Image similarity or distortion assessment is fundamental to a broad range of applications throughout the field of image processing and machine vision. Many existing image similarity measures have been proposed to handle specific types of image distortions. Also, there are methods such as the classical structural similarity （SSIM） index that are applicable to a wider range of applications. Most of existing image similarity measures are based on statistical approaches. Image similarity measures th...
