Abstract
Cilj ovog diplomskog rada bio je implementirati U-Net, SegNet i ENet arhitekture te njihov trening uz pomoć PyTorch biblioteke, a dobivene rezultate koristiti za usporedbu navedenih arhitektura po pitanju točnosti, brzini izvođenja, učinkovitosti u stvarnom vremenu i kompleksnosti implementacije. Trening je proveden na Cityscapes skupu podataka, na kojem je provedena pred-obrada potrebna za korištenje pri treningu. Prije treninga, arhitekture su uspoređene po veličini i broju parametara; tijekom treninga, prate se srednja vrijednost unije i presjeka te točnost piksela; a nakon treninga uspoređuju se po trajanju i brzini treniranja, broju epoha te se provodi testiranje na testnom dijelu skupa podataka. Pri testiranju se mjere vrijeme zaključivanja i mogućnost izvođenja u stvarnom vremenu, a točnost se mjeri kvalitativno, pošto ne postoji izvor istine za segmentacije testnog skupa. Navedenim usporedbama pružen je dubok uvid u primjenjivost navedenih arhitektura u kontekstu automobilske percepcije te je svakoj arhitekturi pronađena prikladna primjena na temelju njezinih rezultata i performansi – ENet je izabrana za zadatke u kojima su ključne brzina i učinkovitost resursa, a U-Net i SegNet se, zbog svojih sličnih rezultata, predlažu za istu primjenu, a to su situacije u kojima je točnost bitnija od iskorištenosti resursa.
Abstract (english)
The aim of this thesis was to implement U-Net, SegNet and ENet architectures along with their training with the help of the PyTorch library, and using the obtained results to compare the mentioned architectures in terms of accuracy, execution speed, real-time efficiency and implementation complexity. The training was carried out on the Cityscapes dataset, which was pre-processed for use in training. Before the training, the architectures were compared according to their size and number of parameters; during the training the mean Intersection over Union and the pixel accuracy were monitored; after the training, they were compared according to the duration and speed of the training, the number of epochs, and testing was carried out on the test part of the data set. During testing, inference time and real-time-execution capabilities were measured quantitatively, and accuracy was measured qualitatively, since there is no ground truth for the test set segmentations. The aforementioned comparisons provided deep insight into the applicability of the architectures in the context of automotive perception, and a suitable task was found for each architecture based on its results and performance - ENet was chosen for tasks where speed and resource efficiency are key, while U-Net and SegNet are suggested for the same tasks due to their similar results – tasks in which the accuracy is more important than resource utilization.
