Image Deraining via Self-supervised Reinforcement Learning

Understand

The quality of images captured outdoors is often affected by the weather.

• One factor that interferes with sight is rain, which can obstruct the view of observers and computer vision applications that rely on those images.
• The work aims to recover rain images by removing rain streaks via Self-supervised Reinforcement Learning (RL) for image deraining (SRL-Derain).
• We locate rain streak pixels from the input rain image via dictionary learning and use pixel-wise RL agents to take multiple inpainting actions to remove rain progressively.
