Claim 0:
1. A method programmed in a non-transitory memory of a device, the method comprising:
acquiring a first image and a second image;
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

    .
   
  
 

 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.
