<div dir="ltr">It's taking me longer than I thought it would to put a main function together, so I thought I would get you some image data to look at. This is a virtual phantom I generated, a white cube on a black background. The second image is the same cube but rotated by 5 degrees in the X direction. The .nfo files contain information about the image size and spacing. Let me know if you find anything out, I'll keep working on getting you a simple main function in case you need it.<div><br></div><div>Thanks again.<div class="gmail_chip gmail_drive_chip" style="width:396px;height:18px;max-height:18px;padding:5px;color:rgb(34,34,34);font-family:arial;font-style:normal;font-weight:bold;font-size:13px;border:1px solid rgb(221,221,221);line-height:1;background-color:rgb(245,245,245)"><a href="https://drive.google.com/file/d/0B_DYTA-i186ZVm1xUndWd0xPeE0/view?usp=drive_web" target="_blank" style="display:inline-block;max-width:366px;overflow:hidden;text-overflow:ellipsis;white-space:nowrap;text-decoration:none;padding:1px 0;border:none"><img style="vertical-align: bottom; border: none;" src="https://ssl.gstatic.com/docs/doclist/images/icon_10_generic_list.png"> <span dir="ltr" style="color:rgb(17,85,204);text-decoration:none;vertical-align:bottom">PhantomBox.nfo</span></a><img src="//ssl.gstatic.com/ui/v1/icons/common/x_8px.png" style="opacity: 0.55; cursor: pointer; float: right; position: relative; top: -1px; display: none;"></div><div class="gmail_chip gmail_drive_chip" style="width:396px;height:18px;max-height:18px;padding:5px;color:rgb(34,34,34);font-family:arial;font-style:normal;font-weight:bold;font-size:13px;border:1px solid rgb(221,221,221);line-height:1;background-color:rgb(245,245,245)"><a href="https://drive.google.com/file/d/0B_DYTA-i186ZSUFOVmk0cko0R3M/view?usp=drive_web" target="_blank" style="display:inline-block;max-width:366px;overflow:hidden;text-overflow:ellipsis;white-space:nowrap;text-decoration:none;padding:1px 0;border:none"><img style="vertical-align: bottom; border: none;" src="https://ssl.gstatic.com/docs/doclist/images/icon_10_generic_list.png"> <span dir="ltr" style="color:rgb(17,85,204);text-decoration:none;vertical-align:bottom">PhantomBox.raw</span></a><img src="//ssl.gstatic.com/ui/v1/icons/common/x_8px.png" style="opacity: 0.55; cursor: pointer; float: right; position: relative; top: -1px; display: none;"></div><div class="gmail_chip gmail_drive_chip" style="width:396px;height:18px;max-height:18px;background-color:#f5f5f5;padding:5px;color:#222;font-family:arial;font-style:normal;font-weight:bold;font-size:13px;border:1px solid #ddd;line-height:1"><a href="https://drive.google.com/file/d/0B_DYTA-i186ZZnBrNU9XbTVVY00/view?usp=drive_web" target="_blank" style="display:inline-block;max-width:366px;overflow:hidden;text-overflow:ellipsis;white-space:nowrap;text-decoration:none;padding:1px 0;border:none"><img style="vertical-align: bottom; border: none;" src="https://ssl.gstatic.com/docs/doclist/images/icon_10_generic_list.png"> <span dir="ltr" style="color:#15c;text-decoration:none;vertical-align:bottom">PhantomBoxRotX2.nfo</span></a><img src="//ssl.gstatic.com/ui/v1/icons/common/x_8px.png" style="display:none; opacity: 0.55; cursor: pointer; float: right; position: relative; top: -1px; "></div><div class="gmail_chip gmail_drive_chip" style="width:396px;height:18px;max-height:18px;padding:5px;color:rgb(34,34,34);font-family:arial;font-style:normal;font-weight:bold;font-size:13px;border:1px solid rgb(221,221,221);line-height:1;background-color:rgb(245,245,245)"><a href="https://drive.google.com/file/d/0B_DYTA-i186ZQmNhQkx2MzVFQXc/view?usp=drive_web" target="_blank" style="display:inline-block;max-width:366px;overflow:hidden;text-overflow:ellipsis;white-space:nowrap;text-decoration:none;padding:1px 0;border:none"><img style="vertical-align: bottom; border: none;" src="https://ssl.gstatic.com/docs/doclist/images/icon_10_generic_list.png"> <span dir="ltr" style="color:rgb(17,85,204);text-decoration:none;vertical-align:bottom">PhantomBoxRotX2.raw</span></a><img src="//ssl.gstatic.com/ui/v1/icons/common/x_8px.png" style="opacity: 0.55; cursor: pointer; float: right; position: relative; top: -1px; display: none;"></div></div></div><div class="gmail_extra"><br clear="all"><div><div class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><p>--</p><p>AH<br></p><p><br></p><p>-----------------------------------------------------------------------------------------------</p><p><i>This email and any attachments thereto may contain private, confidential, and privileged materials for the sole use of the intended recipient.

I have written an observer that outputs to a text file the iteration number, correlation value, and current position. I have generated a virtual phantom image of a white cube on a black background, and when I put the same image through for fixed and moving images, I get [0,0,0,0,0,0], meaning that no rotation or translation is required for the images to be aligned. This is the correct versor and vector transform, and if I apply a translation the correct distance values are returned to have the images align, however the metric value returned is also 0 and a perfect registration like this should yield a metric of -1 according to the documentation. Additionally, it doesn’t seem to be analyzing rotation properly, as when I introduce a rotation around any axis the metric returns a translation on the other two axes but the rotation versor remains at zero.</div><div><br></div><div>I’m attaching my code as well, it’s possible I’ve not set some parameters up properly:</div><div><br></div><div><br></div><div><div><div data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><p>--</p><p>AH<br></p><p><br></p><p>------------------------------<wbr>------------------------------<wbr>------------------------------<wbr>-----</p><p><i>This email and any attachments thereto may contain private, confidential, and privileged materials for the sole use of the intended recipient.
