参数

  • policy – [in] An enum for the data auto augmentation policy (default=AutoAugmentPolicy::kImageNet).

    • AutoAugmentPolicy::kImageNet, AutoAugment policy learned on the ImageNet dataset.

    • AutoAugmentPolicy::kCifar10, AutoAugment policy learned on the Cifar10 dataset.

    • AutoAugmentPolicy::kSVHN, AutoAugment policy learned on the SVHN dataset.

  • interpolation – [in] An enum for the mode of interpolation (default=InterpolationMode::kNearestNeighbour).

    • InterpolationMode::kNearestNeighbour, Interpolation method is nearest-neighbor interpolation.

    • InterpolationMode::kLinear, Interpolation method is blinear interpolation.

    • InterpolationMode::kCubic, Interpolation method is bicubic interpolation.

    • InterpolationMode::kArea, Interpolation method is pixel area interpolation.

  • fill_value – [in] A vector representing the pixel intensity of the borders (default={0, 0, 0}).
