Public Functions

PhotoTourDataset(const std::vector<char> &dataset_dir, const std::vector<char> &name, const std::vector<char> &usage, const std::shared_ptr<Sampler> &sampler, const std::shared_ptr<DatasetCache> &cache)

Constructor of PhotoTourDataset.

Parameters

• dataset_dir – [in] Path to the root directory that contains the dataset.

• name – [in] Name of the dataset to load, should be one of ‘notredame’, ‘yosemite’, ‘liberty’, ‘notredame_harris’, ‘yosemite_harris’ or ‘liberty_harris’.

• usage – [in] Part of dataset of PhotoTour, can be train or test.

• sampler – [in] Shared pointer to a sampler object used to choose samples from the dataset. If sampler is not given, a RandomSampler will be used to randomly iterate the entire dataset.

• cache – [in] Tensor cache to use.
