`findface-sf-api`¶

The findface-sf-api service implements HTTP API for the FindFace core main functionality such as face detection and face recognition (the mentioned functions themselves are provided by findface-extraction-api`). It interfaces with the biometric database powered by Tarantool via the findface-tarantool-server service, as well as with findface-extraction-api (provides face detection and face recognition) and findface-upload (provides a storage for original images and FindFace core artifacts).

To detect a face in an image, you need to send the image in an API request to findface-sf-api. The findface-sf-api will then redirect the request to findface-extraction-api for face detection and recognition.

If there is a configured video face detection module in the system (like in FindFace Security), findface-sf-api also interfaces with the findface-facerouter service. It receives data of detected in video faces along with processing directives from findface-facerouter, and then executes the received directives, for example, saves faces into a specific database gallery.

Note

In FindFace Security, findface-facerouter functions are performed by findface-security.

Functionality:

HTTP API implementation (face detection and face recognition methods, performed via findface-extraction-api).
saving face data to the biometric database (performed via findface-tarantool-server),
saving original images, face thumbnails and normalized face images to an NginX-powered web server (via findface-upload).
provides interaction between all the FindFace core components.

The findface-sf-api configuration is done through the /etc/findface-sf-api.ini configuration file.

When configuring findface-sf-api, refer to the following parameters:

Parameter	Description
`extraction-api` -> `extraction-api`	IP address of the `findface-extraction-api` host.
`storage-api` -> `shards` -> `master`	IP address of the `findface-tarantool-server` master shard.
`storage-api` -> `shards` -> `slave`	IP address of the `findface-tarantool-server` replica shard.
`limits` -> `body-image-length`	The maximum size of an image in an API request, bytes.
`upload_url`	WebDAV NginX path to send original images, thumbnails and normalized face images to the `findface-upload` service.
