Abstract
Cilj rada je opisati teorijske osnove kompresije slika i kompresije Huffman Coding algoritmom, a nakon toga implementirati Huffman Coding algoritam za kompresiju slika. Nakon objašnjene teorijske osnove kompresije i Huffman Coding algoritma uz primjer, kod implementiranog algoritma slijedi iste korake kao i prikazani primjer te je objašnjen istim redom. Algoritam je implementiram u Python programskom jeziku, a za dohvaćanje vrijednosti iz slike korištena je biblioteka OpenCV. Zapis u tekstualnu datoteku se odvija u dva koraka, prvo se zapisuju informacije o dimenzijama i informacije iz Huffmanovog stabla, a nakon toga slijed bitova koji nosi informacije slike i zapisan je pomoću bitarray biblioteke. Izvorna slika se može rekonstruirati iz tekstualne datoteke u koju je kompresija zapisana kao dokaz ispravne kompresije.
Abstract (english)
The aim of the paper is to describe the theoretical foundations of image compression and compression by Huffman Coding algorithm followed by the implementation of the Huffman Coding algorithm for image compression. After explaining the theoretical foundations of compression and the Huffman Coding algorithm with a simple, the implemented algorithm follows the same steps as the presented example and is explained in the same order. Algorithm is implemented in the Python programming language and the OpenCV library was used to retrieve the values from the image. Writing to the text file takes two steps, first the dimension information and information from the Huffman tree are written, followed by the bit sequence that carries the image information and is written using the bitarray library. The original image can be reconstructed from text file in which the compression is written as proof of correct compression.
