Question

我需要比较两个相似图像中的像素，创建一个保存的第三个图像，其中两个图像之间相同的像素变为蓝色。代码还需要在开始比较之前检查图像是否具有相同的大小，如果它们的大小不同，则会向控制台退出并出错。这是我的代码。我仍然需要覆盖两个图像并将相似的像素转为蓝色。我需要使用Filechooser.pickAFile，但除此之外，我完全迷失了如何去做。

    String fileName = FileChooser.pickAFile();
    FileChooser.setMediaPath ( fileName );
    System.out.println (fileName);
    p1 = new Picture( fileName );
    
    // Width and length of original picture
    int width1 = p1.getWidth();
    int height1 = p1.getHeight();
    Pixel[] pixelArray1 = p1.getPixels();
    System.out.println(pixelArray1.length + "pixels");
    System.out.println("");
    
    
    
    // Modified picture
    Picture p2;            // create the variable
    String filename2;
    filename2 = FileChooser.pickAFile();
    FileChooser.setMediaPath ( filename2 );
    System.out.println (filename2);
    p2 = new Picture( filename2 );
    
    //Width and Height of manipulated picture
    int width2 = p2.getWidth();
    int height2 = p2.getHeight();
    Pixel[] pixelArray2 = p2.getPixels();
    System.out.println(pixelArray2.length + "pixels");
    System.out.println("");
    
    //checking that the images are the same size
    if ((width1 != width2) || (height1 != height2)) 
     {
      System.err.println("Error: Image dimensions do not match");
      System.exit(1);
     }
    
    // Save Third image with similarities highlighted in blue.
    String filename3;
    filename3 = FileChooser.pickAFile();
    p2.write( filename3 );
  }

}// end

比较图像的像素相似度
