Claim 6:
7. The method according to claim 6, wherein the score of blurriness of the human face in each of the training face images is calculated according to a following formula:, E
      ⁡
      
        (
        O
        )
      
    
    =
    
      
        
          ∑
          N
        
        i
      
      ⁢

          o
          i
        
      
    
  
  ,, where E(O) represents the score of blurriness of the human face, yi represents the probability of each of the training face images being of a predefined i-type blur level, and Oi represents a score of the i-type blur level.
