Lip
Shape Analysis |
|
In this research, an
imaging system was built to work with a newly
developed electronic device to help people produce
sounds correctly. The system consists of two
parts, the internal tongue contact pattern data
collection and the external lip shape information
analysis. The lip shape information was collected
by processing images taken from people
articulating different sounds. We developed an
efficient color image segmentation technique to
extract lip contour points and form a closed curve
for shape analysis.
