[Insight-developers] Registration using a Hard Disk

[Luis Ibanez]

Hi,

This is from IEEE Computer, June 2001:
"Active Disks for Large-Scale Data Processing"

It happens that perihelial devices are smarter
and smarter, and some of them have the computing
power of PC's some years ago.

Typical hard disks today have an internal memory
of 2MB and a processor at 100Mhz, which most of
the time is sleeping...

This devices can be programmed to do some useful
things, like medical image registration.   The
more disks you put in your system the more computing
power is available (one reason for having 4 disks
of 10Gb instead of one of 40Gb  :-) ).

An application is shown using 10 disks for registering
a 384Kb image using FFT. The nicest part is that in
this way a hard disk could be integrated in a data
pipeline just as a filter more.


Luis
