Abstract:
A method of living body detection performed with a terminal device includes the following operations. A first image for a target object is obtained via a camera at a first focal length, and a second image for the target object is obtained via the camera at a second focal length. A difference image of the first image and the second image is determined. Whether the target object is a living body is determined according to the difference image.

Claim (Index 5):
The method of  claim 4 , wherein the determining whether the target object is the living body according to the one or more features comprises:\n acquiring a positive sample set and a negative sample set, wherein the positive sample set comprises a plurality of difference images for a plurality of living bodies and the negative sample set comprises a plurality of difference images for a plurality of non-living bodies; extracting a plurality of features from the positive sample set and a plurality of features from the negative sample set; obtaining a first classifier according to the plurality of features extracted from the positive sample set and a second classifier according to the plurality of features extracted from the negative sample set; and determining whether the target object is the living body according to the one or more features, the first classifier, and the second classifier.
