However, these methods were ineffective in our experiment. As we explain in Section 3.2, our test-time augmentation space consists of 12 operations. Figure 4 shows a selected data sample and its augmented versions. PIL.ImageEnhance.Sharpness function gives a blurred image with parameters less The original image was distorted by some corruptions, such as rotation and noise. We use up-to 64 nodes to parallelize data-generating process.
