Detailed Description

BufferPool for use with CUDA streams.

BufferPool utilizes cuda::Stream's allocator to create new buffers. It is particularly useful when BufferPoolUsage is set to true, or a custom allocator is specified for the cuda::Stream, and you want to implement your own stream based functions utilizing the same underlying GPU memory management.

Constructor & Destructor Documentation

◆ BufferPool()

cv::cuda::BufferPool::BufferPool ( Stream & stream )

explicit

Gets the BufferPool for the given stream.

Member Function Documentation

◆ getAllocator()

Ptr<GpuMat::Allocator> cv::cuda::BufferPool::getAllocator ( ) const

inline

Returns the allocator associated with the stream.

◆ getBuffer() [1/2]

GpuMat cv::cuda::BufferPool::getBuffer	(	int	rows,
		int	cols,
		int	type
	)

Allocates a new GpuMat of given size and type.

◆ getBuffer() [2/2]

GpuMat cv::cuda::BufferPool::getBuffer	(	Size	size,
		int	type
	)
