We propose a method for jointly estimating the 3D motion, 3D shape, and appearance of highly motion-blurred objects from a video. ...
To this end, we model the blurred appearance of a fast moving object in a generative fashion by parametrizing its 3D position, rotation, velocity, acceleration, bounces, shape, and texture over the duration ...

We present an algorithm for analyzing a single calibrated image of a ball and for reconstructing its instantaneous motion (3D velocity and spin) by exploiting motion blur. ...
In a broader scenario, we exploit this specific problem for discussing motivations, advantages and limits of reconstructing motion from motion blur. ...
On the other hand, the problem of estimating the motion of a ball in the 3D space has been extensively treated in video tracking literature (Gopal Pingali and Jean, 2000; J Ren and Xu, 2004; Jonathan ...
