# Segments.ai
|
||
|
||
## 매 한 줄
|
||
> **"매 computer vision 매 labeling platform — 2D/3D segmentation, point cloud, AI-assisted"**. 매 production tool for multi-modal CV datasets — 매 SAM 2 integration, lidar cuboid, semantic/instance/panoptic segmentation. 매 alternative: Roboflow, Scale AI, Labelbox, CVAT.
|
||
|
||
## 매 핵심
|
||
|
||
### 매 Modalities
|
||
- **2D**: Bounding box, polygon, semantic, instance, panoptic, keypoint.
|
||
- **3D point cloud**: 매 cuboid, segmentation (autonomous driving).
|
||
- **Multi-sensor**: 매 synced lidar + camera (매 AV use case).
|
||
- **Image sequence / video**: 매 tracking 가 supported.
|
||
|
||
### 매 AI-assisted
|
||
- 매 SAM 2 integration: 매 click → instance mask.
|
||
- 매 model-in-the-loop: 매 your trained model 매 pre-label → human correct.
|
||
- 매 active learning: 매 uncertain samples 매 priority queue.
|
||
|
||
### 매 Dataset export
|
||
- COCO, YOLO, Pascal VOC, Cityscapes formats.
|
||
- HuggingFace `datasets` integration.
|
||
- 매 versioning: 매 release immutable snapshots.
|
||
|
||
### 매 응용
|
||
1. Autonomous driving lidar+camera labeling.
|
||
2. Medical imaging segmentation.
|
||
3. Robotics grasp annotation.
|
||
4. Pre-training dataset curation (매 SAM bootstrap).
|
||
|
||
## 💻 패턴
|
||
|
||
### Upload dataset
|
||
```python
|
||
from segments import SegmentsClient
|
||
|
||
client = SegmentsClient(api_key="YOUR_KEY")
|
||
dataset = client.add_dataset(
|
||
name="my-org/road-scenes",
|
||
task_type="segmentation-bitmap",
|
||
description="Highway driving scenes",
|
||
)
|
||
for img_path in image_paths:
|
||
asset = client.upload_asset(open(img_path, "rb"), filename=img_path.name)
|
||
client.add_sample(
|
||
dataset_identifier="my-org/road-scenes",
|
||
name=img_path.name,
|
||
attributes={"image": {"url": asset.url}},
|
||
)
|
||
```
|
||
|
||
### Pre-label with SAM 2
|
||
```python
|
||
from segments.utils import bitmap2file
|
||
import numpy as np
|
||
from sam2.build_sam import build_sam2
|
||
from sam2.sam2_image_predictor import SAM2ImagePredictor
|
||
|
||
sam = build_sam2("configs/sam2.1_hiera_l.yaml", "sam2_hiera_large.pt")
|
||
predictor = SAM2ImagePredictor(sam)
|
||
|
||
predictor.set_image(image)
|
||
masks, _, _ = predictor.predict(point_coords=[[x, y]], point_labels=[1])
|
||
mask = masks[0].astype(np.uint8)
|
||
|
||
bitmap_file = bitmap2file(mask, is_segmentation_bitmap=True)
|
||
asset = client.upload_asset(bitmap_file, filename="mask.png")
|
||
client.add_label(
|
||
sample_uuid=sample.uuid,
|
||
labelset="ground-truth",
|
||
attributes={"format_version": "0.1", "annotations": [...], "segmentation_bitmap": {"url": asset.url}},
|
||
)
|
||
```
|
||
|
||
### Active learning loop
|
||
```python
|
||
def active_learning_round(model, unlabeled_samples, k=100):
|
||
scores = []
|
||
for s in unlabeled_samples:
|
||
img = load_image(s.attributes["image"]["url"])
|
||
logits = model.predict(img)
|
||
entropy = -(logits.softmax(-1) * logits.log_softmax(-1)).sum()
|
||
scores.append((s, entropy.item()))
|
||
top = sorted(scores, key=lambda x: -x[1])[:k]
|
||
for s, _ in top:
|
||
client.update_sample(s.uuid, priority=10) # 매 high priority
|
||
```
|
||
|
||
### Export to HuggingFace
|
||
```python
|
||
from segments.huggingface import release2dataset
|
||
|
||
release = client.add_release("my-org/road-scenes", name="v1.0")
|
||
hf_dataset = release2dataset(release)
|
||
hf_dataset.push_to_hub("my-username/road-scenes-v1")
|
||
```
|
||
|
||
### 3D point cloud cuboid
|
||
```python
|
||
client.add_sample(
|
||
dataset_identifier="my-org/lidar",
|
||
name="frame_001",
|
||
attributes={
|
||
"pcd": {"url": "s3://.../frame_001.pcd", "type": "pcd"},
|
||
"ego_pose": {"position": {"x": 0, "y": 0, "z": 0}, "heading": {...}},
|
||
"default_z": -1.5,
|
||
},
|
||
)
|
||
```
|
||
|
||
### Webhook-driven CI
|
||
```python
|
||
# Flask endpoint receiving Segments.ai webhook
|
||
@app.post("/segments-webhook")
|
||
def on_label_finalized(req):
|
||
event = req.json
|
||
if event["action"] == "labelset.released":
|
||
trigger_training_pipeline(release_uuid=event["release"]["uuid"])
|
||
return {"ok": True}
|
||
```
|
||
|
||
## 매 결정 기준
|
||
| 상황 | Approach |
|
||
|---|---|
|
||
| Multi-modal AV (lidar+cam) | 매 Segments.ai 또는 Scale AI |
|
||
| 2D bbox only | 매 Roboflow (cheaper) |
|
||
| Self-host required | 매 CVAT |
|
||
| Enterprise ops | 매 Labelbox |
|
||
| Quick prototype | 매 Roboflow / LabelStudio |
|
||
|
||
**기본값**: 매 lidar+camera 면 Segments.ai, 매 2D-only 면 Roboflow.
|
||

## 🤖 LLM 활용
|
||
**언제**: 매 production CV labeling pipeline, 매 multi-modal sensor fusion dataset.
|
||
**언제 X**: 매 LLM text labeling (Argilla 사용), 매 small one-off (LabelStudio OSS).
|
||
|
||
## ❌ 안티패턴
|
||
- **No version control**: 매 release snapshot 무시 → 매 reproducibility 불가.
|
||
- **Manual-only labeling**: 매 SAM pre-label 무시 → 10× slower.
|
||
- **Skip QA**: 매 reviewer-disagreement metric 무시 → noisy labels.
|
||
|
||
## 🧪 검증 / 중복
|
||
- Verified (segments.ai docs, Python SDK v1.x).
|
||
- 신뢰도 B+ (commercial product, 매 docs 매 reliable but 매 non-academic).
