Abstract
Ovaj je rad usmjeren na razvoj rješenja optičkog raspoznavanja oznaka (OMR) na ispitnim obrascima. To podrazumijeva klasifikaciju zacrnjenih kružića i optičko prepoznavanje znakova (OCR) za rukovanje ispravcima koji su pisani rukom. Objašnjeni su postupci pretprocesiranja i poravnavanja slike za obradu, segmentacije interesnih područja te detekcije relevantnih elemenata na slici. Za prepoznavanje rukom pisanih znamenki korištena je neuronska mreža trenirana na MNIST skupu podataka. Rješenje se temelji na Python programskom jeziku i koristi OpenCV za obradu slike i Keras za model neuronske mreže. Prikazani su rezultati korištenja programskog rješenja te njihova evaluacija, a na kraju je dan pregled budućeg rada i mogućih poboljšanja.
Abstract (english)
This paper focuses on the development of a solution for optical mark recognition (OMR) on test forms also known as bubble sheets. These include classification of marked bubbles and optical character recognition (OCR) to handle handwritten corrections. The paper describes procedures for preprocessing and alignment of images, segmentation of regions of interest (ROIs) and detection of relevant elements in the image. A neural network trained on the MNIST data set was used to recognize handwritten digits. The solution is based on the Python programming language and uses OpenCV for image processing and Keras for the neural network model. The results of using the software solution and their evaluation are presented, and at the end, an overview of future work and possible improvements are given.
