PowerBoxesrs

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

Installation

cargo add powerboxesrs

Functions available

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
• tiou_distance: Compute the tracking intersection over union matrix of two sets of boxes

Rotated Box Metrics

• rotated_iou_distance: Compute the intersection over union matrix of two sets of rotated boxes in cxcywha format
• rotated_giou_distance: Compute the generalized intersection over union matrix of two sets of rotated boxes in cxcywha format

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.

Use it in Rust

See the documentation for more details. Here is a simple example:

use ndarray::array;
use powerboxesrs::boxes::box_areas;
let boxes = array![[1., 2., 3., 4.], [0., 0., 10., 10.]];
let areas = box_areas(&boxes);
assert_eq!(areas, array![4., 100.]);
