摘要:

最近视觉语言模型(VLMs)的进展显著推动了视觉问答(VQA)的边界。然而,高分辨率细节有时会成为噪声,导致幻觉或推理错误。本文提出退化驱动提示(DDP),一种新的框架,通过战略性地减少图像保真度来提高VQA性能。我们评估了DDP在两个不同任务上的表现。物理属性任务针对易被人类误判的图像,DDP结合80p降采样、结构视觉辅助(白背景遮罩和正交线)和上下文学习(ICL)来校准模型的焦点。感知现象任务处理各种对机器敏感的视觉异常和错觉,包括视觉异常(VA)、颜色(CI)、运动(MI)、格式(GI)、几何(GSI)和视觉错觉(VI)。对于此任务,DDP整合了任务分类阶段和专用工具如模糊遮罩和对比度增强。我们的实验结果表明,少即是多:通过有意退化视觉输入并提供针对性的结构提示,DDP使VLMs能够绕过干扰纹理,在具有挑战性的视觉基准上实现更优的推理准确性。

英文摘要:

Recent advancements in Vision-Language Models (VLMs) have significantly pushed the boundaries of Visual Question Answering (VQA).However,high-resolution details can sometimes become noise that leads to hallucinations or reasoning errors. In this paper,we propose Degradation-Driven Prompting (DDP), a novel framework that improves VQA performance by strategically reducing image fidelity to force models to focus on essential structural information. We evaluate DDP across two distinct tasks. Physical attributes targets images prone to human misjudgment, where DDP employs a combination of 80p downsampling, structural visual aids (white background masks and orthometric lines), and In-Context Learning (ICL) to calibrate the model's focus. Perceptual phenomena addresses various machine-susceptible visual anomalies and illusions, including Visual Anomaly (VA), Color (CI), Motion(MI),Gestalt (GI), Geometric (GSI), and Visual Illusions (VI).For this task, DDP integrates a task-classification stage with specialized tools such as blur masks and contrast enhancement alongside downsampling. Our experimental results demonstrate that less is more: by intentionally degrading visual inputs and providing targeted structural prompts, DDP enables VLMs to bypass distracting textures and achieve superior reasoning accuracy on challenging visual benchmarks.
