[Insight-users] Displaying .mat files

[Ing. Arturo Vargas Olivares]

I'm trying to display a picture but I'm not sure why I can't.
(Commands in blue, outputs in green)

Any ideas?


*inputImage = sitk.ReadImage( 'lena_color.bmp' )*
*inputImage
Out[89]: <SimpleITK.Image; proxy of <Swig Object of type 'std::vector<
itk::simple::Image >::value_type *' at 0x0000000019BE6C60> >*
*sitk.Show( inputImage )
**
