ab: Summary: The paper described the iris image analysis and reconstruction
    procedure based on 1-D zero-crossing wavelet transform. Sharp variation
    points are among the most meaningful features for characterizing
    transient signals. As a result, The Sharp variation points can be
    detected by zero-crossing, then The sharp variation points at a few
    intermediate levels have been selected as the iris meaningful features
    for iris recognition. Mallat pointed out that the complete stable
    representation based on 1-D zero-crossing wavelet transform under
    certain restrictive assumptions, In order to compare visually the model
    to the tester’s iris image, the iris model image have to be
    reconstructed from zero-crossing wavelet transform. Accordingly, we
    translate 2-D iris image into 1-D signal as boles did. Reconstructing
    iris image, we translated the 1-D signal into 2-D image. In practice,
    we used the zero-crossing representation to complete the iris image
    analysis and reconstruction and the iris recognition system achieved a
    high efficiency.
