Grid2Matrix: Revealing Digital Agnosia in Vision-Language Models

Researchers introduce Grid2Matrix, a benchmark that reveals fundamental limitations in Vision-Language Models' ability to accurately process and describe visual details in grids. The study identifies a critical gap called 'Digital Agnosia'—where visual encoders preserve grid information that fails to translate into accurate language outputs—suggesting that VLM failures stem not from poor vision encoding but from the disconnection between visual features and linguistic expression.

InterChart: Benchmarking Visual Reasoning Across Decomposed and Distributed Chart Information

Researchers introduce InterChart, a benchmark designed to evaluate how well vision-language models (VLMs) reason across multiple related charts—a capability essential for financial analysis, scientific reporting, and policy dashboards. Testing reveals that state-of-the-art VLMs struggle significantly as chart complexity increases, performing better when multi-entity charts are decomposed into simpler components, highlighting a critical gap in multimodal reasoning capabilities.

Lost in Space? Vision-Language Models Struggle with Relative Camera Pose Estimation

Researchers find that vision-language models (VLMs) significantly underperform on relative camera pose estimation tasks, achieving only 66% accuracy compared to humans (91%) and specialized pipelines (99%). The study identifies specific gaps in multi-view spatial reasoning, including cross-view correspondence and projective camera-motion understanding, revealing concrete limitations in VLM capabilities beyond single-image tasks.

VANGUARD: Vehicle-Anchored Ground Sample Distance Estimation for UAVs in GPS-Denied Environments

Researchers developed VANGUARD, a deterministic tool that helps autonomous drones estimate ground sample distance in GPS-denied environments by using vehicles as reference points. The system addresses critical safety issues with AI vision models that showed over 50% errors in spatial scale estimation, achieving 6.87% median error on benchmark tests.
