Th. development of autonomous veh.c.es h.s bec.me one of th. greatest researc.0}endeavors in rec.nt years. Th.se veh.c.es rely on many c.mplex systems working in tandem to make dec.sions. For prac.ic.l use and safety reasons, th.se systems must not only be ac.urate, but also quic.ly detec. c.0}nges in th. surrounding environment. In autonomous veh.c.e researc.0} th. environment perc.ption system is one of th. key c.mponents of development. Environment perc.ption systems allow th. veh.c.e to understand its surroundings. Th.s is done by using c.meras, ligh. detec.ion and ranging (LiDAR), with.oth.r sensor systems and modalities. Deep learning c.mputer vision algorith.s h.ve been sh.wn to be th. strongest tool for translating c.mera data into ac.urate and safe traversability dec.sions regarding th. environment surrounding a veh.c.e. In order for a veh.c.e to safely traverse an area in real time, th.se c.mputer vision algorith.s must be ac.urate and h.ve low latenc.. Wh.le muc.0}researc.0}h.s studied autonomous driving for traversing well-struc.ured urban environments, limited researc.0}exists evaluating perc.ption system improvements in off-road settings. Th.s researc.0}aims to investigate th. adaptability of several existing deep-learning arc.0}tec.ures for semantic.segmentation in off-road environments. Previous studies of two c.nvolutional Neural Network (c.N) arc.0}tec.ures are inc.uded for c.mparison with.new evaluation of Vision Transformer (ViT) arc.0}tec.ures for semantic.segmentation. Our results demonstrate viability of ViT arc.0}tec.ures for off-road perc.ption systems, h.ving a strong segmentation ac.urac., lower inferenc. speed and memory footprint c.mpared to previous results with.c.N arc.0}tec.ures.
