Image Annotation

ImageBounding Box
I performed high accuracy image annotation using bounding boxes to label and localize objects in large datasets. Drew tight, precise 2d rectangular boxes around target objects like vehicles, pedestrians, products or everyday items while strictly following project guidelines and ontology. I ensured consistent labeling, identified edge cases, and maintained quality standards for computer vision and object detection model training. I also worked on high volume batches with strong attention to detail and fast turnaround.
