20.500.12556/DKUM-95435 Primerjava odpornosti slikovnih datotečnih formatov na okvare podatkov diplomsko delo Comparison of the robustness of image file formats against data corruption V diplomskem delu smo primerjali odpornost slikovnih formatov JPEG, JPEG2000, PNG, WebP, TIFF in HEIF ob nadzorovanih okvarah bitnega toka z namenom ugotavljanja njihovih prednosti, slabosti in zmožnosti dekodiranja. Okvare smo vnašali z metodami preklopa bitov, prepisa zlogov, zamenjave segmentov, metode "fuzzing" in krajšanjem datotek. Objektivne podobnosti med referenčnimi in okvarjenimi slikami smo merili z metrikama PSNR in SSIM. Na osnovi reprezentativnih vzorcev pri naključnih eksperimentih smo podali ugotovitve o odpornosti posameznih formatov na okvare. In this thesis, we compared the robustness of JPEG, JPEG2000, PNG, WebP, TIFF, and HEIF image file formats under controlled bitstream corruptions in order to determine their advantages, disadvantages, and decoding capabilities. We introduced errors using bit flipping, byte overwriting, segment swapping, fuzzing, and file truncation methods. We measured the objective similarities between reference and corrupted images using PSNR and SSIM metrics. Based on representative samples in random experiments, we presented findings about the robustness of individual image file formats to corruptions. slikovni datotečni formati okvare slik odpornost na okvare JPEG JPEG2000 PNG WebP TIFF HEIF PSNR SSIM image file formats image corruption robustness JPEG JPEG2000 PNG WebP TIFF HEIF PSNR SSIM true true false [Ž.
