uois-toolkit 0.1.3

A toolkit for loading Unseen Object Instance Segmentation (UOIS) datasets.

One unified interface for 5 UOIS datasets.
Load, augment, train, and evaluate — in 3 lines of code.

---

Why uois_toolkit?

Problem	Solution
Every UOIS dataset ships its own format and loader	Unified API — one interface across all 5 datasets
Evaluation setup eats up research time	Built-in metrics — F1, IoU, Precision, Recall in a single call
Mixing synthetic and real data takes custom wiring	Multi-dataset DataModule with balanced sampling out of the box
Reproducing baselines means writing glue code	Lightning-native — drop into any training loop

---

Quickstart

pip install uois-toolkit

from uois_toolkit import get_datamodule, cfg

dm = get_datamodule("ocid", "/path/to/OCID", batch_size=4, config=cfg)
dm.setup()
batch = next(iter(dm.train_dataloader()))
# batch["image_color"]  → [B, 3, H, W]
# batch["depth"]        → [B, C, H, W]
# batch["annotations"]  → per-image bboxes + RLE masks

Same API for all datasets — just swap the name: "tabletop", "osd", "robot_pushing", "iteach_humanplay".

Usage

Load a single dataset

from uois_toolkit.datasets import OCIDDataset
from uois_toolkit import cfg

dataset = OCIDDataset(image_set="test", data_path="/path/to/OCID", config=cfg)
sample = dataset[0]
# Keys: file_name, image_id, height, width, image_color, depth, raw_depth, annotations

Evaluate predictions

import numpy as np
from uois_toolkit.metrics import compute_metrics

gt_mask = ...   # [H, W] binary
pred_mask = ... # [H, W] binary

results = compute_metrics(gt_mask, pred_mask, ["f1_score", "iou", "precision", "recall"])
# {'f1_score': 0.89, 'iou': 0.80, 'precision': 0.92, 'recall': 0.86}

Train with PyTorch Lightning

from uois_toolkit import get_datamodule, cfg

dm = get_datamodule("tabletop", "/data/tabletop", batch_size=8, config=cfg)
trainer = pl.Trainer(accelerator="auto", max_epochs=10)
trainer.fit(model, datamodule=dm)

Batch format

Key	Shape	Description
image_color	[B, 3, H, W]	RGB image (float)
depth	[B, C, H, W]	Depth map
annotations	List[List[Dict]]	Per-image object annotations

Each annotation: {"bbox": [x1,y1,x2,y2], "segmentation": <RLE>, "category_id": 1}

Installation from source

git clone https://github.com/jishnujayakumar/uois_toolkit.git
cd uois_toolkit
pip install -e .

Note: detectron2 is needed for mask utilities. Install a build that matches your PyTorch + CUDA version.

---

Testing

python -m pytest test/test_datamodule.py -v \
  --dataset_path tabletop=/data/tabletop \
  --dataset_path ocid=/data/OCID \
  --dataset_path osd=/data/OSD

CI runs on every push and PR via GitHub Actions.
