Evidencepartial
we introduce CIPHER (Counterfactual Image Perturbations for Hallucination Extraction and Removal), a training-free method that suppresses vision-induced hallucinations via lightweight feature-level correction.
Implicationpartial
The abstract explicitly states this as the core contribution of the paper.
Verificationpartial
partial
Evidencepartial
Unlike prior training-free approaches that primarily focus on text-induced hallucinations, CIPHER explicitly targets hallucinations arising from the visual modality.
Implicationpartial
The abstract clearly distinguishes CIPHER's focus from previous methods.
Verificationpartial
partial
Evidencepartial
In the offline phase, we construct OHC-25K (Object-Hallucinated Counterfactuals, 25,000 samples), a counterfactual dataset consisting of diffusion-edited images that intentionally contradict the original ground-truth captions.
Implicationpartial
The abstract describes the construction of the OHC-25K dataset in detail.
Verificationpartial
partial
Evidencepartial
Contrasting these representations with those from authentic (image, caption) pairs reveals structured, systematic shifts spanning a low-rank subspace characterizing vision-induced hallucination.
Implicationpartial
The abstract explains how the OHC-25K dataset is used to identify these shifts, implying this characteristic.
Verificationpartial
partial
Evidencepartial
In the inference phase, CIPHER suppresses hallucinations by projecting intermediate hidden states away from this subspace.
Implicationpartial
The abstract clearly outlines the inference phase mechanism of CIPHER.
Verificationpartial
partial
Evidencepartial
Experiments across multiple benchmarks show that CIPHER significantly reduces hallucination rates while preserving task performance, demonstrating the effectiveness of counterfactual visual perturbations for improving LVLM faithfulness.
Implicationpartial
The abstract states this as an experimental outcome.

Evidencepartial
Experiments across multiple benchmarks show that CIPHER significantly reduces hallucination rates while preserving task performance, demonstrating the effectiveness of counterfactual visual perturbations for improving LVLM faithfulness.
Implicationpartial
The abstract explicitly mentions this dual benefit of the method.
