Lip Reading Based on Sampled Active Contour Model
This paper describes a model-based method for detecting lip region from image sequences. Our approach is by Sampled Active Contour Model (S-ACM). The original S-ACM has the problem which can’t expand. To overcome this problem, we propose the elastic S-ACM. Moreover, based on the extracted lip contour, the effective delta radius features are fed to the word HMM. We recorded ten words that uses f...
متن کاملLIP Contour Extraction Using a Deformable Model
The use of visual information from lip movements can improve the accuracy and robustness of a speech recognition system. Accurate extraction of visual features associated with the lips is thus very important. In this paper, we present a deformable model-based technique for lip contour extraction from color lip images. The geometric lip model we proposed is able to fit different lip shapes. Our ...
متن کاملA System for Automatic Lip Reading
In this paper, we present our approach of face and lip detection, lip modeling, and tracking. A new lip model based on Bézier Curves is used to capture the dynamics of the lips efficiently. The model is defined only through few points which are modeled using the Active Shape Model (ASM). Accurate detection of lip details is implemented using multiple independent feature templates. The method de...
متن کاملLip Contour Extraction based on Active Shape Model and Snakes
In this paper, we propose an efficient method for extracting lip contour. Lip shape deformation is modeled by a statistically deformable model based on Active Shape Model(ASM). In the traditional ASM, each landmark point is moved independently to the best matching point with lip profile model, so it deforms the lip shape to implausible one in many cases and may cause many errors for extracting ...
