Z namenom zmanjšanja zaznave napake smo matriko algoritma za stresanje Jarvis, Judice in Ninke prilagodili s pomočjo diferencialne evolucije. Skozi optimizacijo smo spreminjali uteži v matriki tako, da smo se poskušali s stresano sliko čim bolj približati originalni sliki. Za merjenje podobnosti med dvema slikama smo uporabili metriki PSNR in SSIM. Z večkratnim zagonom optimizacije smo analizirali vpliv različnih parametrov diferencialne evolucije na kakovost končnega rezultata. Ugotovili smo, da izboljšan SSIM ne pomeni nujno boljše ujemanje stresane slike z originalno sliko. This diploma thesis deals with raster image dithering and its optimization. To minimize the perception error, we adapted the Jarvis, Judice and Ninka dithering algorithm matrix using differential evolution. Through optimization, we adjusted the weights in the matrix so that the dithered image was as similar as possible to the original image. To measure the similarity between the two images, we used the PSNR and SSIM metrics. By running the optimization multiple times, we analysed the impact of the differential evolution parameters on the quality of the result. We discovered that improved SSIM does not necessarily improve similarity between the dithered image and the original image. rastrska slika stresanje Jarvis Judice in Ninke optimizacija evolucijski algoritmi diferencialna evolucija raster image dither Jarvis Judice and Ninke optimization evolutionary algorithms differential evolution true true false [B.
