Fig. A.8:
A direct comparison between global patch shuffling (Chen et al., 2019a) and our local pixel shuffling. (a) illustrates ten example images undergone local-shuffling and patch-shuffling independently. As seen, the overall anatomical structure such as individual organs, blood vessels, lymph nodes, and other soft tissue structures are preserved in the transformed image through local-shuffling. (b) presents the performance on five target tasks, showing that models pre-trained by our local-shuffling noticeably outperform those pre-trained by patch-shuffling for cross-domain transfer learning (BMS).
