Lip-reading with discriminative deformable models
Hubert Nowak · International Conference on Computer Vision and Graphics · 2006
The following paper describes a novel lip-reading method developed for the purpose of isolated word recognition. The method is based on a concept of a discriminative deformable model, which represents an image analysis method derived from the deformable grid paradigm. The discriminative deformable model is used to characterize the lip shape at each frame of the video sequence. The information extracted from the consecutive frames is next analyzed using the Hidden Markov Models. The proposed visual speech recognition method is tested using the Polish digits recognition task.
