Abstract
U radu su razvijena tri algoritma. Prvi algoritam korišten je za segmentaciju registarske oznake s slike vozila u boji. Algoritam je podijeljen na tri glavna procesa. U prvom se procesu provodi predprocesiranje ulazne slike. Slijedi proces binarizacije Otsu metodom. Nakon uspješnog odvajanja područja interesa od ostatka slike provodi se morfološka obrada slike. Slika segmentirane registarske oznake šalje se algoritmu za segmentaciju znakova. Segmentirani znakovi spremaju se u unaprijed definirano polje, te se šalju algoritmu za optičko prepoznavanje znakova. Znakovi se prepoznavanju s obzirom na strukturne značajke znaka kao što u broj i položaj petlji u znaku. Algoritmom je postignuta uspješnost izvođenja od 90,38% uz prosječno vrijeme izvršavanja od 1,458 sekunde
Abstract (english)
This paper describes the development of three algorithms. The first algorithm is used for license plate segmentation from the color image of the vehicle. The algorithm is divided into three main processes. The first process carries out the pre-processing of the input image. The next process carries out the Threshold using the Otsu method. The last process does the morphological processing of the binary image. The segmented license plate is sent as parameter to the character segmentation algorithm. Segmented characters are saved in the pre-defined array and then sent as a parameter to the optical character recognition algorithm. The algorithm recognizes characters based on their structural features like the number and position of loops in the character. The algorithm achieves a success rate of 90,38 % with an average execution time of 1,453 seconds
