These functions are exposed with the function
from imagenet_c import corrupt corrupt(<image>, corruption_number=0)
corrupt function looks like
def corrupt(x, severity=1, corruption_name=None, corruption_number=-1): """ :param x: image to corrupt; a 224x224x3 numpy array in [0, 255] :param severity: strength with which to corrupt x; an integer in [0, 5] :param corruption_name: specifies which corruption function to call; must be one of 'gaussian_noise', 'shot_noise', 'impulse_noise', 'defocus_blur', 'glass_blur', 'motion_blur', 'zoom_blur', 'snow', 'frost', 'fog', 'brightness', 'contrast', 'elastic_transform', 'pixelate', 'jpeg_compression', 'speckle_noise', 'gaussian_blur', 'spatter', 'saturate'; the last four are validation functions :param corruption_number: the position of the corruption_name in the above list; an integer in [0, 18]; useful for easy looping; 15, 16, 17, 18 are validation corruption numbers :return: the image x corrupted by a corruption function at the given severity; same shape as input """ ...
