Runway Object-Oriented Bounding Box (OBB) Mask2Former Dataset v2

Dataset Description

This dataset contains aerial/satellite imagery for runway segmentation using Mask2Former architecture. The dataset supports both semantic and instance segmentation tasks, specifically designed for runway detection and delineation in aerial imagery.

Key Features

—Architecture: Optimized for Mask2Former universal segmentation
—Task Support: Semantic, instance, and panoptic segmentation
—Format: COCO-style annotations + semantic masks
—Domain: Aerial/satellite runway imagery

]

Usage

Loading the Dataset

python

from datasets import load_dataset

dataset = load_dataset("Spatiallysaying/rwy_obb_mask2former-300-65-65")

# Load class mappings
import json
with open('id2label.json', 'r') as f:
    id2label = json.load(f)
with open('label2id.json', 'r') as f:
    label2id = json.load(f)
with open('categories.json', 'r') as f:
    categories = json.load(f)

Using with Mask2Former

python

from transformers import Mask2FormerImageProcessor, Mask2FormerForUniversalSegmentation
import torch
from PIL import Image
import numpy as np

# Load model and processor
processor = Mask2FormerImageProcessor.from_pretrained("facebook/mask2former-swin-large-ade-semantic")
model = Mask2FormerForUniversalSegmentation.from_pretrained("facebook/mask2former-swin-large-ade-semantic")

# Load image and semantic mask
image = Image.open("path/to/image.jpg")
semantic_mask = np.array(Image.open("path/to/semantic_mask.png"))

# Process for training
inputs = processor(images=image, segmentation_maps=semantic_mask, return_tensors="pt")

Data Types

—Images: RGB images in JPEG format
—Semantic Labels: Grayscale segmentation masks in PNG format
—Pixel values correspond to class IDs (0=background, 1=runway)
—Instance Annotations: COCO-format JSON files per image
—Bounding boxes, segmentation polygons, areas, category IDs
—Resolution: Variable (original image dimensions preserved)

Annotation Format (COCO-style)
