Select regions of a given shape.
The operator select_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 Shape are:
'max_area' The largest region is selected.
'rectangle1' The surrounding rectangle parallel to the coordinate axes is
determined via the operator smallest_rectangle1. If
the area difference in percent is larger than Percent
the region is adopted.
'rectangle2' The smallest surrounding rectangle with any orientation is
determined via the operator smallest_rectangle2. If
the area difference in percent is larger than Percent
the region is adopted.
