Hello,

I want to do the z direction median filter to generate a median value in
different slice for background substraction. I have some problem in
debug the following plugin. Can anybody help me with it.

Thank you very much.

Best wishes,
Junsheng Wang

public class Z_Direction_Median_Filter implements PlugInFilter{
   
      int m = stack.getWidth();
        int n = stack.getHeight();
        int dimension = m*n;
        int nSlices = stack.getSize();
      public double[] zPixels;
      public double[] xyPixels;
      public double zMedian = 0;      
public void run() {
        if (nSlices==1)
       exit("Stack required");
  for (j=1; j<=dimension; j++)
   for (i=1; i<=nSlices; i++) {
       setSlice(i);
       zPixels[i]=(double)stack.getPixels(i);
   }
       zMedian=median(zPixels);
         xyPixels[j]=zMedian;
  }    
  run("Duplicate...", "title=zMedian");
  run("Select All");    
  setColor(xyPixels);
  run("Fill");
}
private static double median(double array[]){
        Arrays.sort(array);
        int len = array.length;
        if(len%2==0)return((array[(len/2)-1]+array[len/2])/2);
        else return array[((len-1)/2)];
    }  
}
