PolarFree: Polarization-based Reflection-Free Imaging

Dataset Overview

PolarFree is a high-quality dataset designed for polarization-based reflection removal tasks, as introduced in the CVPR 2025 paper "PolarFree: Polarization-based Reflection-Free Imaging". The dataset aims to support tasks such as image reflection removal and image enhancement, particularly suitable for training and evaluating image enhancement models.

Dataset Structure

The dataset is organized as follows:

  • input/scene_id/: Contains multiple input images captured at different polarization angles. Each group of images shares the same prefix number (e.g., 000, 001), indicating they belong to the same set.
  • gt/scene_id/: Contains the corresponding high-quality ground truth images used as references for the input images.
