<div>Dear All,<br>I am trying to write a 3D MI rigid <span class="st" id="st" name="st">registration</span> program which using itkPowellOptimizer as optimizer. But the result often trapped in the local maximum point. Can any one tell me how to set parameters of itkPowellOptimizer (like step tolerance, value tolerance, etc.) so that it is better for <span class="st" id="st" name="st">registration</span>? Thanks a lot.<br>
<br>Best regards,<br>Ronald</div></div>
