<div>Hi Raul,</div>
<div> </div>
<div>You could try using vtkImageAccumulator like this:</div>
<div> </div>
<div>vtkImageAccumulate acc = new vtkImageAccumulate();</div>
<div>acc.SetInput(imageReader.GetOutput());<br>acc.Update();<br>double[] max = acc.GetMax();</div>
<div>double[] min = acc.GetMin();</div>
