摘要： A method for setting a lip region of a face included in an image, including setting a first region and a second region in an image including a face, identifying contrast information of the first region, setting a threshold for binarization using the contrast information, and binarizing the second region based on the threshold. A region in which a pixel having an identical binary value continuously distributed within a predetermined number of ranges in the binarized image is set as an eye candidate object. An eye region is then extracted from the eye candidate object based on geometric characteristic of an eye region in an image, and the lip region is set with reference to the extracted eye region based on geometric information of the eye region and the lip region.
