<p class=MsoNormal>Hi itkusers,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal><span lang=EN-GB>I have cylinder which can be oriented in any
angle in 3D space. I calculate the direction of cylinder using hessian and
eigen value analysis.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-GB>My goal is to draw the intensity profile of
the plane perpendicular to the cylinder direction. The size of the plane is 30

<p class=MsoNormal><span lang=EN-GB>Point (point for which the hessian is
calculate) as center. <o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-GB><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-GB>My pipeline is as follows: Read image ->
cast image to float -> calculate second derivatives ->create hessian
matrix ->calculate eigen values and vector.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-GB><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-GB>So now i have one vector showing the
direction of cylinder (called normal) and the other two orthogonal to it
(called ortho_1 and ortho_2). Till this point <o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-GB>I am clear. <o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-GB>As my goal is to extract the plane which is
formed by ortho_1 and ortho_2 and of size 30x30, i decided to do the following:<o:p></o:p></span></p>
