[Insight-users] Memory issue

[Arunachalam Kana]

Hi ITK Users,



Situation: I have 32Gb unsigned short image and I use a 64bit machine, with linux, and my RAM size is 64Gb. I would like to apply the following itk algorithm:

Step1: Original image -> Anisotropic diffusion image filter -> smoothed image



Step 2: Own filter: I calculate the hessian for the input image. I use the hessian image and the input image to segment and produce an output image.

Smoothed image -> hessianrecurssivegaussianimagefilter-> smoothed image + hessian image ->segmentation function -> segmented image



Step 3: Segmented image -> 3dbinarythinning -> thinned image.



After every step the output image will be save to local hard disk.



Questions:

1.       Will there be any memory problem in application of anisotropic diffusion filter, hessian filter and 3dbinarythinning?

2.       If the answer is yes to the above question. How can i solve it?

Thank you,

Regards,
