select_shape_stdselect_shape_stdSelectShapeStdSelectShapeStd (Operator)

Name

select_shape_stdselect_shape_stdSelectShapeStdSelectShapeStd — Select regions of a given shape.

Signature

Description

The operator select_shape_stdselect_shape_stdSelectShapeStdSelectShapeStdSelectShapeStd 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 ShapeShapeShapeShapeshape are:

'max_area'

The largest region is selected.

'rectangle1'

The surrounding rectangle parallel to the coordinate axes is determined via the operator smallest_rectangle1smallest_rectangle1SmallestRectangle1SmallestRectangle1SmallestRectangle1. If the area difference in percent is larger than PercentPercentPercentPercentpercent the region is adopted.

'rectangle2'

The smallest surrounding rectangle with any orientation is determined via the operator smallest_rectangle2smallest_rectangle2SmallestRectangle2SmallestRectangle2SmallestRectangle2. If the area difference in percent is larger than PercentPercentPercentPercentpercent the region is adopted. Note that as a more robust alternative the operator select_shapeselect_shapeSelectShapeSelectShapeSelectShape with FeatureFeatureFeatureFeaturefeature set to 'rectangularity'"rectangularity""rectangularity""rectangularity""rectangularity" can be used instead.
