[Insight-users] Stream VectorGradientMagnitudeImageFilter

[Bradley Lowekamp]

Hello Kevin,

I am able to reproduce you problem, I ran out of memory on 64GB workstation :(

I see the issue in the code now. Could you please report this issue into the mantis bug tracker and assign it to me.

Glad to see some one else trying to utilize streaming. You'll be able to process the whole Visible Woman data on you laptop with this approach.

Thanks,
Brad
