Name
select_shape_stdselect_shape_stdSelectShapeStdselect_shape_stdSelectShapeStdSelectShapeStd — Select regions of a given shape.
The operator select_shape_stdselect_shape_stdSelectShapeStdselect_shape_stdSelectShapeStdSelectShapeStd compares the shape of the given
regions with default shapes. If the region has a similar shape it
is adopted into the output.
Possible values for ShapeShapeShapeShapeShapeshape are:
- 'max_area'
The largest region is selected.
- 'rectangle1'
The surrounding rectangle parallel to the coordinate axes is
determined via the operator smallest_rectangle1smallest_rectangle1SmallestRectangle1smallest_rectangle1SmallestRectangle1SmallestRectangle1. If the
area difference in percent
is larger than PercentPercentPercentPercentPercentpercent the region is adopted.
- 'rectangle2'
The smallest surrounding rectangle with any orientation is
determined via the operator smallest_rectangle2smallest_rectangle2SmallestRectangle2smallest_rectangle2SmallestRectangle2SmallestRectangle2. If the
area difference in percent
is larger than PercentPercentPercentPercentPercentpercent the region is adopted. Note that as a more
robust alternative the operator select_shapeselect_shapeSelectShapeselect_shapeSelectShapeSelectShape with FeatureFeatureFeatureFeatureFeaturefeature
set to 'rectangularity'"rectangularity""rectangularity""rectangularity""rectangularity""rectangularity" can be used instead.
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
