This part of ISO/IEC 19794?? specifies a record format for storing, recording, and transmitting the information from one or more facialimages within a CBEFF data structure,?? specifies scene constraints of the facial images,?? specifies photographic properties of the facial images,?? specifies digital image attributes of the facial images.Each requirement is specified for the following Face Image Types, respectively.?? Basic: This is the fundamental Face Image Type that specifies a record format including header andimage data. All Face Image Types adhere to the properties of this type. No mandatory scene,photographic and digital requirements are specified for this image type.?? Frontal: A Basic Face Image Type that adheres to additional requirements appropriate for frontal facerecognition and/or human examination. Two types of Frontal Face Image Types are defined in thisdocument, Full Frontal and Token Frontal (or simply Token).?? Full Frontal: A Face Image Type that specifies frontal images with sufficient resolution for humanexamination as well as reliable computer face recognition. This type of Face Image Type includes the fullhead with all hair in most cases, as well as neck and shoulders. This image type is suitable for permanentstorage of the face information, and it is applicable to portraits for passport, driver license, and “mugshot” images.?? Token Frontal: A Face Image Type that specifies frontal images with a specific geometric size and eyepositioning based on the width and height of the image. This image type is suitable for minimizing thestorage requirements for computer face recognition tasks such as verification while still offering vendorindependence and human verification (versus human examination which requires more detail) capabilities.
