Please guide me. 2 Iris Recognition Sub-Problems In brief, iris recognition is a succession of operations designed to extract a binary iris code (or, more generally, a feature vector) from an eye image. The goal of this work is to provide an empirical basis for research on image segmentation and boundary detection. The iris outer boundary (limbus boundary) is present between the sclera (the white area) and the iris whereas the iris inner boundary (also known as pupil boundary) is present between the iris and the pupil (the darkest area). This scheme utilizes a predictive coding model to identify the direction of change in color and texture at each image location at a given scale, and constructs an edge flow vector. edu Abstract—The iris is the most accurate biometric to date and its localization is a vital step in any iris recognition system.
