如何從給定的一組差異像素值形成圖像？

Question

我已經找到了差異像素。我需要將這些差異像素值分組到區域中。應該隨機選擇一個種子像素。現在該區域必須生長爲8個連通區域。在這裏我附上了我到現在爲止所實施的代碼。所以請建議我執行上述操作。

import java.io.FileWriter;

import java.awt.image.BufferedImage; 
public class imageMSE 
{ 
    public static String img; 
    public static int no; 
    public static BufferedImage[] image; 
    public static BufferedImage[] res; 

    public static void getImage() 
    { 
     Scanner in=new Scanner(System.in); 
     System.out.println("\nPLEASE ENTER THE TOTAL NUMBER OF IMAGES:"); 
     no=in.nextInt(); 
     System.out.println("\nTHE NUMBER OF IMAGES ARE: "+no); 
    image=new BufferedImage[no]; 
     for(int i=0;i<no;i++) 
     { 
      image[i]=null; 
     } 
     try 
     { 
      Scanner in1=new Scanner(System.in); 
      System.out.println("\nPLEASE ENTER THE PATH FOR IMAGES:"); 
      for(int i=0;i<no;i++) 
      { 
       System.out.println("\nPLEASE ENTER THE PATH FOR IMAGE["+(i+1)+"] :"); 
       img=in1.nextLine(); 
       image[i] = ImageIO.read(new File(img)); 
      } 
     } 
     catch (IOException e) 
     { 
       e.printStackTrace(); 
      }

Answer 1

創建規模的新形象，你想

BufferedImage image = new BufferedImage(width, height, BufferedImage.TYPE_INT_RGB); 

然後訪問單個像素的「畫」

image.setRGB(x, y, rgb); 

你最新的代碼是接近的，但有一些問題...

您不需要任何「圖形」代碼。刪除此

Graphics g=res.getGraphics(); 

在你的JFrame

這

g.drawImage(res,0,0,null); 

要添加2個板。只需使用一個。

刪除

JPanel result=new JPanel(); 

和刪除

result.add(resl); 
frame.add(result); 

只是新的圖像添加到現有的面板

picPanel.add(resl)
