Image Guidelines

FACEKI Image recommendation

Poor image quality may result in errors. Therefore, to reduce errors, note the following:

Motion blur effect can significantly increase BPCER (Bona Fide Presentation Classification Error Rate) or the rate of errors classifying a live person as a spoof.
Fish-eye lenses are not supported by FACEKI.
FACEKI does not accept any fade, blur, not clear face image, two persons in a photo, stretch dimensions, or filtered pictures.
Texture filtering can significantly increase APCER (Attack Presentation Classification Error Rate) or the errors of allowing impostors through.
Spotlights on the faces and nearest surroundings can significantly increase BPCER.
Ill-lighted environment and colored lights can significantly increase BPCER.
Appropriate distance is required to capture the face image to comply with the requirements below. Please ensure that inter-pupillary distance, face size, and recommended face proportion on the image are preserved.
The face should have proper lighting and should fit in the oval with a proper ratio and dimensions.
FACEKI does not recognize small-dimension images.
