标准范围

ISO/IEC 19794-5:2005规定了在人类验证和计算机自动识别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该如何出现的限制，而不是规定照片应该如何拍摄。该格式旨在指定观察者可辨别的与面部有关的可见信息，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”附录提供了有关旅行证件照片捕获和人脸识别性能与数字压缩的指导。

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.
