reduce_domainreduce_domainReduceDomainreduce_domainReduceDomainReduceDomain (Operator)

Name

reduce_domainreduce_domainReduceDomainreduce_domainReduceDomainReduceDomain — Reduce the domain of an image.

Signature

reduce_domain(Image, Region : ImageReduced : : )

The operator reduce_domainreduce_domainReduceDomainreduce_domainReduceDomainReduceDomain reduces the definition domain of the given image to the indicated region. The new definition domain is calculated as the intersection of the old definition domain with the region. Thus, the new definition domain can be a subset of the region. The size of the matrix is not changed.

Parallelization

Supports objects on compute devices.
Multithreading type: reentrant (runs in parallel with non-exclusive operators).
Multithreading scope: global (may be called from any thread).
Automatically parallelized on tuple level.

Parameters
