One of the neural network algorithms that can be used in iris recognition is self-organizing map (SOM). This algorithm has a
weakness in determining the initial weight of the network, which is generally carried out randomly, which can result in a
decrease in accuracy when an incorrect determination is made. The solution that is often used is to apply a hybrid process in
determining the initial weight of the SOM network. This study takes an approach using the cosine similarity equation to
determine the initial weight of the network SOM in order to increase recognition accuracy. In addition, the localization process
needs to be carried out to limit the area of the iris image being studied so that it is easy for the recognition process to be carried
out. The method proposed in this study for iris recognition, namely hybrid SOM and Daugman’s algorithm, has been tested on
several people by capturing the iris of the eye using a digital camera. The captured eyes have been localized first using the
Daugman’s algorithm, and then the image features were extracted using the GLCM and LBP methods. In the final stage of the
study, an iris recognition comparison test was performed, and the results obtained an accuracy of 85.50% using the proposed
method and an accuracy of 73.50% without performing a hybrid process on the SOM network.
