Labeling Experience

Volleyball Bounding Box Annotator | CVAT Practice Project

CVATImageBounding Box

Independently designed and executed a volleyball bounding box annotation project to meet OpenTrain AI requirements. Annotated volleyballs in varied scenarios including indoor, outdoor, aerial, and challenging backdrops with strict adherence to guidelines. Demonstrated proficiency in identifying, labeling, and excluding non-active game balls using RECTANGLE SHAPE tool in CVAT. • Covered five distinct sports annotation scenarios • Accurately labeled motion-blurred and partially obscured volleyballs • Applied project-specific label conventions and tight box placement • Excluded irrelevant or non-active game balls as required.
