A TEXT INPUT SYSTEM DEVELOPED USING LIP IMAGE

Abstract

In this thesis, a text input system for the serious disabled by using lips image recognition is presented. This system can be divided into four stages –starting from Acquiring image through CCD , Face Tracking , Lips Image Range Allocation and Extraction , Lips Image Processing and Recognition and Morse code Text input system. We have adopted the technique of image processing to recognize the status of mouth-opened or mouth-closed depending the relative distance between the upper lip and the lower lip. The mouth status opened or closed is then used for signaling the morse code symbols dot and dash. The morse code is decoded to get the alphabet as output. I hope the system can help the serious disabled to communicate with normal people more easily. The image processing techniques are used for face detection in the image then from detected face the lips are extracted. The extracted lips are then used to know the status of mouth opened or closed.
