Abstract: The present invention provides a face recognition method and device. The method includes: performing down-sampling of different sizes on an original face image; performing block partition processing on a down-sampled image and the original face image; extracting feature of each image block; performing similarity matching between the extracted feature of each image block and features of image blocks corresponding to a pre-registered face image to obtain a similarity of each image block; and obtaining a face image recognition result according to an obtained similarity between all the image blocks. According to the face recognition method and device, down-sampling of different sizes is performed on an original face image, which increases a capability of face image features to describe the face image; a face image recognition result is obtained according to a similarity between all the obtained image blocks, which increases an accuracy of face image recognition.
