Scatterplot showing success index versus true accuracy.

<p>X axes show the success index (JC between </p><p></p><p></p><p></p><p><mi>C</mi><mn>2</mn><mo>′</mo></p><p></p><p></p><p></p> and <i>C</i>₂), and y axes show JC between the final generated mask <p></p><p></p><p></p><p><mi>C</mi><mn>2</mn><mo>′</mo></p><p></p><p></p><p></p> and the gold-standard reference label. Left: full range. Right: zoomed on non-outlier data (five outliers are off-scale). Experiments (corresponding to rows in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0129211#pone.0129211.t003" target="_blank">Table 3</a>) are grouped by colour.<p>
