  "abstract": "<p>Synthetic Datasets for ICSC Flagship 2.6.1. &quot;Fast Extended Computer Vision&quot;&nbsp; paper #1 &quot;Datacube segmentation via Deep Spectral Clustering&quot;</p>\n\n<p>It is a preliminary paper for the ICSC Spoke 2 WP6 flagship 2.6.1 &quot;Fast Extended Computer Vision&quot;.</p>\n\n<p>Code repository at: https://github.com/ICSC-Spoke2-repo/FastExtendedVision-DeepCluster</p>\n\n<p>Abstract:</p>\n\n<blockquote>\n<p>Extended Vision techniques are a ubiquitous in physics. However, the&nbsp; data cubes steaming from such analysis often pose a challenge in their interpretation, due to the intrinsic difficulty in discerning the relevant information from the spectra composing the data cube.<br>\nFurthermore, the huge dimensionality of data cube spectra poses a complex task in its statistical interpretation; nevertheless, this complexity contains a massive amount of statistical information that can be exploited in an unsupervised manner to outiline some essential properties of the case study at hand, e.g.~it is possible to obtain an image segmentation via (deep) clustering of data-cube&#39;s spectra, performed in a suitably defined low-dimensional embedding space.<br>\nTo tackle this topic, we explore the possibility of applying unsupervised clustering methods in encoded space, i.e.~perform deep clustering on the spectral properties of datacube pixels. A statistical dimensional reduction is performed by an ad hoc trained AutoEncoder, in charge of mapping spectra into lower dimensional metric spaces, while the clustering process is performed by an iterative K-Means clustering algorithm.<br>\nWe apply this technique on two different use cases, of different physical origin: a set of MA-XRF data on pictorial artworks, and a synthetic dataset of simualted astrophysical observations.</p>\n</blockquote>",
