About this Gig

High-performing segmentation models depend on pixel-accurate masks. If you need clean ground truthbeyond boxesmanual mask annotation is the difference between good enough and production-level results.

I provide manual image segmentation (polygon/mask labeling) for semantic or instance segmentation. I focus on boundary accuracy, consistent mask definitions, and careful handling of challenging regions (fine edges, overlaps, motion blur, low contrast).

What you get:

Accurate segmentation masks (polygons / pixel-level)
Semantic or instance labeling (depending on your task)
Clear rules for boundaries, holes, overlaps, and occlusions
Export in formats such as COCO (segmentation), PNG masks, JSON, or your required structure

Send me a message with example images, classes, and the expected output format, and Ill match the annotation style to your project.
