In this study, we focused on detecting seat belts of drivers from camera images of the front windshield area of cars. When the color of the seat belt differs from that of the clothing worn by the driver, the seat belt can be detected by focusing on edge and pixel value differences. This study created a template representing pixel value differences and applied template matching using a genetic algorithm to achieve higher detection rates than edge-based methods. To quantitatively evaluate the performance, we created a dataset consisting of 73 images and compared the performances of each method. Notably, the proposed method achieved higher detection rates than the other methods.

The high-electromagnetic-interference (EMI)-noise area in a power circuit should be clarified when designing a low-EMI-noise power converter. For example, shielding of the power circuit prevents the EMI noise propagation to other circuits via near field couplings. It is important to know the high-EMI-noise area which should be shielded. The EMI noise distribution can be visualized by measuring the near-magnetic-field distribution above the power circuit. However, we cannot measure the near-magnetic-field distribution if there is not enough space for scanning a magnetic field probe between the power circuit and other circuits. Therefore, we propose to adopt a three-dimensional electromagnetic simulation for acquiring the near-magnetic-field distribution above a power circuit. In this paper, we study the validity of the frequency-domain noise-source model for the simulation of the near-magnetic field distribution. We evaluate the near-magnetic-field distribution maps for turn-on and turn-off of the transistor, respectively. The high-EMI-noise area differs depending on frequencies. The high-EMI-noise area for turn-on is different from that for turn-off. We have clarified that each high-EMI-noise area can be predicted by the simulation.
