Summary
Conducting research on drowning accident prevention for more than 5 years using AI image analysis technology and statistical analysis, based on the experience as a lifesaver as an undergraduate student. Also, developed, implemented, maintained, and operated a system that uses AI to detect the drowning person and the rip current, which is a major cause of drowning accidents.
