Comparison of the mean Dice-scores and their standard deviation between different initialization methods for the UZ Ghent dataset.

<p>The highest Dice-score per NMF method and per tissue class is marked in bold. * indicates statistically significantly higher Dice-scores with SPA initialization compared to direct SPA endmember extraction (right column), using a one-tailed Wilcoxon signed rank test (<i>p</i> < 0.05).</p
