Abstract: This paper presents a new iris recognition method based on the statistical assessment of wavelet coefficients. For the matrix of wavelet coefficients generated by the one-dimensional wavelet multi-scale decomposition, the method presented uses statistical assessment to determine the significant wavelet coefficients at different scales and then transforms them into a binary vector to represent the iris features. The Hamming distance classifier is adopted to perform pattern matching between an input iris image and an enrolment template. The final experiments show promising results for iris recognition.

Keywords: iris recognition; pattern matching; statistical assessment; wavelet transform; wavelet coefficients; statistical assessment.
