1. A processor-implemented liveness detection method, comprising:
detecting a face region in an input image;
measuring characteristic information of the face region, wherein the characteristic information includes a hue value, a gamma value and a brightness value of the face region;
in response to a determination that a feature value of the measured characteristic information includes the hue value, the gamma value, and the brightness value is not included in a predetermined feature value range measured from other images, generating an adjusted face region by adjusting the characteristic information of the face region; and
performing a liveness detection on the adjusted face region.
