<sup>1</sup> "i", "ii", "iii", "iv", and "v" in column "Category in Table 1" correspond to the same category index in Table 1. <sup>2</sup> The "Results" column only provides a statistic summary among the results of related studies. The exact values have no comparability either between each other or with this research. The reason comes from the different research focus, applied data, and experimental environments. The valid quantitative comparisons can be found in Section 3.2.
