Detailed Description

Function Documentation

void cv::cuda::createContinuous	(	int	rows,
		int	cols,
		int	type,
		OutputArray	arr
	)

Creates a continuous matrix.

Parameters

rows	Row count.
cols	Column count.
type	Type of the matrix.
arr	Destination matrix. This parameter changes only if it has a proper type and area ( \(\texttt{rows} \times \texttt{cols}\) ).

Matrix is called continuous if its elements are stored continuously, that is, without gaps at the end of each row.

void cv::cuda::ensureSizeIsEnough	(	int	rows,
		int	cols,
		int	type,
		OutputArray	arr
	)

Ensures that the size of a matrix is big enough and the matrix has a proper type.

Parameters

rows	Minimum desired number of rows.
cols	Minimum desired number of columns.
type	Desired matrix type.
arr	Destination matrix.

The function does not reallocate memory if the matrix has proper attributes already.

void cv::cuda::registerPageLocked ( Mat & m )

Page-locks the memory of matrix and maps it for the device(s).

Parameters

m	Input matrix.

void cv::cuda::setBufferPoolConfig	(	int	deviceId,
		size_t	stackSize,
		int	stackCount
	)

void cv::cuda::setBufferPoolUsage ( bool on )

BufferPool management (must be called before Stream creation)

void cv::cuda::unregisterPageLocked ( Mat & m )

Unmaps the memory of matrix and makes it pageable again.

Parameters

m	Input matrix.
