Labeling Experience

Data Annotation & Atomic Action Labeling Contributor | Atlas Capture

VideoAction Recognition

As a Data Annotation & Atomic Action Labeling Contributor for Atlas Capture, I labeled atomic and hand-action events in video datasets for AI computer vision. My work included applying segmentation, object interaction annotation, and consistent labeling for task-based movements. I ensured adherence to guidelines to support high-quality motion data annotation for AI projects. • Labeled motion sequences using segmentation and annotation standards • Ensured accurate annotation of hand actions and object interactions • Maintained quality-focused annotation for computer vision • Worked directly with video data to support AI learning
