Study on Lipreading Recognition Based on Computer Vision
He Liu · 2010
The method of extracting characteristic parameters of lip according to lip template was presented. A dynamic clustering algorithm to classify the lip-shape based on the criteria of the least square error sum was proposed, and dynamic state sequence that described the lip movement was obtained by the improved ant colony algorithm. The lip-reading dynamic pattern recognition was performed by DTW algorithm. Experiments show the method of lip-reading recognition has satisfactory result in classifying isolated syllables.
