# Graph API (gapi module) {#tutorial_table_of_content_gapi}
In this section you will learn about graph-based image processing and
how G-API module can be used for that.
Merge pull request #16039 from dmatveev:dm/gapi_tutorial_interactive_face_detection * G-API-NG/Docs: Added a tutorial page on interactive face detection sample - Introduced a "--ser" option to run the pipeline serially for benchmarking purposes - Reorganized sample code to better fit the documentation; - Fixed a couple of issues (mainly typos) in the public headers * G-API-NG/Docs: Reflected meta-less compilation in new G-API tutorial * G-API-NG/Docs: Addressed review comments on Face Analytics Pipeline example

This tutorial illustrates how to build a hybrid video processing
pipeline with G-API where Deep Learning and image processing are
combined effectively to maximize the overall throughput. This
sample requires Intel® distribution of OpenVINO™ Toolkit version
2019R2 or later.

- @subpage tutorial_gapi_anisotropic_segmentation
*Languages:* C++
*Compatibility:* \> OpenCV 4.0
*Author:* Dmitry Matveev
This is an end-to-end tutorial where an existing sample algorithm
is ported on G-API, covering the basic intuition behind this
transition process, and examining benefits which a graph model
brings there.
