New TMAL method improves curvilinear structure segmentation

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new method called Topology-preserving Multi-offset Affinity Learning (TMAL) for segmenting curvilinear structures like retinal vessels and surface cracks. TMAL addresses limitations in existing pixel-wise and connectivity-based approaches by using soft affinities that emphasize thin regions and predict directional affinities at multiple offsets. This allows for better modeling of connections between pixels, even at larger distances. The method also incorporates region-level supervision to maintain high overlap accuracy. TMAL has demonstrated superior performance on the DRIVE and DeepCrack datasets, achieving the highest scores in Dice, IoU, and clDice, while significantly reducing connected-component errors. AI

IMPACT This research offers improved accuracy for segmenting complex structures in medical imaging and material analysis.

    TMAL: Topology-preserving Multi-offset Affinity Learning for Curvilinear Structure Segmentation

    arXiv:2611.13511v1 Announce Type: new Abstract: Curvilinear structures such as retinal vessels and surface cracks need both pixel-level accuracy and structural continuity. Pixel-wise supervision does not model the connections between pixels, and topology-based losses still produc…
