Statistical Analysis of DCT Coefficients for Ascertaining Ears Biometrics
Nisha  | Jatinder Kansal | JPS Raina
Abstract: The presented paper presents the statistical analysis of the diagonal dct coefficients of earís images in order to ascertaining the bio-metrics identity of a person. The dct coefficients matrix contains the frequency variations of earís images in three parts; the lower half of the matrix that contains the low frequency elements that make up the flashy part of the ear, the upper half that contain the high frequency elements in form of noise and diagonal elements that contain the maximum information about the features of the earís image. The diagonal elements or dct coefficients are then analyzed statistically in terms of mean deviation, standard deviation and covariance to identify the given earís image.
