Abstract
Metoda potpornih vektora jedna je od najučinkovitijih za rješavanje problema prepoznavanja prometnih znakova. U ovom radu predstavljena je aplikacija za prepoznavanje znakova ograničenja brzine iz baze slike znakova. Aplikacija koristi standardni medijan i Gaussov filtar za uklanjanje šuma iz slika, Houghovu transformaciju za detekciju kružnog objekta i metodu potpornih vektora za prepoznavanje znaka. Prilikom implementacije metode potpornih vektora, bilo je potrebno klasificirati i istrenirati set slika iz baze rMASTIF. Analizom algoritma, uspostavljeni su prikladni parametri svih upotrijebljenih funkcija za postizanje optimalnih rezultata u većini slučajeva. Isto tako, prilikom detekcije pronađeni su primjeri gdje je nužno promijeniti parametre za postizanje točnih rezultata. Također, utvrđeni su primjeri iznimno loše kvalitete slike nad kojima je nemoguće obaviti detekciju. Usprkos tome, trening nad bazom uspješno je proveden te je testiranjem implementirane metode utvrđeno kako u većini slučajeva algoritam pravilno predviđa zadani prometni znak.
Abstract (english)
A support vector machine is one of the most efficient methods used for traffic sign recognition. In this paper application for speed limit traffic sign recognition from a traffic sign image database is presented. The application uses standard median filter and Gaussian filter for removing noise in corrupted images, Hough transformation for detection of a circular object within an image and a support vector machine for sign recognition. During the implementation of the support vector machine, it is necessary to classify and train a set of images taken from the rMASTIF database. While analyzing the algorithm adequate parameters are established for every function used, in order to achieve as optimal results as possible. Also, a few examples are found where changing the parameters is necessary to obtain accurate results. In addition, there are a few images in which it is impossible to detect a circle due to images’ bad quality. Despite identifying significant amount of problems, the support vector machine is successfully trained and tested. In most cases, the algorithm accurately predicting a speed sign in the tested images is established.
