Typedef Documentation

IEConfig

using cv::gapi::ie::IEConfig = typedef std::map<std::string, std::string>

Enumeration Type Documentation

TraitAs

enum cv::gapi::ie::TraitAs : int

strong

Specifies how G-API and IE should trait input data

In OpenCV, the same cv::Mat is used to represent both image and tensor data. Sometimes those are hardly distinguishable, so this extra parameter is used to give G-API a hint.

This hint controls how G-API reinterprets the data when converting it to IE Blob format (and which layout/etc is assigned to this data).

Enumerator
TENSOR	G-API traits an associated cv::Mat as a raw tensor and passes dimensions as-is.
IMAGE	G-API traits an associated cv::Mat as an image so creates an "image" blob (NCHW/NHWC, etc)
