    <description descriptionType="Abstract">&lt;p&gt;A&amp;nbsp;simple computer vision&amp;nbsp;dataset for shadow detection and texture analysis, specifically created to help test shadow detection algorithms (and texture segmentation algorithms)&amp;nbsp;for mobile robots - that is, shadow detection with an&amp;nbsp;&lt;em&gt;active (moving)&amp;nbsp;camera&lt;/em&gt;.&lt;/p&gt;

&lt;p&gt;The dataset is focused around texture analysis, so each image sequence contains shadows moving in front of a number of various textured surfaces. The dataset contains four main subfolders: &amp;quot;active&amp;quot;, &amp;quot;artificial&amp;quot;, &amp;quot;kondo&amp;quot;, and&amp;nbsp;&amp;quot;static&amp;quot;. The &amp;quot;static&amp;quot; folder contains ground-truthed image sequences of textured surfaces with shadows moving over them,&amp;nbsp;and the &amp;quot;active&amp;quot; folder contains ground-truthed image sequences of a camera travelling over&amp;nbsp;textured surfaces. The &amp;quot;artificial&amp;quot; folder contains a computer-generated 3D scene with computer-generated ground truth, but note that texture is absent from all images within. Finally, the &amp;quot;kondo&amp;quot; folder contains a series of extremely challenging images captured from a webcam mounted to a Kondo bipedal robot. This final dataset is challenging because it contains a high level of noise, flicker and interference from electrical lighting, and the&amp;nbsp;poor&amp;nbsp;lighting conditions make for complex shadows with large penumbrae.&lt;/p&gt;</description>
