Abstract: A facial recognition method and device, and relate to the field of computer vision in artificial intelligence (AI). The method includes: obtaining a first face image and a second face image; determining whether a modality of the first face image is the same as a modality of the second face image; if the modality of the first face image is different from the modality of the second face image, separately mapping the first face image and the second face image to a cross-modal space to obtain a first sparse facial feature of the first face image in the cross-modal space and a second sparse facial feature of the second face image in the cross-modal space; and performing facial recognition on the first face image based on the first sparse facial feature and the second sparse facial feature.
