Babu, Venkatesh R and Anantharaman, B and Ramakrishnan, KR and Srinivasan, SH (2001) Compressed Domain Action Classification Using HMM. In: IEEE Workshop on Content-Based Access of Image and Video Libraries, 2001. (CBAIVL 2001), 14 December, Kauai, Hawaii, pp. 44-49.
This paper proposes three techniques for person independent action classification in compressed MPEG video. The features used are based on motion vectors, obtained by partial decoding of the MPEG video. The features proposed are projected ID, 2D polar and 2D Cartesian. The feature vectors are fed to Hidden Markov Model (HMM) for classification of actions. Totally seven actions were trained with distinct HMM for classification. Recognition results of more than 90% have been achieved. This work is significant in the context of emerging MPEG-7 standard for video indexing and retrieval.
