KOMPRESIJA MULTISPEKTRALNIH SATELITSKIH SNIMAKA KORIŠĆENJEM HEVC STANDARDA
Ključne reči:
HEVC, JPEG2000, kompresija, Landsat, Sentinel, multispektralne fotografije
Apstrakt
Sateliti za multispektralno snimanje Zemlje, kao što su američki Landsat 8 i evropski Sentinel-2, svakodnevno prave veliku količinu fotografija visoke rezolucije. Njihovo skladištenje zahteva veliki digitalni prostor, što uvećava cenu opreme. Landsat snima slike u nekompresovanom formatu, dok Sentinel koristi JPEG2000 kompresiju. Cilj ovog rada je da uporedi High Efficiency Video Coding (HEVC) i JPEG2000 standarde za kompresiju ovih fotografija i utvrdi da li bi HEVC bio bolje rešenje.
