APPARATUS AND METHOD OF INPUTTING A TEXT USING LIP READING IN A MOBILE PHONE

摘要

PURPOSE: An apparatus for inputting a text using a lip reading method in a mobile phone and a method thereof are provided to input a character by recognizing the motion of a user's mouth. CONSTITUTION: A face location tracking unit(210) detects the motion of a user in a photographing device. A lip motion feature detecting unit(220) extracts a specific vector about an area including the lip shape from the face image by the face location tracking unit. A lip motion extracting unit(230) extracts a feature vector by the movement of the lip among the extracted vectors. A lip motion decoding unit(260) changes the feature vector from the lips motion extracting unit into a corresponding character.
