Abstract

U ovom radu istražene su mogućnosti semantičke segmentacije slika šuma s ciljem klasifikacije tipova šuma na temelju označenih podataka pet različitih tipova šuma. Za problem segmentacije s ograničenom količinom podataka ispitane su dvije različite arhitekture: U-Net i VGG16, primijenjene u nekoliko različitih konfiguracija. Testirano je treniranje s augmentiranim podatcima, kao i uspješnost modela u odnosu na broj satelitskih snimaka korištenih kao ulaz u model te broj klasa koje model... More predviđa. Najuspješnijim se pokazao model VGG16. Daljnja poboljšanja mogla bi uključivati generiranje dodatnih podataka ili korištenje kvalitetnijeg skupa podataka. Less

Abstract (english)

This paper explores the potential of semantic segmentation of forest images for the classification of forest types based on labeled data for five different forest types. For the segmentation problem with a limited amount of data, two different architectures were examined: U-Net and VGG16, applied in several different configurations. The training with augmented data was tested, along with the model's performance in relation to the number of satellite images used as input to the model... More and the number of classes the model predicts. The VGG16 model proved to be the most successful. Further improvements could include generating additional data or using a higher quality dataset.
