Claim 7:
8. The electronic device according to claim 7, wherein the computer program is executed by the processor to implement:
based on the cosine distance matrix, calculating the difficulty vector corresponding to the multiple identification objects according to the following conditional formula:, C
       i
      
      =
      
       
        max
        
         n
         ≠
         i
        
       
       D
       ⁢
       
        (
        
         i
         ,
         n
        
        )
       
      
     
     ;
     and
    
   
  
  
   
    
     C
     =
     
      {
      
       
        C

        C
        N
       
      
      }
     
    
   
  
 

wherein, “i” indicates that a row number in the cosine distance matrix D is an i-th row, “n” indicates that a column number in the cosine distance matrix D is an n-th row or an n-th column; “C” represents the difficulty vector corresponding to the multiple identification objects; C_i represents a difficulty of distinguishing the identification objects, N represents the number of identification objects.
