Measuring Inter-image distances

Euclidean Distance:

The simple method for comparing disagreement among two images is to take their per-pixel difference. This is sensitive to small misalignments though.

Shuffle Distance:

In our experiments we have defined image distance as the shuffle distance between two images, as illustrated below

3#3 = 6#6 The computation of the shuffle distance

3#3 = 7#7 The product of a shuffle transform

3#3 = 8#8 The effect of increasing the shuffle radius
