Exploring the non-planar effects of iris deformation

We use the principles of biomechanics in order to design a biologically tenable model that explores the non-planar effects of iris deformation. Current iris biometric algorithms assume a simple transformation to approximate the planar deformation of the iris tissue. Furthermore, recent work on iris deformation only explores the planar effects of the deformation, which does not include the non-planar effects of the iris tissue caused by the thickness of the iris. Examining the non-planar effects of the iris tissue provides a more comprehensive understanding of iris deformation. The results of this work can be potentially leveraged into existing iris biometric systems.
