Common-Witness Certificates and Sharp Feature Bounds for Counterfactual Image Auditing

The paper introduces a framework for auditing image editors that can satisfy regional plausibility constraints while lacking a single latent explanation for the entire output. It defines a common witness grade and witness nerve to formalize local-to-global failures, separating auditing from causal identification. Using Helly-type arguments and a blocker-hypergraph formula, the authors provide short incompatibility certificates, sharp partial-identification bounds for specified image features, and finite-sample outer coverage of identified intervals, validated through controlled MNIST, Morpho-MNIST, and smallNORB experiments.

SafeRestore: Detector-Relative Risk Certificates for Selective Industrial Image Restoration

SafeRestore introduces a framework for certifying when an industrial image restoration should be automatically returned to a detector or require human review. It ranks five restoration candidates using action‑specific fitted scores, selects a threshold gate on tuning data, and evaluates the gate on a separate certification sample with two one‑sided exact binomial bounds—one for evidence‑loss incidents and one for excess‑activation incidents. In a retrospective study of 4,591 Carinthia‑S images, the protocol demonstrates auditable risk‑coverage behavior, with varying pass rates across different policies and morphologies.

Do Vision Models Learn Physical Constraints or Rendering Shortcuts? A Counterfactual Benchmark for Grounded Physical Consistency

The paper introduces a counterfactual benchmark to evaluate whether vision models understand physical constraints or merely learn rendering shortcuts. Using Mitsuba 3, it generates 5,500 synthetic images across 500 scene families, each with a clean image and ten violations (shadows, reflections, support, surface response, occlusion). Diagnostic baselines (LLaVA‑1.5‑7B, Qwen2.5‑VL‑7B, InternVL3.5‑8B) achieve 64.0–67.8 % macro‑F1 on a held‑out synthetic test set, but performance drops to 40.8 % for LLaVA‑1.5‑7B under an intervention shift, indicating reliance on rendering cues rather than true physical reasoning.

Hold-Out Self-Validation Cannot Certify Photogrammetric Accuracy: Saturation and Blindness to Coherent Distortion

The paper argues that internal self-consistency checks cannot guarantee the accuracy of photogrammetric reconstructions, a limitation that is structural rather than a tuning issue. It introduces a track‑leakage‑free hold‑out protocol that withholds a deterministic subset of images and tests each against only 3D points supported by at least two retained images, ensuring no view is evaluated against the structure it helped create. Experiments on diverse datasets show that while the protocol is well‑posed, it saturates at a confidence score of 1.00 and fails to detect coherent distortion, missing large errors that can reach over 100 m. whyItMatters":"The study highlights that hold‑out self‑validation scores, increasingly used as quality evidence for metric deliverables, may be misleading and cannot replace external survey validation."

EviDent-CBCT: Evidence-Bottlenecked Report Generation from Dental CBCT under Non-Exhaustive Report Supervision

EviDent-CBCT is a framework that generates dental cone‑beam CT reports from limited clinical data by first extracting a discrete record of tooth‑level, global, and tooth‑IAC evidence using an anatomy‑aware network. The evidence is reconciled through a dental‑logic consistency projection before being rendered into a report by a deterministic renderer and an image‑blind language model. The system achieves higher evidence set‑F1 and logical‑F1 scores than baselines and ranked highly in the ODIN 2026 challenge, demonstrating the effectiveness of a discrete evidence record for auditable CBCT report generation.
