pairwise_intersection

pairwise_intersection(boxes1: Boxes, boxes2: Boxes) -> np.ndarray

• Description:

  pairwise_intersection is a function used to calculate the intersection area between two lists of bounding boxes. It computes the intersection area for all N x M pairs of bounding boxes. The input bounding boxes must be of type Boxes.

• Parameters

  • boxes1 (Boxes): The first list of bounding boxes, containing N bounding boxes.
  • boxes2 (Boxes): The second list of bounding boxes, containing M bounding boxes.

• Example

  import capybara as cb
  
  boxes1 = cb.Boxes([[10, 20, 50, 80], [20, 30, 60, 90]])
  boxes2 = cb.Boxes([[20, 30, 60, 90], [30, 40, 70, 100]])
  intersection = cb.pairwise_intersection(boxes1, boxes2)
  print(intersection)
  # >>> [[1500. 800.]
  #      [2400. 1500.]]
