Graph API

Graph API {#gapi}

Introduction {#gapi_root_intro}

OpenCV Graph API (or G-API) is a new OpenCV module targeted to make
regular image processing fast and portable. These two goals are
achieved by introducing a new graph-based model of execution.

G-API is a special module in OpenCV – in contrast with the majority
of other main modules, this one acts as a framework rather than some
specific CV algorithm. G-API provides means to define CV operations,
construct graphs (in form of expressions) using it, and finally
implement and run the operations for a particular backend.

@note G-API is a new module and now is in active development. It’s API
is volatile at the moment and there may be minor but
compatibility-breaking changes in the future.
