Description
In order to support radial neighborhoods in the noise reduction plugins we had to rely on a SerialImageAssignment. We should be able to use a parallel version if we redefine how we do things.
One issue is the call to space.copy() in the input iterator initialization code. This is necessary but causes issues with anchor point consistency (i.e. testing WithinRadiusOfPointConditions). A possible workaround is to define a new input iterator that deals with Tuple2<long[],long[]> representing input point and neighborhood anchor point. Then parallelization would likely work fine.

ImgLib2 OPS is retired in favor of ImageJ OPS. It has its own "chunker" API for parallelization that likely does not suffer from this problem.
