This program runs the non-rigid registration of an perfusion image series.In each pass, first an ICA analysis is run to estimate and eliminate the periodic movement and create reference images with intensities similar to the corresponding original image. Then non-rigid registration is run using the an "ssd + divcurl" cost model. The B-spline c-rate and the divcurl cost weight are changed in each pass according to given parameters.In the first pass a bounding box around the LV myocardium may be extractedto speed up computation Special note to this implemnentation: the registration is always run from the original images to avoid the accumulation of interpolation errors.

FastICA implementationto be used. For supported plug-ins see Plugin type: fastica/implementation
ICA components 0 = automatic estimation
don't normalized ICs
don't strip the mean from the mixing curves
segment and scale the crop box around the LV (0=no segmentation)
skip images at the beginning of the series e.g. because as they are of other modalities
maximum number of iterations in ICA

| delta-feature: | difference of the feature images |
| features: | feature images |

Maxiumum number of threads to use for processing,This number should be lower or equal to the number of logical processor cores in the machine. (-1: automatic estimation).
Register the perfusion series given in 'segment.set' by using automatic ICA estimation. Skip two images at the beginning and otherwiese use the default parameters. Store the result in 'registered.set'.
