DeepAffex™ Extraction Library

The DeepAffex™ Extraction Library is a low-level library used to extract facial blood-flow information from a sequence of face-tracked images using a technology called Transdermal Optical Imaging™. It is available on three desktop platforms (Windows, macOS and Linux) and can be downloaded from the DeepAffex™ website. It has bindings to several popular programming languages made possible by its C API which facilitates linking with C Foreign Function Interfaces.

The library is canonically documented in the C/C++ documentation.

Mobile and Web

On iOS and Android, blood-flow extraction is managed by the higher-level Anura Core SDK. On the web, it's managed by the the Web Measurement Service.
