| Abstract: | V diplomskem delu smo se ukvarjali z algoritmi steganografije v rastrskih slikah. Opisali in implementirali smo metodo najmanj pomembnega bita, histogramsko metodo, metodo cik-cak, robno metodo in metodo spremembe stopnje sivine. Merili smo količino podatkov, ki jih lahko skrijemo, ne da bi izgled slike opazno spremenili. Za primerjavo originalne in stegoslike smo uporabili metriki PSNR in SSIM. Ob upoštevanju količine podatkov in popačenosti slike je najboljša metoda najmanj pomembnega bita z dvema bitoma, kot najslabša metoda pa se je izkazala metoda najmanj pomembnega bita s štirimi biti. |
