บทคัดย่อ

In this study, the authors address the challenge of removing wrinkled transparent films to reveal obscured information for industrial recognition systems. They introduce an end-to-end framework that utilizes polarization information to decouple specular highlights and other degradations from the film. By creating a practical dataset and conducting extensive experiments, they demonstrate superior performance in image reconstruction and downstream tasks like QR code reading and text OCR.
