[ITK-users] Failed to allocate memory for image

[Jim Miller]

Each of Abdelkhalek's volumes are 180 MB if kept as shorts.  How much memory is needed depends on the types and sequences of filters.  If a filter switches to processing floats (diffusion) or vectors (gradients), then the memory will needs escalate. Most filters needs two buffers - an input and output. Some need intermediate and temporary buffers. Filters like Watershed can need a lot of internal storage. 

If you have a long pipeline of filters, you should investigate the methods to release memory after a filter executes, such as ReleaseDataFlagOn().  You can also use scoping and DIsconnectPipeline() to force individual filters to release resources.
