Projects & Portfolio

Binary Segmentation for Cone Detection
Developed and trained a lightweight binary segmentation model using a simple encoder-decoder architecture to detect traffic cones in real-time for autonomous driving applications especially in the FSAE Driverless context. Achieved high accuracy and low latency, making it suitable for deployment on edge devices.

Optimized Translator Model for Jeju Dialect
Focused on developing an optimized embedding method for the Korean dialect Jejueo, leveraging jamos. Explored optimized translation by combining word identification with one-to-one mapping, aiming to facilitate the use and understanding of Jejueo and preserve the language.

Modular Mobile Robot with Computer Vision
Constructed a mobile robot capable of line tracing using computer vision (OpenCV). Hardware includes Jetson Nano, aluminum profile frame, and 9V 4A battery. Implemented PID control for motors and Kalman filter for sensor inputs. Currently integrating ROS2 and LiDAR for autonomous navigation.

VisioMed: Smart Voice-Guided Medicine Storage
Designed a smart storage system to aid visually impaired and elderly individuals. Integrates auditory reminders, NFC tags for medication ID, and computer vision to verify user actions. Powered by Raspberry Pi with magnetic and ultrasound sensors.
