[Insight-users] Reading a series of images and then segmenting one image at a time

[Uday Kurkure]

Hello Ken,

Best is add try-catch to your code as Luis suggested.
The possible causes I can think of
- The filenames are not generated correctly.
- The path to the files is not correct.
- If reading only single image, better to use
ImageReader rather than ImageSeriesReader
(DicomSeriesReadImageWrite.cxx)
