Redefining Instance Matching: A Unified Framework for Part-Aware Matching in Panoptic Segmentation Evaluation
arXiv:2605.31094v1 Announce Type: cross Abstract: The Panoptic Quality (PQ) metric is the standard for jointly evaluating instance and semantic segmentation. However, its original definition relies on a One-to-One matching between predicted and ground truth segments, which is only straightforward when the IoU threshold exceeds 0.5. Below 0.5, multiple matching strategies emerge in a poorly explored problem space. We systematically elucidate this space by recasting segment matching as a constrained bipartite assignment problem. Independently bounding the prediction- and ground-truth-side degree
The continuous evolution of AI, particularly in computer vision and segmentation, necessitates more robust and accurate evaluation metrics to advance the field beyond current limitations.
Improved evaluation metrics for panoptic segmentation enable the development of more reliable and precise AI models, crucial for applications in robotics, autonomous systems, and advanced analytics.
The proposed unified framework refines the fundamental understanding of instance matching in panoptic segmentation, potentially leading to more accurate and widely applicable AI vision systems.
