This research exposes a critical vulnerability in Large Visual Language Models where decorative text styling leaks into semantic inference, altering attribute descriptions even when the underlying concept is correctly identified. The findings underscore the necessity for style-aware evaluation and mitigation strategies to ensure robustness in LVLM-based multimedia systems against non-functional visual noise.
Revealing the Impact of Visual Text Style on Attribute-based Descriptions Produced by Large Visual Language Models
arXiv:2604.27553v1 Announce Type: cross Abstract: When the visual style of text is considered, a wide variety can be observed in font, color, and size. However, when a word is read, its meaning is independent of the style in which it has been written or rendered. In this paper, we investigate whether, and how, the style in which a word is visualized in an image impacts the description that a Large Visual Language Model (LVLM) provides for the concept to which that word refers. Specifically, we investigate how functional text styles (readability-oriented, e.g., black sans-serif) versus decorative styles (display-oriented, e.g., colored cursive/script) affect LVLMs' descriptions of a concept in terms of the attributes of that concept. Our experiments study the situation in which the LVLM is able to correctly identify the concept referred to by a visual text, i.e., by a word or words rendered as an image, and in which the visual text style should not influence the attribute-based description that the LVLM produces. Our experimental results reveal that even when the concept is correctly identified, text style influences the model's attribute-based descriptions of the concept. Our findings demonstrate non-trivial style leakage from text style into semantic inference and motivate style-aware evaluation and mitigation for LVLM-based multimedia systems.
