Kvantitativna primerjava učinkovitosti kodiranja videa po standardih H.264 in H.265

TURKOVIĆ, KLEMEN (author), Burnik, Urban (mentor)

Diplomsko delo opisuje kvantitativno primerjavo kvalitete kodiranja kodekov H.264/AVC ter H.265/HEVC. Na osnovi metodologije PSNR ter SSIM za merjenje kakovosti videa želim pokazati napredek in učinkovitosti novega kodirnega standarda H.265/HEVC. V uvodnem delu so predstavljeni cilji zaključne naloge in orodja, ki sem jih uporabil za izvedbo diplomske naloge. V drugem delu sledi razlaga delovanja kodekov H.264/AVC in H.265/HEVC, ki sem ju primerjal. Sledi del, kjer je opisan postopek za primerjavo učinkovitosti obeh kodirnih postopkov na osnovi metodologij PSNR ter SSIM in odprtokodnih programskih paketov za kodiranje in dekodiranje videa, s pomočjo katerih sem pridobil potrebne podatke za primerjalno analizo. V zadnjem poglavju so prikazani rezultati primerjave kodeka H.264/AVC in H.265/HEVC na naboru dvanajstih značilnih video posnetkov.

Abstract

The thesis describes a quantitative comparison of the encoding quality of H.264/AVC and H.265/HEVC codecs. Based on PSNR and SSIM methodology for video quality measurement, I want to show the progress and effectiveness of the new H.265/HEVC coding standard. The introductory part presents the objectives of the final thesis and tools that I used to complete my thesis. The second part explains the operation of compared H.264/AVC and H.265/HEVC codecs. The third part describes a procedure for comparing the quality of performace of both coding procedures based on PSNR and SSIM methodologies and open source video encoding and decoding software packages, trough which I obtained the necessary data for benchmarking. The last section shows the result of comparing H.264/AVC and H.265/HEVC codecs on a set of twelve typical videos.
