Detailed Description

G-API data objects used to build G-API expressions.

These objects do not own any particular data (except compile-time associated values like with cv::GScalar) and are used to construct graphs.

Every graph in G-API starts and ends with data objects.

Once constructed and compiled, G-API operates with regular host-side data instead. Refer to the below table to find the mapping between G-API and regular data types.

G-API data type	I/O data type
cv::GMat	cv::Mat
cv::GScalar	cv::Scalar
cv::GArray<T>	std::vector<T>
cv::GOpaque<T>	T
