Segment an image in java

[Logan 2]

Hello,
I have a small problem with my code. I try to write java code to segment an image using the region growing approach. when I run the code it gives me exceptions. Please help me with this
The exception I get is as

java.lang.ArrayIndexOutOfBoundsException

Any help on this is appreciated. Thanks in advance.

Hello,
The exception

java.lang.ArrayIndexOutOfBoundsException

in your code is related to the following indication. Indicating you use a box that does not exist in your table. If you need more information on the exception which are there in java, then you can visit the sun's official site and their you can find more detailed information on the same and then you can identify that which is the exception you get and what you have to do when you get the exception.

Hello,
Even I get a similar kind of a exception in my program, the error is at the following line:

output [count + +] = labels [w] [h];

I use an array of 1 dimension output To store the values of "labels"(matrix) and then I go"output"As an argument in

img = createImage (new MemoryImageSource (width, height, output, 0, width));

to create my image result. So when I try to display the size of each table using.

System.out.println (width);
System.out.println (height);
System.out.println (labels.length);
System.out.println (output.length);

If you know where I am wrong in then code then please guide me with the correct code. Thanks in advance.

Hello,
This is my updated code, please have a look at it

private int w, h;
 private int[] [] lbl;
 
 private void Growing (BufferedImage image) (
w = image.getWidth ();
image.getHeight h = ();
lbl = new int[w] [h];
Stack <Point> mustDo = new <Point> Stack ();
    
      for(int h = 0 h <h h + +)
          for(int w = 0, w <w; w + +)
         (lbl [w] [h] = 0;)
/ / to simplify the code I set the seed (seed) to start my choice (x = 5, y = 8)
      int x = 5;
      int y = 8;
      lbl [x] [y] = 1;
      mustDo.add (new Point (x, y));
      while(mustDo.size ()> 0)
           (
           ThisPointer mustDo.get = Point (0); mustDo.remove (0);
           / / Check 8-neighborhood
            for(int th =- 1; th <= 1; th + +)
              for(int tw =- 1; tw <= 1; tw + +)
                (
                int thisPoint.x + rx = tw;
                int ry = thisPoint.y + th;
              
                if ((rx <0) | | (ry <0) | | (ry> = h) | | (rx> = w)) continues;
                int RGB1 = buffeurActuel.getRGB (rx, ry);
		        int RGB2 = buffeurActuel.getRGB (thisPoint.x, thisPoint.y);
			    if (lbl [rx] [ry] <0) (            	    
			       if (RGB1 == RGB2) (
                   mustDo.add (new Point (rx, ry));
                   lbl [rx] [ry] = 1;
                  
                   )
                )
             )
          ) 
    
     int [] opt = new int [w * h];
     int cnt = 0;
     for (int h = 0 h <h = h + +)
    	 for(int w = 0, w <= w; w + +)
    output [cnt + +] = lbl [w] [h];
       
}

Hello,
I think I have solution for you code and that too it works with me correctly, in your loop, it does not take a <= height but a <height. same for width.
Here is the code for it

for (int a = 0 a <height a + +)
    	 for(int w = 0, w <width; w + +)
    out [c + +] = labels [w] [a];

Hope the following will help you.

Hello,
I think the soltuion you have posted works with me. To work on the segmentation of an image by monographic growth area I am about to use BufferedImage when my coach is my intention to convert the image PixelsGraber to facilitate and during my research on the net I noticed the use of PlannerImage with JMF to achieve segmentation by region growing. What is the best choice for good results?

[vishal.upad008]

cud u please send me the whole code for segmentation... i m in desperate need of it.....
thnx i advance.....

[vishal.upad008]

i m a b.tech final year student n i m working on a project for detecting shadow in images which is to b implemented in java.
for dat, first the image has to b converted in grayscale which i hav done.
The main problem is dat dis gray image has to b segmented. I dont kn how to do dis in java...
i an do dat in matlab, but in java i m facing much difficulties.
I m bound to make dis project in java.

Cud u please send me full image segmentation code in java at my Email id (vishal.upad008@gmail.com).
I wud b very thankful to u....

Thanks & Regards
