Abstract
U završnom radu opisane su temeljne operacije koje su u upotrebi pri digitalnoj obradi slika, kao i problemi koji se javljaju tijekom danog postupka. Nadalje, opisano je filtriranje slika u prostornoj domeni, uz naglasak na filtre zaglađivanja i izoštravanja te filtriranje u frekvencijskoj domeni, s naglaskom na matematičke teoreme i zakonitosti. Za poboljšanje kvalitete slika uzeto je programsko okruženje MATLAB u vidu četiriju osnovnih metoda: izjednačavanja histograma, Medijan filtra, Wiener filtra te dekorelacijskog rastezanja. Njima su tretirane jedna crno-bijela slika te tri slike u boji te je provedena analiza rezultata. Medijan filtar i Wienerov filtar su jako učinkoviti i i kod crno-bijelih i kod slika u boji, metoda dekorelacijskog rastezanja je za crno-bijele slike neupotrebljiva, dok metoda izjednačavanja histograma daje puno bolje rezultate kad se koristi za crno-bijele slike u odnosu na slike u boji.
Abstract (english)
The thesis describes the basic operations that are used in digital image processing, as well as problems that occur during a given procedure. Furthermore, image filtering in the spatial domain is described, with an emphasis on smoothing and sharpening filters, and filtering in the frequency domain, with an emphasis on mathematical theorems and regularities. To improve the image quality, the MATLAB software environment was used in the form of four basic methods: histogram equalization, Median filter, Wiener filter and decorrelation stretching. Using them, one black and white image and three color images were treated and results were analyzed. The Median filter and Wiener filter are very effective for both black and white and color images, the decorrelation stretching method is not applicable for black and white images, while the histogram equalization method gives much better results when used for black and white images compared to color images.
