标准范围
ISO/IEC 19794-6:20 11规定了用于生物特征登记、验证和识别系统的虹膜图像交换格式。图像信息可以存储为可选地用ISO/IEC 15948或ISO/IEC 15444压缩的强度值的阵列,或者可选地用ISO/IEC 15948或ISO/IEC 15444压缩的强度值的阵列,其可以在虹膜周围裁剪,虹膜在中心,并且可以结合非虹膜区域的感兴趣区域掩蔽。ISO/IEC 19794-6:20 11没有建立对相机的光学规格的要求、对虹膜图像的光度特性的要求或对虹膜设备的注册过程、工作流程和使用的要求。
ISO/IEC 19794-6:2011 specifies iris image interchange formats for biometric enrolment, verification and identification systems. The image information might be stored as
- an array of intensity values optionally compressed with ISO/IEC 15948 or ISO/IEC 15444, or
- an array of intensity values optionally compressed with ISO/IEC 15948 or ISO/IEC 15444 that might be cropped around the iris, with the iris at the centre, and which might incorporate region-of-interest masking of non-iris regions.
ISO/IEC 19794-6:2011 does not establish
- requirements on the optical specifications of cameras,
- requirements on photometric properties of iris images, or
- requirements on enrolment processes, workflow and use of iris equipment.
