Viterbi decoding process: (A) 5 categories to 3 primary states, (B) hidden Markov model matrices—transition matrix showing probabilities between states and emission matrix showing a relationship between true and observed states, and (C) example of the Viterbi decoding process for finding a physical examination within a video. PE: physical examination.
