Semantic Segmentation
Every pixel accounted for — no gaps, no overlaps
Semantic segmentation assigns a class to every pixel in the frame. It is the most demanding annotation type and the one that pays back hardest in scene-understanding models — autonomous driving, agriculture, medical imaging and satellite analysis all live on it.

Pixel work is where cheap labelling falls apart
Segmentation is slow, and slow work is where under-trained annotators cut corners: rough boundaries, unlabelled slivers between classes, sky bleeding into buildings.
Our segmentation pod is a specialist team, not general labellers. Boundaries are cut at zoom, and an automated pass flags every unlabelled pixel before delivery.
Send us a sample batchWhat is semantic segmentation?
Semantic segmentation partitions an image into regions where each pixel carries a class label — road, sidewalk, vehicle, vegetation, sky — without distinguishing individual instances.
If you also need each object separated as its own entity, that is panoptic or instance segmentation, which we deliver from the same pipeline.
Where it's used
Built for real production pipelines
Autonomous driving & ADAS
Drivable surface, lane, curb and obstacle classes at full scene coverage.
Satellite & aerial mapping
Land use, water bodies, rooftops and road networks.
Precision agriculture
Crop, soil and weed separation for spray-targeting models.
Retail & warehouse robotics
Floor, shelf, obstacle and free-space segmentation.
Sample work
Raw frame in, training-ready labels out
Real semantic segmentation output from client pilots. Drag the handle on any example to compare the source frame with what we deliver.
BeforeDrivable surface mapping
Every pixel assigned to road, sidewalk, vegetation, building or sky. Curb lines are held to the pixel so lane-keeping models learn a real boundary, not an approximation.
19 classes · 98.8% pixel accuracy · PNG masks
BeforeAgricultural field survey
Aerial imagery segmented into crop, water, bare soil and access tracks so yield models can measure area per class instead of guessing from bounding shapes.
4 classes · 2,400 tiles · GeoTIFF + PNG masks
Samples are representative of delivered work; client-identifying frames are replaced under NDA.
How we work
A spec, a pilot, then volume — in that order
Most labelling projects fail on ambiguity, not effort. We remove the ambiguity first, prove it on a pilot, and only then scale throughput.
Start with a free pilot- 1
Lock the ontology
We turn your class list into an unambiguous written spec with visual examples for every edge case.
- 2
Pilot & calibrate
A small batch is annotated blind by two specialists and compared pixel-for-pixel.
- 3
Production
Daily throughput with per-batch QA reports so you can track quality as it lands.
- 4
Delivery
Masks plus overlay previews so review takes minutes, not hours.
Quality control
- Zero-unlabelled-pixel validation
- Boundary precision review
- Ontology conformance check
- Blind re-annotation on 5% sample
What you receive
- Indexed PNG masks
- COCO panoptic JSON
- Class colour map + ontology doc
- Overlay QA previews
Tools we work in
- CVAT
- Segments.ai
- Label Studio
- Client tooling
This is for you if…
AV and robotics teams needing scene-level understanding
Geospatial analytics companies processing imagery at scale
Research groups with a strict class ontology to honour
Every project runs under NDA with access-controlled workstations. Data is deleted on request after delivery.
Why teams switch
You have three options. Only one of them scales.
Hire in-house
- 6–10 weeks to recruit and train
- Fixed salary cost at variable volume
- QA falls on your ML engineers
Random freelancers
- Every batch looks slightly different
- No written spec, no review pass
- Disappear mid-project
Genius Clipping Path
- Dedicated pod trained on your written spec
- Two-pass QA on every single batch
- Pay per unit — scale up or pause anytime

Before you get in touch
Semantic Segmentation FAQs
Pricing, guidelines, security, rework and export formats — the answers teams usually ask for on the first call.
Why is segmentation priced per image, not per object?+
Because cost tracks scene complexity, not object count. We quote per image after seeing a sample of your real frames.
Can you do panoptic segmentation?+
Yes — semantic classes plus separated instances, delivered as COCO panoptic.
How do you handle ambiguous boundaries like shadows or glass?+
They go into the spec during calibration and get a documented rule, so the whole dataset treats them the same way.
Can we run a free pilot before committing?+
Yes. Send 50–100 representative images and we label them free against your guideline draft, usually within 24 hours, so you can measure quality on your own data before any invoice.
How do you handle our annotation guidelines?+
You can send an existing spec or start from a call. We turn it into a written guideline with edge-case examples, get your sign-off, and every annotator is trained and tested against it.
What happens if labels come back wrong?+
Rework is free. Flag the batch within 7 days of delivery, we correct the affected items and update the guideline so the same error class does not repeat.
How do you keep our data secure?+
NDAs on request, access-controlled workstations, no personal devices or external storage, project-scoped access per annotator, and permanent deletion after delivery when you ask for it.
Which export formats do you deliver?+
COCO JSON, YOLO txt, Pascal VOC XML, KITTI, CSV, or masks as PNG. If you use a custom schema or a platform like Labelbox, CVAT, or V7, we deliver straight into it.
How fast can you scale up?+
A dedicated pod starts at 3 annotators and scales to 100+ within about a week, with a QA lead assigned to your project throughout so quality holds as volume grows.
How does billing work?+
Pay per unit with volume tiers, or a fixed monthly dedicated-pod rate. You get an itemised invoice per batch, no setup fee, and no minimum contract on pay-per-unit work.
