A human ear recognition method using nonlinear curvelet feature subspace
Ear is a relatively new biometric among others. Many methods have been used for ear
recognition to improve the performance of ear recognition systems. In continuation of these
efforts, we propose a new ear recognition method based on curvelet transform. Features of
the ear are computed by applying Fast Discrete Curvelet Transform via the wrapping
technique. Feature vector of each image is composed of an approximate curvelet coefficient
and second coarsest level curvelet coefficients at eight different angles. k-NN (k-nearest …

Ear is a relatively new biometric among others. Many methods have been used for ear recognition to improve the performance of ear recognition systems. In continuation of these efforts, we propose a new ear recognition method based on curvelet transform. Features of the ear are computed by applying Fast Discrete Curvelet Transform via the wrapping technique. Feature vector of each image is composed of an approximate curvelet coefficient and second coarsest level curvelet coefficients at eight different angles. k-NN (k-nearest neighbour) is utilized as a classifier. The proposed method is experimented on two ear databases from IIT Delhi. Results achieved using the proposed method on publicly available ear database are up to 97.77% which show encouraging performance.
