Deblatting (deblurring and matting) of fast moving objects

Restoration of motion-blurred objects. From the given input image containing the blurred object in front of a static background and a separate background image the task is to estimate the shape and restore the sharp appearance of the object as well as its motion blur (trajectory). At its current state the approach is limited to 2D objects and 2D motions, although some preliminary experiments with 3D have been made (see e.g. Rozumnyi CVPR20).
