polygon_iou

polygon_iou(poly1: Polygon, poly2: Polygon) -> float

• Description:

  polygon_iou is a function used to calculate the Intersection over Union (IoU) between two polygons. It computes the ratio of the intersection area to the union area of the two polygons. The input polygons must be of type Polygon.

• Parameters

  • poly1 (Polygon): The predicted polygon.
  • poly2 (Polygon): The ground truth polygon.

• Example

  import capybara as cb
  
  poly1 = cb.Polygon([(0, 0), (0, 1), (1, 1), (1, 0)])
  poly2 = cb.Polygon([(0.5, 0.5), (0.5, 1.5), (1.5, 1.5), (1.5, 0.5)])
  iou = cb.polygon_iou(poly1, poly2)
  print(iou)
