Claim 8:
9. A system comprising:
a first device configured for acquiring a first image and a second image; and
a second device comprising a non-transitory memory for storing an application, the application configured for:
comparing the first image and the second image using a scaled Peak Signal-to-Noise Ratio (sPSNR) to generate an image quality assessment value;
comparing the image quality assessment value with a threshold, wherein the sPSNR is utilized for computer vision for machine learning, wherein the sPSNR is based on the equation:, sPSNR
   =
   
    10
    ⁢
    
     log
     (
     
      
       
        c
        0
       
       ⁢
       
        MAX
        4
       
      
      
       1
       +
       MSE
      
     
     )
    
   
  
  ,
 

 wherein c0 is a scale factor, MAX is a maximum possible pixel value, and MSE is a mean squared error;
comparing luminance, contrast and one or more structures in the first image and the second image to generate a structural similarity index; and
combining the sPSNR and the structural similarity index to determine whether the first image and the second image match.
