Constructor & Destructor Documentation

mic::importers::MNISTPatchImporter::MNISTPatchImporter ( std::string node_name_ = "mnist_patch_importer" )

Constructor. Sets MNIST image default properties. Registers properties.

Parameters

node_name_ Name of the node in configuration file.

Definition at line 32 of file MNISTPatchImporter.cpp.

References data_filename, image_height, image_width, labels_filename, patch_size, and samples_limit.

virtual mic::importers::MNISTPatchImporter::~MNISTPatchImporter ( )

inlinevirtual

Virtual destructor. Empty.

Definition at line 47 of file MNISTPatchImporter.hpp.

Member Function Documentation

size_t mic::importers::MNISTPatchImporter::getPatchSize ( )

inline

Returns the patch size.

Definition at line 79 of file MNISTPatchImporter.hpp.

References patch_size.

bool mic::importers::MNISTPatchImporter::importData ( )

virtual
