[Insight-users] Failed to allocate memory on Registration

[Fischer, Sven]

Dear all,

 

I want to do a Registration between MRT and CT image. I use Mattes
Mutual Information and a Multi resolution registration. My images have
9011200 and 181665792. Pixel Type is signed short. Doing the
registration I get the Failed to allocate memory error.

 

itk::ExceptionObject (0180F850)

Location: "float *__thiscall itk::ImportImageContainer<unsigned
long,float>::All

ocateElements(unsigned long) const"

File:
c:\src\openmaf\libraries\itk\sources\insighttoolkit-3.2.0\code\common\it
kI

mportImageContainer.txx

Line: 188

Description: Failed to allocate memory for image.

 

So I would like to know if there is a filter I can use to scale down the
memory usage of the bigger image. I think I could use the
ShrinkImageFilter for that, but I want to keep the origin of my image. I
appreciate for any suggestion that could help.

 

Cheers,

Sven
