An Image Transform Approach for HMM based Automatic Lipreading

  title={An Image Transform Approach for HMM based Automatic Lipreading},
  author={Gerasimos Potamianos and Hans Peter Graf and Eric Cosatto},
This paper concentrates on the visual front end for hidden Markov model based automatic lipreading. Two approaches for extracting features relevant to lipreading, given image sequences of the speaker's mouth region, are considered: A lip contour based feature approach, which rst obtains estimates of the speaker's lip contours and subsequently extracts features from them, and an image transform based approach, which obtains a compressed representation of the image pixel values that contain the… CONTINUE READING
