Function mindspore::dataset::LFW

Function Documentation

inline std::shared_ptr<LFWDataset> mindspore::dataset::LFW(const std::string &dataset_dir, const std::string &task, const std::string &usage, const std::string &image_set, bool decode, const std::reference_wrapper<Sampler> &sampler, const std::shared_ptr<DatasetCache> &cache = nullptr)

Function to create a LFWDataset.

Note

When usage is ‘people’, the generated dataset has two columns [“image”, “label”]; When task is ‘pairs’, the generated dataset has three columns [“image1”, “image2”, “label”].

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 (default=nullptr, which means no cache is used).

Returns

Shared pointer to the LFWDataset.
