I will do bounding box and semantic segmentation annotation
AI Data Annotation Expert, Computer Vision, Image Labeling Specialist
About this Gig
Need precise bounding box or segmentation annotation for your computer vision or machine learning model?
I specialize in high-accuracy, pixel-level and object-level annotation, with 2+ years of experience annotating complex real-world scenes for AI training pipelines, including autonomous vehicle datasets requiring strict accuracy standards.
Annotation types I offer:
Bounding Box Annotation
Semantic & Instance Segmentation
Keypoint Annotation
Pixel-wise Annotation
Lane Annotation (for autonomous driving datasets)
Tools: CVAT, Labelbox
Objects annotated: vehicles, pedestrians, roads, lanes, sidewalks, traffic elements, obstacles, buildings, vegetation
What makes my annotation reliable:
- I follow strict class definitions and edge-case guidelines precisely
- Experienced with QC processes and self-check before delivery
- Comfortable with high annotation density and overlapping objects
- Consistent labeling across large batches

FAQ
What's the difference between semantic and instance segmentation — can you do both?
Semantic segmentation groups all pixels of a class together (e.g., all vehicles = "vehicle"). Instance segmentation separates each individual object. Yes, I can do both — just specify which you need.
Can you follow a specific class taxonomy or label list?
Yes — please share your class list and any edge-case handling rules before ordering so annotations match your exact requirements.
Do you provide annotations in COCO or Pascal VOC format?
Yes, I can export in COCO JSON, Pascal VOC XML, or other common formats — just let me know your preference.
Can you handle overlapping or occluded objects in a scene?
Yes, I have experience annotating dense scenes with overlapping objects and will follow your occlusion-handling guidelines.
Can I see a sample of your annotation work before ordering?
Yes, please check my portfolio samples. I'm also happy to do a small paid test batch first if you'd like to verify quality and fit.
