We present a novel method for real-time automatic license plate detection in high-resolution videos. Although there have been extensive studies of license plate detection since the 1970s, the suggested approaches resulting from such studies have difficulties in processing high-resolution imagery in real-time. Herein, we propose a novel cascade structure, the fastest classifier available, by rejecting false positives most efficiently. Furthermore, we train the classifier using the core patterns of various types of license plates, improving both the computation load and the accuracy of license plate detection. To show its superiority, our approach is compared with other state-of-the-art approaches. In addition, we collected 20,000 images including license plates from real traffic scenes for comprehensive experiments. The results show that our proposed approach significantly reduces the computational load in comparison to the other state-of-the-art approaches, with comparable performance accuracy.

For an automotive surveillance radar system, fast-chirp train based FMCW (Frequency Modulated Continuous Wave) radar is a very effective method, because clutter and moving targets are easily separated in a 2D range-velocity map. However, pedestrians with low echo signals may be masked by strong clutter in actual field. To address this problem, we proposed in the previous work a clutter cancellation and moving target indication algorithm using the coherent phase method. In the present paper, we initially composed the test set-up using a 24 GHz FMCW transceiver and a real-time data logging board in order to verify this algorithm. Next, we created two indoor test environments consisting of moving human and stationary targets. It was found that pedestrians and strong clutter could be effectively separated when the proposed method is used. We also designed and implemented these algorithms in FPGA (Field Programmable Gate Array) in order to analyze the hardware and time complexities. The results demonstrated that the complexity overhead was nearly zero compared to when the typical method was used.

Recently, interdisciplinary studies have been receiving attention. Interdisciplinary research, especially in arts and technology, is a very interesting issue. E.A.T. was founded in New York in 1966 by artists and engineers. Based on the E.A.T. case, this study analyzed the period background in which art and technology could be converged, and the characteristics of E.A.T. works. The analysis results of the period background revealed that five factors influenced the organization and development of E.A.T.. Economic factors, artistic factors, technical factors, educational factors, and sponsored cultural factors influenced the convergence of art and technology. E.A.T. works collaborated by artists and engineers generally had three characteristics. Convergence across various fields, multi-sensitivity utilizing different senses, and interaction between the environment and humans appeared in E.A.T. works. This study provides meaningful implications for both artists and engineers who wish to overcome the limitations of artistic expression and develop new technology.
