Abstract:V magistrskem delu sta opisani zasnovi dveh pristopov strojnega učenja za razpoznavo značilnosti v človeškem očesu na podlagi majhne učne množice. Implementirani sta dve tehniki; semantična segmentacija in lokalizacija. Obe rešitvi delujeta na osnovi konvolucijskih nevronskih mrež in iz digitalnih fotografij očes razpoznata položaj zenice, zunanjo obrobo šarenice ter barvo le-te. Problem omejene učne množice smo naslovili z uporabo več tehnik obogatitve učne množice na podlagi obstoječih učnih podatkov. Najboljše rezultate je dosegla segmentacijska nevronska mreža, tehnike obogatitve učne množice pa so se izkazale za nepogrešljive pri učenju na majhni učni množici.

Title:Automatic detection of eye features using machine learning with a small dataset
Abstract:In this master's thesis we designed two different machine learning approaches for detection of eye features based on a small training dataset. Implemented and described are two solutions; semantic segmentation and localization. Both are based on convolutional neural networks, and are able to detect iris position, iris contour and it's color from digital images. We addressed the problem of a limited training dataset with multiple augmentation techniques, which work with existing data. The best results were achieved with semantic segmentation approach. Data augmentation techniques proved to be an essential tool when working with a limited data set.
Keywords:convolutional neural networks, semantic segmentation, localization, dataset expansion
