Abstract
The iris, considered as part of ocular biometrics, is an externally visible, yet protected organ whose unique epigenetic pattern remains stable throughout adult life. This characteristic makes it a very important modality for use as a biometric for authentication. When a subject wishes to be identified by iris recognition system, their eyes are first photographed, and then a template is created. This template is then compared with the other templates stored in a database until a correct match is found or it remains unidentified. Steady Illumination color Local Ternary Pattern (SIcLTP) has been used as a feature extractor in this paper to extract unique information from the color irises. The image matching is done using zero-mean sum of squared differences between the two equally sized images. The result shows that it can outperform the conventional local binary pattern as a texture descriptor.
