Klasifikacija snimaka dobijenih
daljinskom detekcijom


Sinopsis:

Broj uređaja za daljinsku detekciju se neprestano povećava. Posljedica toga je da su mnogobrojne baze podataka dobijenih daljinskom detekcijom preplavljene podacima. U ovom trenutku, slike dominiraju ovim bazama podataka, kako raznovrsnošću, tako i kvantitetom. Predmet ovog istraživanja je automatska analiza slika dobijenih daljinskom detekcijom u cilju njihove klasifikacije u različite klase pokrivenosti i načina korišćenja zemljišta. Naš pristup se zasniva se na ekvivalenciji ovog problema sa problemom semantičke klasifikacije slika. Za njegovo rješavanje koristimo tehnike računarskog vida i mašinskog učenja.
