Dear all, <br>I wonder if any of you knows a simply way to apply a generic vector field to a point. <br>To have more insight in this: <br>I generate an artificial deformation by means of gaussians (i.e. the final vector field is a composition of 3 gaussians)<br>
I have a point in physical coordinates (A) and its correspondent point (B) on the final image (extracted via SIFT algorithm)<br>I want to transform A and check that is "close enough" to B. <br><br>The "easiest" way I thought about is the following: <br>
1) read point and vector field in<br>2) reconstruct the transform by means of interpulation ---> I mean basically I would need to interpulate the vector field for example with Bsplines because my points can be anywhere<br>
3) derive the corresponding vector that has to be applied on the point A<br>4) distance from B<br><br>I'm using itk 3.20 on win/linux :) and I would really appreciate any help :) <br>thanks<br>Marta<br>
