...n [ 1;1], thus the ALFD metric, a A(d i;d j), is also bounded by [ 1;1] since jjˆ(d i;d j)jj 11. Fig.4shows two learned model using our method. One can adopt alternative learning algorithms like SVM [6]. 3.4. Properties In this section, we discuss the properties of ALFD affinity metric a A(d i;d j). Firstly, unlike appearance or spatial metrics, ALFD implicitly exploit the information in all the imag...

...One type of NR IQA resorts to the help of the support vector machine (SVM) [21] to find the underlying relationship of the chosen features and subjective human ratings, e.g., distortion identification-based image verity and integrity evaluation (DIIVINE) [22], blind image integrity notator using DCT statistics (BLIINDS-II) [23], blind/referenceless image spatial quality evaluator (BRISQUE) [24], and no-reference free energy-based robust metric (NFERM) [25]....

...Thus, in order to show the effectiveness of LC-kNN algorithm, we took the kNN as the baseline and made a comparison between kNN, LC-kNN and RC-kNN (random clustering kNN), and several real datasets from UCI [2], medical imaging datasets [6,7], and LIBSVM [3] datasets....
