title: Which F1-score is used for the semantic segmentation tasks?
body: <p>I read some papers about state-of-the-art <strong>semantic segmentation</strong> models and in all of them, authors use for comparison F1-score metric, but they did not write whether they use the &quot;micro&quot; or &quot;macro&quot; version of it.</p>
  <p>Does anyone know which F1-score is used to describe the segmentation results and why it is so obvious that authors do not define it in papers?</p>
