class LFWDataset : public mindspore::dataset::Dataset

A source dataset for reading and parsing LFW dataset.

Public Functions

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

Constructor of LFWDataset.

Parameters

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

  • task – [in] Set the task type of reading LFW, support “people” and “pairs”.

  • usage – [in] The image split to use, support “10fold”, “train”, “test” and “all”.

  • image_set – [in] Image set of image funneling to use, support “original”, “funneled” and “deepfunneled”.

  • 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.
