Randomly perform transformations, as selected from input transform list, on the input tensor.

Public Functions

explicit UniformAugment(const std::vector<TensorTransform*> &transforms, int32_t num_ops = 2)

Constructor.

参数

  • transforms – [in] Raw pointer to vector of TensorTransform operations.

  • num_ops – [in] An integer representing the number of operations to be selected and applied.

样例
/* Define operations */
auto resize_op(new vision::Resize({30, 30}));
auto random_crop_op(new vision::RandomCrop({28, 28}));
auto center_crop_op(new vision::CenterCrop({16, 16}));
auto uniform_op(new vision::UniformAugment({random_crop_op, center_crop_op}, 2));

/* dataset is an instance of Dataset object */
dataset = dataset->Map({resize_op, uniform_op},  // operations
                       {"image"});               // input columns
explicit UniformAugment(const std::vector<std::shared_ptr<TensorTransform>> &transforms, int32_t num_ops = 2)

Constructor.

参数

  • transforms – [in] Smart pointer to vector of TensorTransform operations.

  • num_ops – [in] An integer representing the number of operations to be selected and applied.
