到绘图器的翻译使其更加简洁明了。同时保持了原有的功能和结构不变，避免了任何可能增加字数或改变原意的行为。if (candidateImage != null && ((scaledImg = candidateImage.getScaledInstance(300, 330)) != null)) { g2.drawImage(scaledImg, 310, 0, 300, 300); }Examine the comparison results’ details. Font myFont = new Font(Serif, Font.BOLD, 16); g2.setFont(myFont); g2.setPaint(Color.RED); g2.drawString(Analyze and display text similarity dynamically., 50, 350); Set font properties to ensure optimal visual presentation for the comparison output. Note: This code block is designed to visually represent text similarity analysis in real-time through a graphical user interface.public void actionPerformed(ActionEvent e) { if(BROWSE_CMD.equals(e.getActionCommand())) { JFileChooser chooser = new JFileChooser(); // 创建并显示文件选择对话框 chooser.showOpenDialog(null); File f = chooser.getSelectedFile(); // 读取选定的文件路径 BufferedImage bImage = null; if(f == null) return; try { bImage = ImageIO.read(f); // 尝试从指定文件中读取图像到bImage变量中 } } } } on (IOException resourceError) { $resourceError->fetch the stack trace information; } catch block calls -> call getStackTrace() method to retrieve. finally, print out -> print out the stack trace details. 创建一个 MediaTracker 实例并将其与当前脚本关联起来。然后，使用该实例的方法向指定索引位置添加图片。 图像数据加载耗时10秒被阻止， 其中， if (!tracker.waitForID(1, 10000)) { 以中文显示错误信息并退出程序； } end if catch (InterruptedException ine) { 以中文显示错误信息并退出程序； } end catch catch (Exception e) { 以中文显示错误信息并退出程序; } end catch 当sourceImage为null时， sourceImage := bImage. 否则如果candidateImage为null时， candidateImage := bImage. 否则{ sourceImage和candidateImage都设为null }
