class VOCDataset : public mindspore::dataset::Dataset
A source dataset for reading and parsing VOC dataset.
Public Functions
-
VOCDataset(const std::vector<char> &dataset_dir, const std::vector<char> &task, const std::vector<char> &usage, const std::map<std::vector<char>, int32_t> &class_indexing, bool decode, const std::shared_ptr<Sampler> &sampler, const std::shared_ptr<DatasetCache> &cache, bool extra_metadata)
Constructor of VOCDataset.
- Parameters
dataset_dir – [in] Path to the root directory that contains the dataset.
task – [in] Set the task type of reading voc data, now only support “Segmentation” or “Detection”.
usage – [in] The type of data list text file to be read (default = “train”).
class_indexing – [in] A str-to-int mapping from label name to index, only valid in “Detection” task.
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).
