Labeling Experience

Image & Video Data Annotation and AI Training Support

VideoVideoBounding BoxBounding Box

Worked on both image and video data annotation projects to support computer vision and AI model training. For image data, performed high-accuracy labeling including bounding boxes, segmentation masks, and classification across various datasets such as urban environments, people, vehicles, and general objects. For video data, annotated frame-by-frame objects, performed object tracking, temporal labeling, and activity recognition tasks to support motion-based AI models. Ensured consistency and quality by strictly following annotation guidelines, conducting self-review, and correcting labeling errors before submission. Utilized tools such as Labelbox, CVAT, and YOLO annotation formats. Collaborated with QA workflows to maintain dataset accuracy, reduce noise, and improve model performance.
