Abstract

In this paper, a new security algorithm to recognize the type of the vehicle with the vehicle image as a input image is suggested. The vehicle recognition security algorithm is composed of five core parts, such as the input image, background removal, edge areas extraction, pre-processing(binarization), and the vehicle recognition. Therefore, the final recognition rate of the security algorithm for vehicle type recognition can be affected by the function and efficiency of each step. After inputting image into a gray scale image and removing backgrounds, the binarization is performed by extracting only the edge region. After the pre-treatment process for making outlines clear, the type of vehicles is categorized into large vehicles, passenger cars and motorcycles through the ratio of height and width of the vehicle.

본 논문은 차량영상을 입력영상으로 받아 차량의 종류를 인식하는 보안 알고리즘을 연구한다. 차량 인식 보안 알고리즘은 영상입력, 배경제거, 에지영역 추출, 전처리(이진화), 차량인식 등의 5가지 핵심부분으로 구성된다. 그러므로 차량 종류 인식 보안 알고리즘의 최종 인식율은 각 단계의 역할 및 기능에 직간접적인 영향을 받는다. 영상을 그레이 스케일 이미지로 입력시킨 후 배경을 제거하고, 에지영역만 추출한 후 이진화를 거친다. 외곽선을 또렷하게 해주기 위한 전처리 과정을 거친 후 차량의 높이와 넓이의 비율을 통해 차량의 종류를 대형차, 승용차, 오토바이의 3가지 범주로 나누게 했다.
