Public Functions

WIDERFaceDataset(const std::vector<char> &dataset_dir, const std::vector<char> &usage, bool decode, const std::shared_ptr<Sampler> &sampler, const std::shared_ptr<DatasetCache> &cache)

Constructor of WIDERFaceDataset.

Parameters

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

  • usage – [in] The type of data to be read, can be “train”, “test”, “valid” or “all”. “all” will read samples from “train” and “valid”.

  • decode – [in] Decode the images after reading.

  • sampler – [in] Shared pointer to a sampler object used to choose samples from the dataset.

  • cache – [in] Tensor cache to use.
