add_channelsadd_channelsAddChannelsAddChannelsadd_channels (Operator)
Name
add_channelsadd_channelsAddChannelsAddChannelsadd_channels
— Add gray values to regions.
Signature
def add_channels(regions: HObject, image: HObject) -> HObject
Description
The operator add_channelsadd_channelsAddChannelsAddChannelsAddChannelsadd_channels
creates an array of images
GrayRegionsGrayRegionsGrayRegionsGrayRegionsgrayRegionsgray_regions
with an element for every input region in
RegionsRegionsRegionsRegionsregionsregions
. These images correspond to the input image ImageImageImageImageimageimage
with a reduced domain, namely the intersection of the definition domain of
the input image with the region.
Thus, the new definition domain can be a subset of the region.
Thereby the size of the image matrix is not changed and all channels of
ImageImageImageImageimageimage
are adopted.
Execution Information
- 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.
