The key attitude based on statistical feature extraction method motion analysis

The key posture extraction method based on statistical analysis of the characteristics of movement involves moving object detection field. The present invention pyramid LK method is applied to optical flow motion video weightlifting, established four space-time channel descriptors, the characteristics of the statistical analysis applied to weightlifting, and found the most intensity value for each channel and the key points to be extracted gesture They are closely linked. For the coaches want to see the detailed analysis of the key frames and is of great significance for training athletes lifting weights.
