Abstract EN
Internet services that share vehicle black box videos need a way to obfuscate license plates in uploaded videos because of privacy issues.
Thus, plate detection is one of the critical functions that such services rely on.
Even though various types of detection methods are available, they are not suitable for black box videos because no assumption about size, number of plates, and lighting conditions can be made.
We propose a method to detect Korean vehicle plates from black box videos.
It works in two stages: the first stage aims to locate a set of candidate plate regions and the second stage identifies only actual plates from candidates by using a support vector machine classifier.
The first stage consists of five sequential substeps.
At first, it produces candidate regions by combining single character areas and then eliminates candidate regions that fail to meet plate conditions through the remaining substeps.
For the second stage, we propose a feature vector that captures the characteristics of plates in texture and color.
For performance evaluation, we compiled our dataset which contains 2,627 positive and negative images.
The evaluation results show that the proposed method improves accuracy and sensitivity by at least 5% and is 30 times faster compared with an existing method.
