“…For future work, most authors emphasize the need for improved feature selection strategies to guarantee the inclusion of significant features, while keeping the number of classification inputs as low as possible, thus reducing processing time [9,15,17,18,29,37,39,41,53,63,65]. To improve classification metrics, IR data could be complemented with information collected from other imaging modalities and/or biological tests [9,26,33,64,70]. The availability of a larger data sample is also mentioned by several studies across the different pathologies, in order to perform more complete testing and ease the implementation of such methodologies in daily practices [9,16,25,26,31,44,46,[52][53][54]58,60,63,65,67].…”
