Alak Das, Dibyendu Ghoshal . Extraction of time invariant lips based on Morphological Operation and Corner Detection Method. International Journal of Computer Applications. 48, 21 ( June 2012), 7-11. DOI=10.5120/7478-0518
The study presents a robust yet simple technique for the extraction of lips from human face. Harris corner detection is applied on a morphologically pre-processed human face and the location and dimension of the lips along the horizontal and vertical directions are obtained. The lip dimension thus found is compared with a predetermined dimension of the same obtained through 'data cursor' operator prevailing in Matlab toolbox. The dimension obtained from the present technique is accepted only when they fall within a certain meaningful latter. The proposed technique is found to yield 88% of average correct rate of lip extraction from human faces of ORL Face Dataset.
