class CocoDataset : public mindspore::dataset::Dataset
A source dataset for reading and parsing Coco dataset.
Public Functions
-
CocoDataset(const std::vector<char> &dataset_dir, const std::vector<char> &annotation_file, const std::vector<char> &task, const bool &decode, const std::shared_ptr<Sampler> &sampler, const std::shared_ptr<DatasetCache> &cache, const bool &extra_metadata)
Constructor of CocoDataset.
- Parameters
dataset_dir – [in] Path to the root directory that contains the dataset.
annotation_file – [in] Path to the annotation json.
task – [in] Set the task type of reading coco data, now support ‘Detection’/’Stuff’/’Panoptic’/’Keypoint’.
decode – [in] Decode the images after reading.
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 (default = RandomSampler()).cache – [in] Tensor cache to use (default=nullptr which means no cache is used).
extra_metadata – [in] Flag to add extra meta-data to row. (default=false).
