Template Parameters

A	network type defined with G_API_NET() macro.

Parameters

roi	a list of rectangles describing regions of interest in the source image. Usually an output of object detector or tracker.
args	network's input parameters as specified in G_API_NET() macro. NOTE: verified to work reliably with 1-input topologies only.

Returns: a list of objects of return type as defined in G_API_NET(). If a network has multiple return values (defined with a tuple), a tuple of GArray<> objects is returned with the appropriate types inside.

Parameters

image	A source image containing regions of interest
args	GArray<> objects of cv::Rect or cv::GMat, one per every network input: If a cv::GArray<cv::Rect> is passed, the appropriate regions are taken from `image` and preprocessed to this particular network input; If a cv::GArray<cv::GMat> is passed, the underlying data traited as tensor (no automatic preprocessing happen).

Returns: a list of objects of return type as defined in G_API_NET(). If a network has multiple return values (defined with a tuple), a tuple of GArray<> objects is returned with the appropriate types inside.

◆ island()

void cv::gapi::island	(	const std::string &	name,
		GProtoInputArgs &&	ins,
		GProtoOutputArgs &&	outs
	)

Define an tagged island (subgraph) within a computation.

Declare an Island tagged with name and defined from ins to outs (exclusively, as ins/outs are data objects, and regioning is done on operations level). Throws if any operation between ins and outs are already assigned to another island.

Islands allow to partition graph into subgraphs, fine-tuning the way it is scheduled by the underlying executor.

Parameters

name	name of the Island to create
ins	vector of input data objects where the subgraph begins
outs	vector of output data objects where the subgraph ends.

The way how an island is defined is similar to how cv::GComputation is defined on input/output data objects. Same rules apply here as well – if there's no functional dependency between inputs and outputs or there's not enough input data objects were specified to properly calculate all outputs, an exception is thrown.

Use cv::GIn() / cv::GOut() to specify input/output vectors.
