Claim 4:
5. The method of claim 1, wherein the third model configured for object detection comprises:
detecting objects in the image;
generating, for each object, an object label and a location;
obtaining, for each object, a relative area measurement as in the following equation, Relative
   ⁢
      
   
    Area
    object
   
  
  =
  
   
    Area

    of
    ⁢
       
    object
   
   
    Area
    ⁢
       
    of
    ⁢
       
    image
   
  
 

where Area of object is a number of pixels represented by each object, and Area of image is a number of pixels of the image the object is detected in; and
determining the third model similarity measure as in the following equation, Third

where A and B are lists of object labels with respective relative area values in the at least one query image and each candidate image of the subset of the first ranked candidate images, respectively, ∩(A, B) is an object label intersection list between A and B, ∩(A, B) comprising common object labels between A and B, ∪(A, B) is an object label union list between A and B, ∪(A, B) comprising unique object labels in A and B, Rargument is the relative area values of one of object labels in the object label intersection list or the object label union list, wherein argument is a criterion of a minimum (min), a maximum (max), and an average (ave) relative area value of the one of object labels.
