<div><br></div>Hi Felix,<div><br></div><div><br></div><div>1) No, the moments calculators, and therefore the CenteredTransformInitializers does</div><div> not take the masks into account when computing the initialization of the Transform.</div>
<div><br></div><div><br></div><div>2) This could be done by modifying the code of both classes... The changes will</div><div> include to add methods SetFixedSpatialObjectMask() SetMovingSpatialObjectMask(),</div><div>
and inserting if() statements in the main loop that computes the moments.</div><div><br></div><div><br></div><div>When drinking the proper blend of coffee, this could be done in an afternoon,</div><div>and the changes could be submitted to the Insight Journal the following day :-)</div>
<div><br></div><div>Would you like to attempt these modifications ?</div><div><br></div><div>If so, we will be happy to guide you through the process.</div><div><br></div><div><br></div><div> Please let us know,</div>
<div><br></div><div><br></div><div> Thanks</div><div><br></div><div><br></div><div> Luis</div><div><br></div><div><br><br></div><div>---------------------------------------<br><div class="gmail_quote">

<br>What would be the best way to calculate Moments using only the masked regions (in the full images coordinates though)?<br> - at the moment I use the masks themselves for calculating the centers, which is not quite the same.<br>
