- class mindspore.dataset.vision.AutoAugmentPolicy[源代码]
AutoAugment policy for different datasets.
Possible enumeration values are: AutoAugmentPolicy.IMAGENET, AutoAugmentPolicy.CIFAR10, AutoAugmentPolicy.SVHN.
Each policy contains 25 pairs of augmentation operations. When using AutoAugment, each image is randomly transformed with one of these operation pairs. Each pair has 2 different operations. The following shows all of these augmentation operations, including operation names with their probabilities and random params.
AutoAugmentPolicy.IMAGENET: dataset auto augment policy for ImageNet.
Augmentation operations pair: [(("Posterize", 0.4, 8), ("Rotate", 0.6, 9)), (("Solarize", 0.6, 5), ("AutoContrast", 0.6, None)), (("Equalize", 0.8, None), ("Equalize", 0.6, None)), (("Posterize", 0.6, 7), ("Posterize", 0.6, 6)), (("Equalize", 0.4, None), ("Solarize", 0.2, 4)), (("Equalize", 0.4, None), ("Rotate", 0.8, 8)), (("Solarize", 0.6, 3), ("Equalize", 0.6, None)), (("Posterize", 0.8, 5), ("Equalize", 1.0, None)), (("Rotate", 0.2, 3), ("Solarize", 0.6, 8)), (("Equalize", 0.6, None), ("Posterize", 0.4, 6)), (("Rotate", 0.8, 8), ("Color", 0.4, 0)), (("Rotate", 0.4, 9), ("Equalize", 0.6, None)), (("Equalize", 0.0, None), ("Equalize", 0.8, None)), (("Invert", 0.6, None), ("Equalize", 1.0, None)), (("Color", 0.6, 4), ("Contrast", 1.0, 8)), (("Rotate", 0.8, 8), ("Color", 1.0, 2)), (("Color", 0.8, 8), ("Solarize", 0.8, 7)), (("Sharpness", 0.4, 7), ("Invert", 0.6, None)), (("ShearX", 0.6, 5), ("Equalize", 1.0, None)), (("Color", 0.4, 0), ("Equalize", 0.6, None)), (("Equalize", 0.4, None), ("Solarize", 0.2, 4)), (("Solarize", 0.6, 5), ("AutoContrast", 0.6, None)), (("Invert", 0.6, None), ("Equalize", 1.0, None)), (("Color", 0.6, 4), ("Contrast", 1.0, 8)), (("Equalize", 0.8, None), ("Equalize", 0.6, None))]
