Detection of Indonesian Vehicle Plate Location using Harris Corner Feature Detector Method

Abstract

Intelligent transportation systems are now starting to develop. One aspect of the intelligent transportation support system is how to recognize a vehicle. Vehicle plate recognition is an important function of this system. Plate detection systems have two problems, namely where the plate is located and how large the size is. Harris, Eigen and FAST methods have a high production value in detecting the number plate location. This is because the theoretical background is relatively focused on the angle. The Harris Corner detection system is often used because it can produce consistent values in rotating image and which has a lot of noise in an image. Morphological filters openings and closings can be seen as transformations with a structuring element which locally adapts its shape to the image structures, and therefore have lovely filtering capabilities. In this paper, we present the Indonesian plate localization based on text segmentation of unstructured standard plates with morphology filters openings and closings on pre-processing and feature detector Harris Corner method. Harris Corner method is used to detect corner points of the text, as well as using the Euclidean Distance algorithm to match features. The proposed result method produces an accuracy of 98.98%, a precision of 65.57% and a recall value of 73.55%. For further research, it needs to be compared with other methods to get the best results.

“…The implementation of research on digital images is very broad. A number of scientists use image processing to identify insect species [3]; digital images in our lives are developed to determine the location of vehicle license plates [4] [5]. This implementation of determining vehicle number plates can be used for automatic parking applications; digital images are also used for face detection in humans [6] and detection of motor vehicle license plates [7].…”
