    <description descriptionType="Abstract">&lt;p&gt;&lt;strong&gt;Electrolyzers-HSI Dataset&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;Description:&lt;/p&gt;

&lt;p&gt;The Electrolyzers-HSI dataset is a multiscene RGB-Hyperspectral benchmark dataset comprising 55 scene of shredded Electrolyzers samples. The RGB images are collected using a Teledyne Dalsa C4020 camera on a conveyor belt, while hyperspectral images (HSI) are acquired with a FENIX spectrometer. The HSI data contains 450 bands in the VNIR and SWIR range [400 - 2500]nm.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Data Format&lt;/strong&gt;&lt;/p&gt;

&lt;ul&gt;
	&lt;li&gt;RGB Images: .jpg files&lt;/li&gt;
	&lt;li&gt;Ground Truth (GT): .png files. They appear black since the values are between 0 and 5. Correct visualization is done via script.&lt;/li&gt;
	&lt;li&gt;HSI Data: Each hyperspectral data cube .img file is accompanied by a .hdr file.&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;&lt;strong&gt;Folder Organization&lt;/strong&gt;&lt;/p&gt;

&lt;ul&gt;
	&lt;li&gt;&lt;strong&gt;Electrolyzers-HSI: &lt;/strong&gt;55 subfolders&amp;nbsp;

	&lt;ul&gt;
		&lt;li&gt;1/
		&lt;ul&gt;
			&lt;li&gt;&amp;rsquo;GT.png&amp;rsquo; file for segmentation ground truth&lt;/li&gt;
			&lt;li&gt;&amp;lsquo;HSI.img&amp;rsquo; and &amp;lsquo;HSI.hdr&amp;rsquo; files for HSI data cube&lt;/li&gt;
			&lt;li&gt;&amp;lsquo;RGB.jpg&amp;rsquo; file for the RGB image&lt;/li&gt;
		&lt;/ul&gt;
		&lt;/li&gt;
		&lt;li&gt;2/
		&lt;ul&gt;
			&lt;li&gt;&amp;rsquo;GT.png&amp;rsquo; file for segmentation ground truth&lt;/li&gt;
			&lt;li&gt;&amp;lsquo;HSI.img&amp;rsquo; and &amp;lsquo;HSI.hdr&amp;rsquo; files for HSI data cube&lt;/li&gt;
			&lt;li&gt;&amp;lsquo;RGB.jpg&amp;rsquo; file for the RGB image&lt;/li&gt;
		&lt;/ul&gt;
		&lt;/li&gt;
		&lt;li&gt;3/4/5/6/ &amp;hellip; :Same structure for all rest of folders&lt;/li&gt;
	&lt;/ul&gt;
	&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;&lt;strong&gt;Data Classes in Masks&lt;/strong&gt;&lt;/p&gt;

&lt;ul&gt;
	&lt;li&gt;Masks contain 0 to 5 segmentation classes:
	&lt;ul&gt;
		&lt;li&gt;0: background&lt;/li&gt;
		&lt;li&gt;1: &amp;ldquo;MESH&amp;rdquo;&lt;/li&gt;
		&lt;li&gt;2: &amp;ldquo;Steel_Cathode&amp;rdquo;&lt;/li&gt;
		&lt;li&gt;3: &amp;quot;Steel_Anode&amp;rdquo;&lt;/li&gt;
		&lt;li&gt;4: &amp;ldquo;HTEL_Anode&amp;rdquo;&lt;/li&gt;
		&lt;li&gt;5: &amp;ldquo;HTEL_Cathode&amp;rdquo;&lt;/li&gt;
	&lt;/ul&gt;
	&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;&lt;strong&gt;Code Repository&lt;/strong&gt;&lt;/p&gt;
