    <subfield code="a">&lt;p&gt;This dataset contains scanning electron microscopy (SEM) images of steel alloys, including paired secondary electron (SE2) and in-lens (InLens) channels, with corresponding binary segmentation labels. The data supports full reproduction of results presented in the referenced manuscript.&lt;/p&gt;

&lt;p&gt;&amp;nbsp;&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Dataset Description&lt;/strong&gt;&lt;/p&gt;

&lt;ul&gt;
	&lt;li&gt;&lt;strong&gt;Content:&lt;/strong&gt;&amp;nbsp;13 pairs of SEM images of two reactor pressure vessel (RPV) steels:

	&lt;ul&gt;
		&lt;li&gt;&lt;em&gt;JFL&lt;/em&gt;: IAEA reference RPV base metal steel&lt;/li&gt;
		&lt;li&gt;&lt;em&gt;ANP-10&lt;/em&gt;: Western type RPV steel&lt;/li&gt;
	&lt;/ul&gt;
	&lt;/li&gt;
	&lt;li&gt;&lt;strong&gt;Acquisition:&lt;/strong&gt;
	&lt;ul&gt;
		&lt;li&gt;&lt;em&gt;JFL&lt;/em&gt;: Zeiss NVision 40 microscope&lt;/li&gt;
		&lt;li&gt;&lt;em&gt;ANP-10&lt;/em&gt;: Zeiss Ultra 55 microscope&lt;/li&gt;
		&lt;li&gt;Both SE and InLens detectors used simultaneously.&lt;/li&gt;
	&lt;/ul&gt;
	&lt;/li&gt;
	&lt;li&gt;&lt;strong&gt;Resolution:&lt;/strong&gt;&amp;nbsp;2048 &amp;times; 1404 pixels per image
	&lt;ul&gt;
		&lt;li&gt;2048 px width corresponds to 14.3 &amp;micro;m (JFL) or 11.5 &amp;micro;m (ANP-10).&lt;/li&gt;
	&lt;/ul&gt;
	&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;Using the dataset to reproduce the results of the manuscript&lt;/p&gt;

&lt;p&gt;Download the zip file into the&amp;nbsp;&lt;code&gt;data/&lt;/code&gt; subdirectory of the code repository and extract the archive:&lt;/p&gt;

&lt;pre&gt;&lt;code class="language-bash"&gt;cd data/
unzip data.zip&lt;/code&gt;&lt;/pre&gt;

&lt;p&gt;&lt;strong&gt;Dataset Structure&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;These directories contain the relevant data for the manuscript:&lt;/p&gt;

&lt;p&gt;&lt;code&gt;cloud/&lt;/code&gt;&lt;br&gt;
&lt;code&gt;├-─ preprocessed/&lt;/code&gt;&lt;br&gt;

&lt;code&gt;├── tb_logs/&lt;/code&gt;&lt;br&gt;
&lt;code&gt;│ &amp;nbsp; ├── unet_model/&lt;/code&gt;&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Preprocessed&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;pre-processed whole images and corresponding labels&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Processed Tiles&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;tiled images and labels&lt;/p&gt;
