  • METHOD OF RECOGNIZING ACTIVITY ON BASIS OF SEMI-MARKOV CONDITIONAL RANDOM FIELD MODEL
    Publication number: 20110077919
    Abstract: A method of recognizing an activity on the basis of a semi-Markov conditional random field (CRF) model is provided. The method includes segmenting an input signal measured by an accelerometer to output frame sequences, extracting training feature vectors from the frame sequences, building a codebook containing kernel vectors from the training feature vectors; quantizing vector sequences into discrete symbol sequences, using linear chain semi-Markov CRF model to compute the likelihood of a label given its corresponding symbol sequence.
