Lip Features Automatic Extraction
An algorithm for speaker's lip segmentation and features extraction is presented in this paper. A c olor video s e quence o f s p e aker's face i s a c quired, under natural lighting conditions and without any particular make-up. First, a logarithmic color transform is performed f r om RGB to HI hue, intensity color space. Second, a statistical approach using Markov random eld modeling determin...
متن کاملLip Tracking Towards an Automatic Lip Reading Approach
Current era is to make the interaction between humans and their artificial partners (Computers) and make communication easier and more reliable. One of the actual tasks is the use of vocal interaction. Speech recognition may be improved by visual information of human face. In literature, the lip shape and its movement are referred to as lip reading. Lip reading computing plays a vital role in a...
متن کاملUsing aerial and geometric features in automatic lip-reading
In this paper we present the lip-reading experiments with different sets of the features extracted from the video sequence. In our experiments we use a simple color based filtering techniques to extract the feature vectors from the incoming video signal. Some of those features are directly related to the geometrical properties of the lips (their position and visible thickness). Other features r...
متن کاملAutomatic Lip Contour Tracking and Visual Character Recognition for Computerized Lip Reading
Computerized lip reading has been one of the most actively researched areas of computer vision in recent past because of its crime fighting potential and invariance to acoustic environment. However, several factors like fast speech, bad pronunciation, poor illumination, movement of face, moustaches and beards make lip reading difficult. In present work, we propose a solution for automatic lip c...
متن کاملAutomatic and Accurate Lip Tracking
Lip segmentation is an essential stage in many multimedia systems such as videoconferencing, lip reading, or low bit rate coding communication systems. In this paper, we propose an accurate and robust quasi automatic lip segmentation algorithm. First, the upper mouth boundary and several characteristic points are detected in the fi rst frame by using a new kind of active contour : the “jumping ...
