Hi,I have noticed that when using mitk::ImageToSurfaceFilter on a binary image, the surface produced by the vtkMarchingCubes class involved in this filter (using the value "0" for contouring) generates a surface not representing the outline of the segmentation. This can inherit from the interpolation of the values of the resulting surface along the boundary, which are mapped to integer values after calculation. A solution for binary images would be to set all "0" values in the binary image to -1 and run vtkMarchingCubes with the contouring value of "0" (the median of "-1" and "1"). Anyhow, the complete mitk::ImageToSurfaceFillter seems to converge against an original surface very fast, when considering increasing image resolutions.
