Labeling Experience

I worked on an image data labeling task where I annotated objects using bounding boxes for a machine learning model

I worked on an image data labeling task where I annotated objects using bounding boxes for a machine learning model. My role was to ensure accurate and consistent labels based on strict guidelines. When images were unclear or objects overlapped, I followed the rules or flagged them for review. The experience improved my attention to detail and understanding of how data quality affects model performance.
