Claim 19:
20. The computer-readable storage medium according to claim 19, wherein training the second neural network model comprises:
obtaining a face image set comprising a plurality of training face images;
training the second neural network model based on the face image set to obtain a probability of each of the training face images being of each of predefined N-type blur levels, wherein N≥2;
calculating a score of blurriness of a human face in each of the training face images based on the probability of each of the training face images being of each of predefined N-type blur levels; and
in response to a preset loss function converging, stopping the training of the second neural network model, wherein the loss function is configured to indicate a difference between the calculated score of blurriness of a human face in each of the training face images and a pre-flagged score of blurriness of the human face in a corresponding one of the training face images.
