Abstract
The present disclosure relates to methods and apparatuses for liveness detection, electronic devices, and computer readable storage media, improving the accuracy of liveness detection. The method includes: carrying out feature extraction on a collected image to obtain image feature information; determining a modality classification result of the image based on the image feature information, the modality classification result indicating that the image corresponds to a target modality in at least one modality; and determining whether a target object in the image is living based on the modality classification result of the image.
