# SCaN-TIR: Stereo Clean-and-Noisy Paired Thermal Infrared Dataset

[**TIDY: Thermal Infrared Image Denoising via Wavelet Domain Entropy and Directional Stripe Index**](https://huggingface.co/papers/2606.19813)

[Code](https://github.com/williamrheeth/TIDY) | [Dataset](https://huggingface.co/datasets/williamrhee/SCaN-TIR) | [Video](https://youtu.be/PxcEG1ayDKE)

SCaN-TIR is a real clean–noisy paired thermal infrared dataset for supervised TIR image denoising. It contains over 32.5K hardware-synchronized and geometrically aligned image pairs captured with two adjacent FLIR A65 thermal cameras, where one camera stream was intentionally degraded by disabling non-uniformity correction (NUC). The dataset includes both indoor and outdoor sequences at 640×512 resolution, providing real sensor noise rather than synthetic noise approximations.

## Highlights

* First real stereo clean–noisy paired and aligned TIR dataset
* Over 32.5K synchronized thermal image pairs
* Captured using two adjacent FLIR A65 infrared cameras
* One stream collected with NUC disabled to obtain real noisy thermal images
* Geometrically aligned through stereo rectification using calibrated extrinsics
* Includes both indoor and outdoor sequences
* Provides both Fieldscale-mapped 8-bit images and original 14-bit images
* Designed for supervised real-noise TIR denoising and downstream robotics perception

## Usage

You can download the dataset using the Hugging Face CLI:

```bash
pip install -U "huggingface_hub[cli]"

huggingface-cli download williamrhee/SCaN-TIR \
    --repo-type dataset \
    --local-dir SCaN-TIR
```

## Dataset Structure

The dataset is organized into scene folders containing synchronized clean and noisy thermal infrared images.
