Result from a group analysis on diseased vs. normal groups using synthetic PIB images. a) a template PIB image used for the mean μ, b) p–value map in −log10 scale from the group analysis using images without the systematic variation (serving as the ground truth), c) p–value map in −log10 scale from the group analysis using images with systematic variation, d) p–value map in −log10 scale from the group analysis using WKD on images with systematic variation. We can see that using WKD, we can detect group differences even when there is a systematic variations in the images.
