<div dir="ltr"><div>Hi,</div><div>The FDK filter is a composite filter. The ramp filter, which does the truncation correction, is one of the filters. You can simply do feldkampCUDA->GetRampFilter()->GetOutput() to get this intermdiate result.</div><div>Simon<br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, Apr 9, 2024 at 8:46 AM 948206097 <<a href="mailto:948206097@qq.com">948206097@qq.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div><br></div><div><div><br></div><div><img src="cid:ii_18ec19d7694793471ca1" id="m_-4077728740999663116img_insert_1712643099734027172790173502004"><br><img src="cid:ii_18ec19d7694e0a083312" id="m_-4077728740999663116img_insert_171264310477204969479321374368"><br><br></div><div style="font-size:12px;font-family:Arial Narrow;padding:2px 0px">------------------ 原始邮件 ------------------</div><div style="font-size:12px;background:rgb(239,239,239);padding:8px"><div><b>发件人:</b> "948206097" <<a href="mailto:948206097@qq.com" target="_blank">948206097@qq.com</a>>;</div><div><b>发送时间:</b> 2024年4月9日(星期二) 中午1:51</div><div><b>收件人:</b> "rtk-users"<<a href="mailto:rtk-users@openrtk.org" target="_blank">rtk-users@openrtk.org</a>>;</div><div></div><div><b>主题:</b> How to output the image after truncation correction and ramp filtering?</div></div><div><br></div><p class="MsoNormal"><span lang="EN-US">Dear RTK Team</span><span style="color:rgb(51,51,51);background:white">:</span></p>
