Abstract

U ovom radu opisan je problem očitavanja rukom pisanih studentskih matičnih brojeva. U radu je opisan cijeli postupak analize skeniranog rukom pisanog matičnog broja, od predobrade slike, preko odvajanja znamenki pa sve do prepoznavanja odvojenih znamenki. Predobrada je napravljena korištenjem algoritama binarizacije (prvenstveno Otsuovom metodom) i stanjivanja (Zhang-Suenovim algoritmom). Susjedne znamenke odvojene su algoritmom projekcija vertikalnih histograma. Prepoznavanje znamenaka... More obavljeno je pomoću algoritama strojnog učenja, točnije umjetnom neuronskom mrežom. Naposljetku su dani prijedlozi za daljnji rad i poboljšanja rada na problemu. Less

Abstract (english)

This paper describes the problem of automatic recognition of handwritten student identifiers. All steps in solving the problem were presented: image preprocessing, digit segmentation and digit recognition. We used binarization (primarily Otsu's method) and thinning (Zhang-Suen thinning) algorithms for image preprocessing. Adjacent digits were split using vertical histogram projection algorithm. Artificial neural network was used for digit recognition (classification). Finally,... More suggestions for further work on the project were given. Less
