Labeling Experience

Traffic Sign & Vehicle Image Annotation Lead (YOLO Project)

LabelImgImageObject Detection

I participated as team leader in a YOLO-based traffic sign and vehicle recognition course project focused on AI model training. My primary responsibility was guiding the team to annotate images with traffic signs and vehicles to improve model detection accuracy. We applied object detection methodologies and iteratively refined annotations to achieve project objectives. • Managed team workflow for the annotation process. • Ensured accuracy and completeness of labeled image datasets. • Coordinated annotation rounds and model feedback cycles. • Used open-source tools (e.g., LabelImg, CVAT) for labeling tasks.
