Optical blur is an inherent property of any lens system and is challenging to model in modern cameras because of their complex optical elements.

Learned Dual-View Reflection Removal

Traditional reflection removal algorithms either use a single image as input, which suffers from intrinsic ambiguities, or use multiple images from a moving camera, which is inconvenient for users.

We propose a way to explicitly encode facial symmetry and show that our dataset and training procedure enable the model to generalize to images taken in the wild.

Zoom To Learn, Learn To Zoom

We show how to obtain the ground-truth data with optically zoomed images and contribute a dataset, SR-RAW, for real-world computational zoom.
