Abstract

Posljednjih godina, sve se više istražuje područje računalno potpomognute medicinske dijagnostike. Za veliko poboljšanje u rezultatima problema detekcije i segmentacije, zaslužan je strelovit razvoj metoda dubokog učenja. U ovom radu fokus je na problemu segmentacije tekućina na OCT slikama mrežnice koristeći nove vrste umjetnih neuronskih mreža, kapsularne neuronske mreže. Dan je pregled dosadašnjih ostvarenja na području segmentacije OCT slika mrežnice i kapsularnih neuronskih mreža. Za... More potrebe rada, u Keras-u je implementirana relativno nova varijacija kapsularnih mreža, Matwo-CapsNet. Performanse implementacije testirane su na podskupu RETOUCH baze podataka OCT slika mrežnice. Dobiveni su vrlo dobri rezultati, mjerljivi s ponajboljim metodama koje su sudjelovale u originalnom RETOUCH izazovu. Less

Abstract (english)

In the last few years, there has been an increasing interest in the field of computer-assisted medical diagnostics. The rapid development of deep learning methods is responsible for the great improvement in the results of detection and segmentation problems. In this paper, the focus is on the segmentation of fluids on retinal OCT images using new types of artificial neural networks, capsule neural networks. Firstly, we present an overview of previous achievements in the fields of... More segmentation of OCT retinal images and capsule neural networks. Secondly, we present the implementation of a relatively new variant of capsule networks, Matwo-CapsNet, that has been implemented in Keras for the purposes of this paper. Testing was performed on the subset of RETOUCH database of OCT retinal images. Acquired results are very satisfactory, comparable to the results of best methods participating in the original RETOUCH challenge. Less
