摘要： This application discloses a palm image recognition method performed by a computer device. The method includes: performing palm detection on a palm image captured by a camera to generate a palm box for a palm in the palm image (304); determining location information of the palm relative to the camera based on the palm box and the palm image; and displaying a palm identifier corresponding to the palm based on the location information, the palm identifier being used for indicating the palm to move to a preset spatial location corresponding to the camera to obtain an object identifier corresponding to the palm image. A user, based on the palm identifier, moves its palm to the preset spatial location corresponding to the camera to perform palm image recognition.

摘要： A face image quality assessment method includes acquiring a face image, and determining a similarity distribution distance of the face image, the similarity distribution distance including a distribution distance between an intra-person similarity distribution of the face image and an inter-person similarity distribution of the face image. The intra-person similarity distribution indicates a similarity distribution between the face image and a first-type image of a same person as the face image, and the inter-person similarity distribution indicates a similarity distribution between the face image and a second-type image of a different person from the face image. The method further includes determining image quality of the face image based on the similarity distribution distance of the face image.

摘要： The present disclosure discloses a living body identification method, an information generation method, and a terminal, and belongs to the field of biometric feature recognition. The method includes: providing lip language prompt information, the lip language prompt information including at least two target characters, and the at least two target characters being at least one of: characters of a same lip shape, characters of opposite lip shapes, or characters whose lip shape similarity is in a preset range; collecting at least two frame pictures; detecting whether lip changes of a to-be-identified object in the at least two frame pictures meet a preset condition, when the to-be-identified object reads the at least two target characters; and determining that the to-be-identified object is a living body, if the preset condition is met. The present disclosure resolves a problem in the related technology that even if a to-be-identified object performs an operation according to lip language prompt information, a terminal may incorrectly determine that the to-be-identified object is not a living body, and achieves an effect that the terminal can accurately determine whether the to-be-identified object is a living body and improve determining accuracy.
