plateausplateausPlateausPlateaus (Operator)
Name
plateausplateausPlateausPlateaus — Detect all gray value plateaus.
Signature
Description
plateausplateausPlateausPlateausPlateaus extracts all points from ImageImageImageImageimage with a gray value
greater or equal to the gray value of its neighbors (8-neighborhood) and
returns them in PlateausPlateausPlateausPlateausplateaus. Each maximum is returned as a separate
region.
Execution Information
- 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
ImageImageImageImageimage (input_object) singlechannelimage(-array) → objectHImageHImageHobject (byte / direction / cyclic / int1 / int2 / uint2 / int4 / int8 / real)
Input image.
PlateausPlateausPlateausPlateausplateaus (output_object) region-array → objectHRegionHRegionHobject *
Extracted plateaus as regions (one region for
each plateau).
