08 Output Image IMAGE_TYPE_CROPPED_AND_MASKED with JPEG2000 compression; needs to comply with the ISO standard for Iris Image Record (IIR) i.e.ISO/IEC: 197946:2011, Section 6.1, 6.4.
09 Contrast The iris image should have good grey level separation between the iris and sclera and between the iris and pupil and should have sufficientcontrast to reveal the iris texture.
10 Optical Distortion The iris image should not exhibit effects of optical distortion including spherical aberration, chromaticaberration, astigmatism and coma consistent with standard optical design practices
