Powerboxes is a package containing utility functions for transforming bounding boxes and computing metrics from them.

§Powerboxesrs

powerboxesrs is a Rust package containing utility functions for transforming bounding boxes and computing metrics from them.

§Installation

Add the following to your Cargo.toml file:

[dependencies]
powerboxesrs = "0.2.3"

§Usage

use ndarray::array;
use powerboxesrs::iou::iou_distance;

let boxes1 = array![[0.0, 0.0, 1.0, 1.0], [2.0, 2.0, 3.0, 3.0]];
let boxes2 = array![[0.5, 0.5, 1.5, 1.5], [2.5, 2.5, 3.5, 3.5]];
let iou = iou_distance(&boxes1, &boxes2);
assert_eq!(iou, array![[0.8571428571428572, 1.],[1., 0.8571428571428572]]);

§Functions available

warning: all functions expect the boxes to be in the format xyxy (top left and bottom right corners) (not box conversion functions, of course)

§Box Transformations and utilities
  • box_areas: Compute the area of list of boxes
  • box_convert: Convert a box from one format to another. Supported formats are xyxy, xywh, cxcywh.
  • remove_small_boxes: Remove boxes with area smaller than a threshold
  • mask_to_boxes: Convert a mask to a list of boxes
§Box Metrics
  • iou_distance: Compute the intersection over union matrix of two sets of boxes
  • parallel_iou_distance: Compute the intersection over union matrix of two sets of boxes in parallel
  • giou_distance: Compute the generalized intersection over union matrix of two sets of boxes
  • parallel_giou_distance: Compute the generalized intersection over union matrix of two sets of boxes in parallel
§Box NMS
  • nms: Non-maximum suppression, returns the indices of the boxes to keep
  • rtree_nms: Non-maximum suppression, returns the indices of the boxes to keep, uses a r-tree internally to avoid quadratic complexity, useful when having many boxes.
