Abstract
Standardni medijan filter poznat je kao učinkovito riješenje problema uklanjanja šumova iz slika, međutim kada se radi o slikama koje su teže oštećene šumma, standardni medijan filter gubi na učinkovitosti. U ovom je radu napravljen program za uklanjanje impulsnog sol i papar šuma primjenom medijan filtra, adaptivog medijan filtra i adaptivog medijan filtra s BDND algoritmom. Analizirana je kvaliteta slika nakon uklanjanja impulsnog šuma navedenim algoritmima te je utvrđeno da adaptivni medijan filtar učinkovito otklanja šum u slikama s manje detalja i s izraženim rubovima. Za slike s mnoštvom detalja najbolje rezultate pokazuje adaptivni medijan filtar s BDND algoritmom, ali ovaj način otklanjanja šuma zahtjeva značajno više procesorskog vremena i nije pogodan kod visokih postotaka šumom oštećenih elemenata slike.
Abstract (english)
Standard median filter is known as an effective solution in noise removing from corrupted images, however when it comes to badly corrupted images standard median filter loses its effectiveness. In this paper a program has been made to remove salt and pepper noise by applying a median filter, adaptive median filter and adaptive median filter with BDND algorithm. Quality of the image has been analyzed after removing the impulse noise using mentioned algorithms and found that adaptive median filter effectively eliminates noise in images with less details and with pronounced edges. For pictures with lot of details best results shows adaptive median filter with BDND algorithm, but this method of eliminating noise requires significantly more processing time and is not suitable for the large percentage of damaged picture elements
