select_shape_stdselect_shape_stdSelectShapeStdSelectShapeStdselect_shape_std (算子名称)
名称
select_shape_stdselect_shape_stdSelectShapeStdSelectShapeStdselect_shape_std — Select regions of a given shape.
参数签名
def select_shape_std(区域: HObject, shape: str, percent: float) -> HObject
描述
该算子 select_shape_stdselect_shape_stdSelectShapeStdSelectShapeStdSelectShapeStdselect_shape_std 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 该算子 smallest_rectangle1smallest_rectangle1SmallestRectangle1SmallestRectangle1SmallestRectangle1smallest_rectangle1. 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 该算子 smallest_rectangle2smallest_rectangle2SmallestRectangle2SmallestRectangle2SmallestRectangle2smallest_rectangle2. If the
area difference in percent
is larger than PercentPercentPercentPercentpercentpercent the region is adopted. Note that as a more
robust alternative 该算子 select_shapeselect_shapeSelectShapeSelectShapeSelectShapeselect_shape with FeatureFeatureFeatureFeaturefeaturefeature
set to 'rectangularity'"rectangularity""rectangularity""rectangularity""rectangularity""rectangularity" can be used instead.
