Labeling Experience

Data Annotator

OtherVideoBounding Box

As a data annotator at Innodata Inc., I performed frame-by-frame labeling of video content using specialized annotation tools. I was responsible for identifying, tagging, and tracking objects and events to generate high-quality training datasets for AI and machine learning projects. I ensured labels met project standards through rigorous quality assurance and review processes. • Applied bounding boxes and polygons for object tracking. • Tagged and categorized video segments with relevant metadata. • Ensured compliance with guidelines and accuracy in annotation output. • Used tools to maintain data consistency and reliability.
