[Insight-users] ImageSeriesReader memory allocation for large datasets

[Marius Erdt]

Hello,

I'm getting the following memory allocation error together with the 
itk::ImageSeriesReader when loading series of png images:

d:\itk\src\insighttoolkit-3.4.0\code\common\itkImportImageContainer.txx:188:
Failed to allocate memory for image.

However, the data (about 1000 slices of 16Bit png or ~560 Mb) should fit 
into main memory (4Gbyte). Since the data is just loaded, the Windows 
data allocation limit for a single process should also not be the problem.

I'm experiencing this behavior not just for png images but for all big 
datasets I want to load with itk. Does anyone know what exactly the 
problem is or how to load such big data sets with itk?

Thanks for help,
Marius
