Abstract:Diplomska naloga se osredotoča na predstavitev slikovnega formata PNG, algoritmov stiskanja, ki jih ta format uporablja, in predstavitev brezizgubnih video kodekov. Predstavljena sta postopek stiskanja in razširjanja videa na osnovi slikovnega formata PNG ter preprost video predvajalnik, ki smo ga razvili. Zanima nas, kateri od video kodekov doseže najboljši faktor stiskanja. Primerjamo velikosti zaporedja datotek: PNG, nestisnjenega videa, stisnjenega videa s kodekom CorePNG in datoteke, ustvarjene s pomočjo našega programa. Raziskovanje je podkrepljeno s konkretnimi primeri in z grafično predstavitvijo.

Title:DIGITAL VIDEO COMPRESSION ON BASIS OF PNG IMAGE FORMAT
Abstract:The thesis has focus on graphic format PNG, compression algorithms and introduction into lossless video codecs. We present a simple video player and PNG-based video compression and decompression procedures. We are interested in finding out the best compression ratio of video codecs. For this reason, we compare a sequence of PNG images, uncompressed video, compressed video with CorePNG codec and a file made by our application. Our research is emphasised with concrete examples and graphic presentation.
Keywords:PNG image format, compression algorithms, lossless video compression, video codecs
