<p>Update from Wiki</p> <p><b>New page</b></p><div>== ITK Affine Invariant Anisotropic Smoothing Image Filter ==<br /> <br /> [[Media:2006_AHM_Programming_Half_Week_Affine_Invariant_Smoothing.ppt|Link to Project 4-Block Summary]]<br /> <br /> ==== Introduction ====<br /> <br /> This ITK filter is an affine-invarient anisotropic smoothing filter.<br /> <br /> ==== Background Reading ====<br /> <br /> PJ Olver, G Sapiro, A Tannenbaum. &quot;Invariant geometric evolutions of surfaces and volumetric smoothing.&quot; 1994.<br /> <br /> ==== Use Case ====<br /> <br /> I'd like to remove noise from an image while preserving edges and I would like the result to be invariant to an affine transformation. This means that if I take an image and its sheared version, and I apply the filter to both images, I should get the same result when I compare the original smoothed image and the smooth sheared image after it is unsheared.<br /> <br /> ==== Initial Status before Programming Week (jan 2006) ====<br /> <br /> * implemented in Matlab<br /> <br /> ==== Current Status after Programming Week (jan 2006) ====<br /> <br /> * Implemented itkAffineInvariantCurvatureFlowImageFilter.h/.txx (in Code/Algorithms) as well as AffineInvariantCurvatureFlowImageFilter.cxx example (in Examples/Filtering)<br /> * checked in to the sandbox under AffineInvariantCurvatureFlow<br /> <br /> ==== Remaining Work ====<br /> <br /> * Restrict the filter to 2D<br /> * Write and submit Insight journal<br /> * Test the code on a sheared image to demonstrate the effect of affine invariance<br /> <br /> ==== People ====<br /> <br /> ===== Core 1 Team =====<br /> <br /> [[User:Melonakos|John Melonakos]] - Georgia Tech &lt;br /&gt; Delphine Nain - Georgia Tech &lt;br /&gt;<br /> <br /> ===== Core 2 Team =====<br /> <br /> Jim Miller (GE)</div>
