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.
