Testing the Test: Score-Direction Instability in Class-Split Anomaly Detection

Alejandro Ascarate, Leo Lebrat, Rodrigo Santa Cruz +2

Within-dataset class-split evaluation is widely used as a proxy for fully unconditional out-of-distribution anomaly detection. We show that this protocol can become ill-posed when…

High-Dimensional Latents Should Be Diagnosed Through Phase Structure

Alejandro Ascarate, Leo Lebrat, Rodrigo Santa Cruz +2

We study autoencoder and variational-autoencoder latent spaces through the lens of spin-glass theory. The paper has two components. First, we formalize a latent-space spin-glass di…

When Rule Violations Are Rare: Chimera Training for Logical Anomaly Detection

Alejandro Ascarate, Leo Lebrat, Rodrigo Santa Cruz +2

Many practical anomalies are not merely rare inputs, but violations of semantic constraints: objects co-occur in structured ways, actions imply preconditions, and events satisfy te…

NC-Reg : Neural Cortical Maps for Rigid Registration

Ines Vati, Pierrick Bourgeat, Rodrigo Santa Cruz +4

We introduce neural cortical maps, a continuous and compact neural representation for cortical feature maps, as an alternative to traditional discrete structures such as grids and…

Non-Invasive 3D Wound Measurement with RGB-D Imaging

Lena Harkämper, Leo Lebrat, David Ahmedt-Aristizabal +3

Chronic wound monitoring and management require accurate and efficient wound measurement methods. This paper presents a fast, non-invasive 3D wound measurement algorithm based on R…

Multi-View Consistent Wound Segmentation With Neural Fields

Remi Chierchia, Léo Lebrat, David Ahmedt-Aristizabal +4

Wound care is often challenged by the economic and logistical burdens that consistently afflict patients and hospitals worldwide. In recent decades, healthcare professionals have s…
