 +===== Abstract ===== 
 +Motion blur often affects the ball image in photographs and video frames in many sports such as tennis, table tennis, squash and golf. In this work, we operate on a single calibrated image depicting a moving ball over a known background, and show that motion-blurred ball images, usually unwelcome in computer vision, bear more information than a sharp image. We provide techniques for extracting such information ranging from low-level image processing to 3D reconstruction,​ and present a number of experiments and possible applications,​ such as ball localization with speed and direction measurement from a single image, and ball trajectory reconstruction from a single long-exposure photograph.

 This paper presents a novel and user friendly input device for 3D curves. The system is based on a piece of flexible wire and a single off-the-shelf photo camera: the user bends the wire to the desired 3D shape; then, an ad-hoc technique for 3D reconstruction is used to recover its 3D shape (a space curve) from a single image. This paper presents a novel and user friendly input device for 3D curves.
