According to the availability of the whole or partial original undistorted image (often called reference image), image quality assessment (IQA) algorithms are typically divided into three categories as follows: 1) full-reference IQA (FR-IQA), 2) reduced-reference IQA (RR-IQA), and 3) no-reference IQA (NR-IQA).
