ISO/IEC 19794-5:2005规定了在人类验证和计算机自动识别环境中使用的人脸图像的场景、摄影、数字化和格式要求。在这种格式中指定场景和摄影要求的方法是仔细描述照片应如何显示的约束，而不是规定照片应如何拍摄。该格式的设计允许观察者识别与人脸有关的可见信息，如性别、姿势和眼睛颜色。 数字图像格式可以是ISO标准JPEG或JPEG2000。最后，“最佳实践”附录提供了旅行证件照片捕获和人脸识别性能与数字压缩的对比指南。 本ISO/IEC 19794-5:2005的合并再版包含ISO/IEC 19794-5:2005的原始内容，并纳入了ISO/IEC 19794-5:2005/Amd 1:2007和ISO/IEC 19794-5:2005/Amd 2:2009的修正案和技术勘误表ISO/IEC 19794-5:2005/Cor 1:2008、ISO/IEC 19794-5:2005/Cor 2:2008、ISO/IEC 19794-5:2005/Cor 3: 2013年，ISO/IEC 19794-5:2005/Cor 4:2015，以及未发布的ISO/IEC 19794-5:2005/Cor 5草案。

ISO/IEC 19794-5:2005 specifies scene, photographic, digitization and format requirements for images of faces to be used in the context of both human verification and computer automated recognition. The approach to specifying scene and photographic requirements in this format is to carefully describe constraints on how a photograph should appear rather than to dictate how the photograph should be taken. The format is designed to allow for the specification of visible information discernable by an observer pertaining to the face, such as gender, pose and eye colour. The digital image format can be either ISO standard JPEG or JPEG2000. Finally, the 'best practice' appendices provide guidance on photo capture for travel documents and face recognition performance versus digital compression.
