Fig. 4: Segmentation uncertainty in two graphite electrodes for lithium-ion batteries.
From: Quantifying the unknown impact of segmentation uncertainty on image-based simulations
Electrode I (a–c) and Electrode II (e–g). a, e 2D slices of the 3D X-ray CT image. b, f Histogram of voxel intensities for the whole image (gray), for voxels segmented as particle (red), and for voxels segmented as void (green). The BRISQUE image quality score is overlaid on the histograms and quantitatively measures the perceptual quality of an image, with a lower score indicating superior image quality. c, g Segmentation in transparent orange overlaid on the original 2D image. d, h Uncertainty distribution for both electrode images, with electrical conductivity in (d) and tortuosity in (h), both relative to their mean values.
