title: [A gait analysis system based on digital video and digital image processing].
abstract: OBJECTIVE
  To provide a gait analysis system.
  
  
  METHODS
  The system is composed of general video devices and personal computer hardware. The techniques of digital video and digital image processing such as template matching, sub-pixel and motion estimate etc were employed to identify and trace the markers.
  
  
  RESULTS
  A gait result of a cerebral palsy object, which consists of bar-figure, data, and video was provided.
  
  
  CONCLUSIONS
  The gait analysis system based on digital video and digital image processing is easy to use, and can provide visual result, which is easy to understand.
