WebSep 18, 2024 · direction = identity matrix dimensions = (256, 256, 208) From my understanding, when loading an image file in SimpleITK, it converts it to LPS format, meaning that subsequent calls to the GetOrigin and GetDirection functions should be returning these values: origin = (127, 158, -110) direction = (-1, 0, 0; 0, -1, 0; 0, 0, 1) WebSimpleITK supports two types of bounded non-rigid transformations, BSplineTransform (sparse representation) and DisplacementFieldTransform (dense representation). Transforming a point that is outside the bounds will return the original point - identity transform. BSpline ¶ Using a sparse set of control points to control a free form deformation.
