Abstract: A method for generating a human face video, an apparatus for generating a human face video, includes: obtaining a mouth-shape multimedia resource and a reference human face image of a target object; obtaining a reference style vector of the target object; for each resource frame in the mouth-shape multimedia resource, obtaining a mouth-shape driving feature by performing a feature extraction process on the resource frame; generating a stylistic human face image corresponding to the resource frame according to the mouth-shape driving feature, the reference human face image, and the reference style vector; and determining a stylistic human face video of the target object.

Abstract: A method for training a model includes: obtaining a scene image, second actual characters in the scene image and a second construct image; obtaining first features and first recognition characters of characters obtained by performing character recognition on the scene image using the model to be trained; obtaining second features of characters obtained by performing character recognition on the second construct image using the training auxiliary model; and obtaining a character recognition model by adjusting model parameters of the model to be trained based on the first recognition characters, the second actual characters, the first features and the second features.
