add_channelsadd_channelsAddChannelsAddChannels (Operator)

Name

add_channelsadd_channelsAddChannelsAddChannels — Add gray values to regions.

Signature

add_channels(Regions, Image : GrayRegions : : )

Description

The operator add_channelsadd_channelsAddChannelsAddChannelsAddChannels creates an array of images GrayRegionsGrayRegionsGrayRegionsGrayRegionsgrayRegions with an element for every input region in RegionsRegionsRegionsRegionsregions. These images correspond to the input image ImageImageImageImageimage 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 ImageImageImageImageimage 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.

Parameters

RegionsRegionsRegionsRegionsregions (input_object) region(-array) → object

Input regions (without pixel values).

ImageImageImageImageimage (input_object) (multichannel-)image → object (byte / direction / cyclic / int1 / int2 / uint2 / int4 / int8 / real / complex / vector_field)

Input image with pixel values for regions.

GrayRegionsGrayRegionsGrayRegionsGrayRegionsgrayRegions (output_object) image(-array) → object (byte / direction / cyclic / int1 / int2 / uint2 / int4 / int8 / real / complex / vector_field)

Output image(s) with regions and pixel values (one image per input region).

Number of elements: Regions == GrayRegions
