[Insight-users] How to access a value from the index array?

[D, Yamini]

Hi,

I am working on a problem which requires the access of certain values(every 5th value) from an "index" array.
This is the part of the code which fetch the pointset  of the pixels which are white in the image. The pointset are stored in "index".
Outside the for loop,  I want to access every 5th value from the array index[0] (x-values) and from array[1] (y-values).


//code
InputImageType::IndexType index;

int i,j;

for (i=0;i<size_x;i++){
       for (j=0;j<size_y; j++){
              index[0]=i;  // x-values
              index[1]=j;  // y-values

InputImageType::PixelType pixelValue = image->GetPixel(index);
if(pixelValue==255)
cout<<index[0]<<"    " << index[1]<<endl;

       }
}



Can anyone guide me to solve this.
Thank you,
Yamini.D
