Hi All,<div><br></div><div>I am registering with 2 images of the head with BSpline Transformation and Mattes MI.</div><div><br></div><div>I use the mask to exclude the background so the samples for MI are taken only from the head, but the BSpline grid is defined on all image.</div>
<div>The registered image is not correctly deformed. In particular it appears <span class="Apple-style-span" style="font-family: Arial, Helvetica, sans-serif; font-size: 12px; color: rgb(17, 17, 17); ">flattened on the top of the image.</span></div>
<div><span class="Apple-style-span" style="font-family: Arial, Helvetica, sans-serif; font-size: 12px; color: rgb(17, 17, 17); "><span class="Apple-style-span" style="color: rgb(0, 0, 0); font-family: arial; font-size: small; ">I have played with the parameters of optimizer but i have the same result.</span></span></div>
<div><font class="Apple-style-span" face="arial, Helvetica, sans-serif">When I register without the mask the registered image is good.</font></div><div><font class="Apple-style-span" face="arial, Helvetica, sans-serif">Where is the error?</font></div>
<div><font class="Apple-style-span" face="arial, Helvetica, sans-serif">any idea?</font></div><div><font class="Apple-style-span" face="arial, Helvetica, sans-serif"><br></font></div><div><font class="Apple-style-span" face="arial, Helvetica, sans-serif">Thank you for any suggestion.</font></div>
