Hello,

Is the GPU based block matching algorithm available from this paper ?

http://www.insight-journal.org/browse/publication/876

The BlockMatchingImageFilter used seems to be multi-threaded only ?

Thank you,
David Fuentes

> Title: An ITK Implementation of Physics-based Non-rigid Registration Method
> Authors: Liu Y., Kot A., Drakopoulos F., Fedorov A., Enquobahrie A., Clatz
> O., Chrisochoides N.
> Abstract: As part of the ITK v4 project efforts, we have developed ITK
> filters for physics-based non-rigid registration (PBNRR), which satisfies
> the following requirements: account for tissue properties in the
> registration, improve accuracy compared to rigid registration, and reduce
> execution time using GPU and multi-core accelerators. The implementation
> has three main components: (1) Feature Point Selection, (2) Block Matching
> (mapped to both multi-core and GPU processors), and (3) a Robust Finite
> Element Solver. The use of multi-core and GPU accelerators in ITK v4
> provides substantial performance improvements.  For example, in average for
> the non-rigid registration of brain MRIs, the performance of the Block
> Matching filter is about 12 times faster when 12 hyperthreaded multi-cores
> are used and about 540 times faster when the Quadro 6000 with 448 threads
> is used in Dell Workstation.
