Abstract
Tema ovoga rada je implementacija Quite OK Image Format (QOI) algoritma u programskom jeziku Python te njegova usporedba s drugim, često korištenih algoritmima za kompresiju slike po pitanju omjera kompresije i vremena izvršavanja algoritama. QOI algoritam je algoritam za kompresiju slike bez gubitaka te kodira svaki od piksela na jedan od četiri moguća načina. Prikazana je usporedba QOI algoritma s Bzip2 i Brotli algoritmima, koji su također algoritmi za kompresiju bez gubitaka. Rezultati su pokazali kako implementacija QOI algoritma u programskom jeziku Python daje manji omjer kompresije slike te je vrijeme kodiranja i dekodiranja slike dulje.
Abstract (english)
The topic of this Master’s thesis paper is the implementation of the Quite OK Image Format (QOI) algorithm using the Python programming language and its comparison with other commonly used image compression algorithms by measuring compression ratio and algorithm execution time. The QOI algorithm is a lossless image compression algorithm that encodes each pixel in one of four possible ways. Thesis shows the comparison between the QOI algorithm and the Bzip2 and Brotli algorithms, which are also lossless compression algorithms. The results showed that the implementation of the QOI algorithm in the Python programming language yields a lower image compression ratio and longer encoding and decoding time.
