Pixelwise mean of the normalized local grammages of the nonwoven FL1 for four lateral resolutions. The images consist of \(2\, 048\times 2\, 048\) pixels: a) pixel size \(6.734~\upmu \text{m}\), b) pixel size \(3.367~\upmu \text{m}\), c) pixel size \(1.684~\upmu \text{m}\), d) pixel size \(0.842~\upmu \text{m}\)
