Geometry to Region

## Geometry to Region

Generate a region in a geometric shape region of arbitrary shape, which can be used for subsequent required modules and can act as a mask

## Usage Method

1. Add this module directly, and then select the desired geometric shape, such as regular rectangle, rotated rectangle, circle, ring, sector, polygon, etc. The shadow of the geometric shape region in the figure is the generated region.
2. Region processing. After generating the region, some morphological operations can be performed on the region as needed, such as erosion, dilation, opening and closing operations, etc.
3. Support mask setting to shield or only detect certain regions.
