ISO/IEC NP 25447 Face image profile for less constrained capture conditions

Scope

Requirements, recommendations, and best practices in face data acquisition for less constraint applications.

Purpose

To enable face recognition in less demanding, more cost-sensitive use cases, we propose the development of a new face image profile accompanying those in ISO/IEC 30794-5:2019 Annex D. The new profile would allow capture conditions that are more relaxed than those in the existing Annex D.2 of this standard. The profile is primarily geared towards non-governmental applications in retail, finance, travel, health care, and physical/logical access. Therefore, they do not explicitly support manual face adjudication. In the initial working draft, we specify relaxed requirements for spatial sampling, head pose, illumination, and exposure. The proposed new thresholds are informed by what several face vendors consider adequate for achieving very good face recognition performance using their latest algorithms. We adopt all other requirements and recommendations from ISO/IEC 39794-5:2019 Annex D.2 but encourage experts to propose adjusted values for those requirements as well if appropriate. Some modifications may need to be substantiated empirically during the development of this document. Also see Annex P below.
