Performance analysis of a hyperspectral system for human iris imaging

Hyperspectral images of the human iris, containing spectral and spatial information of the iris, are acquired by a custom developed instrument. We developed this instrument specifically to perform in-vivo spectral reflectance measurements of the human iris. The significance of the data cube acquired is strictly related to the acquisition system performance. This paper analyzes the qualitative and quantitative in-vivo performances of our instrument considering in-vivo repeatability tests and comparing left and right irises of normal subjects, without visually assessed heterochromia of the irises.
