“…Recently, there has been a burst of research on saliency due to its wide application in leading medical disciplines such as neuroscience and cardiology. In fact, when considering medical images like those acquired in magnetic resonance imaging (MRI) or positron emission tomography (PET), the automatic obtention of saliency maps is useful for pathology detection, disease classification [22], location and segmentation of brain strokes, gliomas, myocardium detection for PET images, tumors quantification in FLAIR MRI [23], etc.…”
