[Insight-users] Failed to allocate memory for image

[Luis Ibanez]

Hi Ming,


What tool did you used for monitoring the memory usage ?


What was the memory usage for the entire machine ?
(you only reported the usage for the registration application).

Do you have other applications running at the same time that
your are running the registration application ?


In Windows 32 bits, a process can only access 2Gb of contiguous
RAM.

What Image Metric are you using ?
(e.g. is it one of the metrics that computes the image gradient?)


What other ITK and/or VTK filter do you have in that pipeline.


At what point in the execution of your program do you get this
message ?


Have the registration started ?
Do you got some optimization iterations ?


It is very likely that you are actually using most of those
2Gb of data, and may have to release memory as your appllication
progresses with its pipeline.



   Please let us know what you find.


      Thanks



         Luis
