[Insight-users] Cut ROI from a image by giving the mask

[Xi LIANG]

Dear all,

I am trying to cut a ROI from the fixed image based on the mask of ROI. Both fixed image and ROI mask are in the same format 128 X 128 X 124 as input. I can cut the image properly by using the following code (only the core part, and the whole code are attached. I have two questions here. Firstly, I just feel this is not the right way to do, there should be some function to do this. Secondly, I dont know how to get the total index number in one dimension, and I manually put the 128, 128, 124 into the code.

  for(i = 0; i < 128; i++)  {		  std::cerr << i << std::endl;	  for(j = 0; j < 128; j++)	  {		  for(k = 0; k < 124; k++)		  {			  pixelLocation[0] = i;			  pixelLocation[1] = j;			  pixelLocation[2] = k;			  inputPixelValue = fixedImage->GetPixel(pixelLocation);			  maskPixelValue = maskImage->GetPixel(pixelLocation);			  pixelValue = inputPixelValue * maskPixelValue;			  outputImage->SetPixel( pixelLocation, pixelValue);		  }	  }  }
