Impact of Occlusion Masks on Gender Classification from Iris Texture

Figure 3

Mask pairing example. Masks with different shapes were used to better illustrate the process. (a) Masks from different-gendered iris are paired. The masks are shown in red and blue. These masks should be similar in order to reduce the information that is lost. (b) The OR operation is performed on both masks generating a paired mask, which is shown in yellow. (c) The new mask is applied to the iris.
