Three-dimensional elliptic Fourier methods for the parameterization of human pinna shape

The paper describes an extension to existing work on three-dimensional elliptic Fourier descriptors (Park, K.S. and Lee, N.S., Computers and Biomedical Research, vol.20, p.125-40, 1987) which enables the efficient parameterization of the human pinna shape. The theory and implementation of the new method are discussed and examples of pinna shape parameters given. We describe an application of the method to the estimation of the acoustic pressure response of human pinnae and discuss ongoing work into the parameterization of full head shapes.
