Member Function Documentation

◆ readDescriptorMap()

static bool Ocean::Tracking::MapBuilding::Utilities::readDescriptorMap	(	IO::InputBitstream &	inputStream,
		std::shared_ptr< UnifiedDescriptorMap > &	unifiedDescriptorMap
	)

static

Reads a descriptor map from an output stream.

Parameters

inputStream	The stream from which the map will be read
unifiedDescriptorMap	The resulting descriptor map

Returns: True, if succeeded

◆ writeDescriptorMap()

static bool Ocean::Tracking::MapBuilding::Utilities::writeDescriptorMap	(	const UnifiedDescriptorMap &	unifiedDescriptorMap,
		IO::OutputBitstream &	outputStream
	)

static
