Abstract
U okviru rada predstavljeni su različiti pristupi za segmentaciju slike, uključujući tradicionalne algoritme, konvolucijske modele za semantičku segmentaciju i modele zasnovane na pažnji. Detaljno je opisana arhitektura odabranih modela: Transformer, Vision Transformer, Data-efficient Image Transformer i Segmenter. Kako bi se ublažila potreba za velikom količinom slika označenih na razini piksela, istražene su različite metode polunadziranog učenja s naglaskom na metode konzistencijskog učenja. Implementirana je metoda polunadziranog učenja temeljena na modelu učenik-učitelj uz fotometrijske perturbacije i upotrebu maskirajućeg autoenkodera te je iskorištena za učenje modela Segmenter na javno dostupnom skupu podataka CityScapes.
Abstract (english)
This thesis describes different image segmentation techniques, including traditional ad-hoc algorithms and machine learning approaches: convolutional and attention-based models. We described and explained the architecture of the following models: Transformer, Vision Transformer, Data-efficient Image Transformer and Segmenter. Semi-supervised training is utilized to tackle the problematic need for a large amount of pixel-wise labeled data in the context of semantic segmentation. Focus is placed on consistency regularization methods. We implemented a semi-supervised training procedure based on the student-teacher model with the use of photometric perturbations and token masking, and used it for training of the Segmenter model on the publicly available CityScapes dataset.
