Hi,<br>
<br>
Thank you, but talk of reducing the number of pixels without changing the picture size. The vtkImageResample change the spacing. Since no change?<br>
<br>

<div class="Ih2E3d">whart do you understand as "image quality" ?<br>
<br>
the amount of noise? sharpness of boundaries?<br>
<br>
vtkImageNoiseSource might help to add artificial noise.<br>
