Getting started with the SDK libraries

Are you a developer who is excited about the opportunity of accessing the DeepAffex engine but unsure how to begin this process? Outlined here you will find a brief step-by-step description to assist you to immediately get started on this rewarding journey!

DFX "Software Development Kit" (SDK) Overview

The primary purpose of the SDK is to convert an incoming stream of face-tracked image data into resultant blood-flow. This procedure is referred to as the blood-flow extraction and is an important stage in the TOI “front-end” pipeline functionality required for DeepAffex processing. Through configuration, the SDK is used to generate measurement data (binary payloads) sequences that are then forwarded to DeepAffex for analysis and processing.

As noted elsewhere the SDK provides extraction of the subjects facial blood-flow information from the incoming video frames. The client application is responsible for supplying video frames with accurate timestamps (e.g. from a digital camera or video file), detecting faces in the video frames and annotating them with "MPEG-4 facial animation points" (a standard naming convention for face point labeling provided by many 3rd party off-the-shelf face-detection libraries e.g. dlib, Visage etc.).

DeepAffex SDK

The DeepAffex SDK exists as proprietary source-code and is written in C. NuraLogix distributes SDK binaries that are compatible with Ubuntu, macOS and Windows operating platforms. We also provide the source files for a C++ wrapper in the SDK. All client applications using the C++ binding will require linking against OpenCV cv::Mat structures. The underlying C library headers have no external dependencies.

DeepAffex™ SDK Python wrappers for Windows, Linux and macOS are now available to download as wheels. A JavaScript binding (based on webasm) is currently in development. Other language bindings and operating systems are possible on request.
