SynPASS: Synthetic Panoramic Semantic Segmentation Benchmark

Official Dataset Repository for the SynPASS benchmark (Trans4PASS / Trans4PASS+).

Dataset Description

The SynPASS dataset contains 9,080 panoramic images (1024x2048) across 22 semantic categories. The dataset covers diverse scenarios:

  • Weather: Cloudy, Foggy, Rainy, Sunny
  • Lighting: Day-time, Night-time

Statistics

Condition Cloudy Foggy Rainy Sunny Total
Split (train/val/test) 1420/420/430 1420/430/420 1420/430/420 1440/410/420 5700/1690/1690
Split (day/night) 1980/290 1710/560 2040/230 1970/300 7700/1380
Total Frames 2270 2270 2270 2270 9080

Quick Start & Download

Using the Hugging Face CLI:

# Download dataset archive
hf download InSAI-Lab/SynPASS SynPASS.tar.gz --type dataset --local-dir ./datasets

# Extract archive
cd ./datasets
tar -zxvf SynPASS.tar.gz

Using Python (huggingface_hub):

from huggingface_hub import hf_hub_download

dataset_path = hf_hub_download(
    repo_id="InSAI-Lab/SynPASS",
    repo_type="dataset",
    filename="SynPASS.tar.gz",
    local_dir="./datasets"
)
