Iris Indexing Techniques: A Review

Abstract: The objective of this paper is to present the state of art in iris indexing. The potential raise of accurateness along with enhanced robustness beside forgeries makes in fact iris recognition a promising field for research. The performance of a biometric system is evaluated based on the retrieval time and error rate which are dependent on the size of the database and hence the need for indexing. Iris indexing can be categorized based on the texture analysis, color and SFIT key point. Further the paper discusse… Show more

“…We used 450 images (225 ocular images of the left eye and 225 ocular images of the right eye, respectively) of 320x240 pixels size. These images belong to the Multimedia University database (MMU1) 1 , which is a public eye image database for iris-based biometrics training models. The experiment was performed in MATLAB R2018a (the MathWorks, Natick, MA, USA).…”

“…The textural characteristics of the iris provide unique high-density information that explains why iris recognition is considered the most reliable and accurate biometric identification system available [1]. Omran et al [2] presented an efficient structure for the iris recognition system called IRISNet.…”

“…This is because the codes (templates) generated for comparison are multidimensional data, and methods for specific access domain are needed. Related to the last point, the implementation of the extension is intended to include indexing methods based on IrisCode [7,8,21], in order to allow simple and efficient data management, even for large volumes of data.…”

“…Since biometrics-based identification systems, especially iris, work with high dimensional characteristics; extensive searching in a large database increases response time. One strategy to improve this aspect is to use indexing techniques [8], as this reduces the search space for an identification system by quickly choosing a subset of iris images from the database in order to determine a possible match. In this sense, it is important for the extension to provide domain indexes associated with identification methods.…”

“…The iris is a thin circular ring-shaped region positioned between the black pupil and the white sclera of the human eye. It is responsible for the amount of light reaching the retina by controlling the diameter of the pupil [1]. Essentially it consists of randomly generated characteristics that results in very complex and temporally constant patterns.…”
