Motion recognition

---

• Motion recognition is an important topic in CV
  • HCI, video indexing, video surveillance, entertainment
• Real time reconstruction rates needed for several applications
• Development of a novel technique for fast recognition of human motion
  • Capturing in 3D the motion of a perfomer
  • Representation of the motion as a line in the space of motion parameters
  • Recognition of the motion in the motion parameters space by means of a reduced PCA representation of the movements

• Each motion is divided into set of sequences (group of n consecutive poses)
• Sequences are representative of the type of motion performed
• Extracted sequences are compared with preclassified sequences (used to create PCA representation) for classification
