Module verify 

COCO dataset verification utilities.

Provides functions for comparing COCO datasets and validating annotation accuracy using Hungarian matching for optimal annotation pairing.

Structs

BboxValidationResult

Bounding box validation results.

CategoryValidationResult

Category validation results.

MaskValidationResult

Segmentation mask validation results.

SegmentationPairComparison

Result of comparing a single segmentation pair.

VerificationResult

Result of verifying a COCO import against Studio data.

Functions

bbox_iou

Calculate Intersection over Union (IoU) for two COCO bboxes. COCO bbox format: [x, y, width, height] (top-left corner)

build_annotation_map_by_name

Build a map of annotations by sample name for efficient lookup.

compare_segmentation_pair

Compare two segmentations and return comparison metrics.

compute_segmentation_area

Calculate total area of a segmentation.

count_polygon_parts

Count number of polygon parts in a segmentation.

count_polygon_vertices

Count total polygon vertices in a segmentation.

hungarian_match

Use Hungarian algorithm to find optimal matching between two sets of annotations based on bounding box IoU. Returns pairs of (original_idx, restored_idx) for matched annotations.

polygon_area

Calculate polygon area using the Shoelace formula. Takes coordinates as flat array [x1, y1, x2, y2, …]

polygon_bounds

Calculate bounding box of a polygon (min_x, min_y, max_x, max_y)

segmentation_bbox_iou

Calculate IoU between two segmentation bounding boxes.

segmentation_bounds

Get bounding box for any segmentation type.

validate_bboxes

Validate bounding boxes between two datasets using Hungarian matching.

validate_categories

Validate categories between two datasets.

validate_masks

Validate segmentation masks between two datasets using Hungarian matching.
