This paper presents a video tracking system for tracking players in indoor sports using two high quality digital cameras. The tracking algorithm is based on template matching technique taking into consideration closed world assumptions. The output of the system can be visualized interactively for convenient analysis of player movements. The implementation has been efficiently done as a software...

This paper presents visually enhanced sports entertainment applications: AR Baseball Presentation System and Interactive AR Bowling System. We utilize vision-based augmented reality for getting immersive feeling. First application is an observation system of a virtual baseball game on the tabletop. 3D virtual players are playing a game on a real baseball field model, so that users can observe t...

In team sports, players move in complex but surprisingly predictable ways. With state-of-the-art computer vision and machine learning methods, it is now possible to collect sufficiently large player tracking datasets and learn patterns of how players actually move. In this talk, I will describe how this knowledge has been used at Disney Research to generate new analytics and sports broadcasting...

In the field of computer vision, the motion analysis techniques are increasingly robust and beginning to have an impact beyond laboratories. Computers are able nowadays to perform image processing in real time. Indeed, they could be used to build non-intrusive systems for gesture analysis. In particular, gesture and motion analysis is in strong demand in the athletics field. This is especially ...

F physicians, particularly those who work in emergency rooms or act as physicians for sports teams, are often confronted with concussion. Although concussion can result from a variety of everyday activities, this article will focus on sports-related concussion. When the injury happens, physicians must consider whether a player can resume play. If a player cannot resume play immediately, the iss...

The development of computer vision system for tracking players in indoor team games is presented. Several image processing and tracking methods are described, along with camera calibration and lens distortion correction. The output of the system consists of spatiotemporal trajectories of the players, which can be further processed and analyzed by sport experts. In some critical situations the a...

Research of visual perceptual learning has illuminated the flexibility of processing in the visual system and provides insights into therapeutic approaches to remediating some components of low vision. A key observation from research of perceptual learning is that effects of training are often highly specific to the attributes of the trained stimuli. This observation has been a blessing to basi...

INTRODUCTION Visual skills are one of the main pillars of intangible faculties of athletes that can influence their performance. Great number of vision tests used to assess the visual skills and it will be irrational to perform all vision tests for every sport. OBJECTIVES The purpose of this protocol article is to present a relatively comprehensive battery of tests and assessments on static a...

A child suffering from traumatic cataract and corneal astigmatism of 2.14 D had a phacoemulsification operation and implantation of a ReSTOR Toric intraocular lens (IOL) to correct the astigmatism. The primary outcome measurements were the uncorrected distance visual acuity (UDVA), uncorrected near vision at 40 cm, intraocular pressure, spherical equivalent refraction, residual astigmatism, cor...
