NI Park, JW Lee, SH Lim, JS Byun, GH Na… - Forensic Science …, 2021 - Elsevier
Sounds recorded by a dashboard camera presents essential evidence on a vehicle's driving
condition for analyzing car accidents. In reality, when a direct impact of a vehicle equipped
with a dashboard camera occurs, the power supply to the dashboard camera is abruptly
terminated, and the digital video being recorded at that time may be incompletely stored;
thus, there is no information such as the location or size to be read for the image and audio
decoding. In this paper, we propose a method for recovering the linear pulse code …
