構築子と解体子

BackendWrapper() [1/2]

cv::dnn::BackendWrapper::BackendWrapper	(	int	targetId,
		const cv::Mat &	m
	)

Wrap cv::Mat for specific backend and target.

引数

[in]	targetId	Target identifier.
[in]	m	cv::Mat for wrapping.

Make CPU->GPU data transfer if it's require for the target.

BackendWrapper() [2/2]

cv::dnn::BackendWrapper::BackendWrapper	(	const Ptr< BackendWrapper > &	base,
		const MatShape &	shape
	)

Make wrapper for reused cv::Mat.

引数

[in]	base	Wrapper of cv::Mat that will be reused.
[in]	shape	Specific shape.

Initialize wrapper from another one. It'll wrap the same host CPU memory and mustn't allocate memory on device(i.e. GPU). It might has different shape. Use in case of CPU memory reusing for reuse associated memory on device too.
