GestureUtils Utility functions for gesture processing & analysis, including methods for:
  • feature extraction (e.g., samplers and those for calculating bounding boxes and gesture path lengths);
  • geometric transformation (e.g., translation, rotation and scaling);
  • gesture similarity comparison (e.g., calculating Euclidean or Cosine distances between two gestures). 
OrientedBoundingBox An oriented bounding box
