+    https://arxiv.org/abs/1706.08500#. The inputs for this metric should be two groups of feature vectors (with format
+    (number images, number of features)) extracted from the a pretrained network.
+
+    Originally, it was proposed to use the activations of the pool_3 layer of an Inception v3 pretrained with Imagenet.
+    However, others networks pretrained on medical datasets can be used as well (for example, RadImageNwt for 2D and
+    MedicalNet for 3D images). If the chosen model output is not a scalar, usually it is used a global spatial
