The thresholds work as for the other filters: after calculating the combing value, if this one is under &lt;tt&gt;thY1&lt;/tt&gt;, the pixel is set to 0, over &lt;tt&gt;thY2&lt;/tt&gt;, it is set to 255, and in between, it is set to the combing value divided by 256. <br /> <br /> The combing value is (upper_pixel - pixel)*(lower_pixel - pixel). Thus, it is not normalized to the range 0..255, because if it was done, value would be close to 1 or 2, no more. That means you can use threshold higher than 255, even if they should not be useful. <br /> <br /> Defaults are &lt;tt&gt;thY1&lt;/tt&gt; = 10 and &lt;tt&gt;thY2&lt;/tt&gt; = 10 (thus making a binary mask). <br /> ----<br /> Back to [[MaskTools]].</div>
