Vector Autoregressive Hierarchical Hidden Markov Models for Extracting Finger Movements Using Multichannel Surface EMG Signals

Figure 4

VARHHMM flowchart. At the hierarchically higher HMM layer, the two algorithms are split before the Bayesian inference layer. While one algorithm for HMM (orange path) is the same as the HMM for segments, the other algorithm is based on hidden semi-Markov model (HSMM) paradigm that incorporates movement duration as a free parameter.
