# Systematic Review of Anomaly Detection in Hyperspectral Remote Sensing Applications
## 2 Part A: Bibliometric Analysis
### Authors Analysis  
The 20 most relevant authors, sorted by number of total citations and respective bibliometric statistics, are listed in Table 3. [PERSON] was the most cited author, with 1259 citations from 10 publications. He was followed by [PERSON] with 1044 citations, who was the second most productive author with 12 publications. The most productive author, with 13 publications, was [PERSON]. Scientific production over the time span of the research (Table 1) for the top 10 authors by number of articles and total number of citations per year is presented in Figure 3. The most cited author has also been the most persistent author in the field, with his first publication originating back in 2001 and the last published in 2019. It is interesting to see that the second most cited author has also been the second most persistent, publishing articles from 2007 to 2019. It can be noticed that some authors listed in Figure 3 are not listed in Table 3, and the reason is that sorting in Figure 3 included the normalization of citations per year. Hence, some authors had recently published quality papers with high citation rates, but the total number of citations was still not high enough to earn them a place in Table 3.  
Tables 4 and 5 contain the top documents measured by global and local citations, respectively. Table 4 relates to the publications that were selected within the search strategy, sorted by global citations. Table 5 refers to documents that were highly cited locally but not enclosed by the search strategy results. The work of [PERSON] et al. (2015) received the highest number of global citations and the second-highest number of local citations. In the analyzed document list (Figure 1), the work of [PERSON] and [PERSON] (2018) was appreciated the most, but it also attracted significant attention from the general scientific community, with 470 global citations. The more recent work on collaborative representation for hyperspectral anomaly detection by [PERSON] and [PERSON] (2018) should be underlined, as it received great attention, both globally or locally.
