Labeling Experience

Data Annotator (Freelance/Contract)

ImageBounding Box
I executed image annotation tasks that included object detection and image categorization to enhance computer vision training sets. This required applying bounding boxes to images and categorizing objects to support the development of robust vision models. The work involved careful attention to detail for labeling accuracy. • Object detection using bounding boxes • Image categorization for vision datasets • Quality assurance through detailed review • Support for computer vision model training.
