Dear Itk users,<br> <br>I'm using GeodesicActiveContourShapePriorLevelSetFilter image filter to segment 2d sagittal<br>images of vertebrae from L1 to S1. We created an average shape as described within the <br>itk programming guide using about 50 images for each vertebrae, so the segmented vertebrae<br>
were registered ,we did the pca and so on.... <br>After the training set has been created we tried the algorithm on some image, the user was<br>able to click on the vertebrae and from this seed point the segmentation started. We found that the<br>
final resul is a lot influenced by the rotation of the object to be segmented, than we modified a bit<br>our user interface so that the user could specify an initial rotation of the vertebrae to be segmented.<br>The results we got were quite good, but still there are some cases like those attached where the <br>
final segmentation is not perfectly adherent to the vertebrae border and the segmented object<br>is not perfectly rotated.<br> <br>Could you please give me some advice ?<br>Any hint would help.<br>Kind regards<br>-Loris
