Abstract
Cilj rada je proučiti postojeće metode i formate koji se koriste za kompresiju slika bez gubitaka podataka uz korištenje Huffmanovog kodera, te predložiti novi algoritam za istu. Predloženi algoritam temelji se na arbitrarnom obliasku piksela u slici i baziran je na A* algoritmu, te je implementiran u programskom jeziku Python 3. Stopa kompresije opisanog algoritma je u prosjeku 0 - 10 % bolja u odnosu na format PNG i ovisi o karakteristikama slike kao što su količina finih detalja i šuma u slici.
Abstract (english)
The goal of the paper is to investigate methods and formats used for lossless image compression based on Huffman coding, and to propose a new approach to the aforementioned problem. The proposed algorithm, based on arbitrary order of pixel traversal, is built on top of the A* algorithm and is implemented in Python 3 programming language. The proposed algorithm has compression rate that is on average 0-10% better than the PNG equivalent and depends on image characteristics such as detail and noise levels.
