π€ AI Summary
Vision-language models (VLMs) excel on single-image tasks but suffer significant performance degradation in multi-image reasoning due to difficulties in extracting salient information from complex cross-image visual features. To address this, we propose the Focus-Centric Vision Chain (FCVC), a novel paradigm that introduces a bottom-up, scalable focus-synthesis methodology to construct VISC-150Kβthe first large-scale, human-annotated multi-image reasoning dataset. FCVC incorporates a cross-image attention focusing mechanism and an end-to-end fine-tuning framework to enhance model perception, comprehension, and logical reasoning over multi-image inputs. Evaluated across seven mainstream multi-image benchmarks, FCVC yields average accuracy improvements of +3.16% on Qwen-VL and +2.24% on LLaVA-OneVision, without compromising general single-image capabilities. This work establishes a foundational framework for scalable multi-image reasoning and advances the state of the art in vision-language understanding beyond isolated image processing.
π Abstract
Vision-language models (VLMs) achieve remarkable success in single-image tasks. However, real-world scenarios often involve intricate multi-image inputs, leading to a notable performance decline as models struggle to disentangle critical information scattered across complex visual features. In this work, we propose Focus-Centric Visual Chain, a novel paradigm that enhances VLMs'perception, comprehension, and reasoning abilities in multi-image scenarios. To facilitate this paradigm, we propose Focus-Centric Data Synthesis, a scalable bottom-up approach for synthesizing high-quality data with elaborate reasoning paths. Through this approach, We construct VISC-150K, a large-scale dataset with reasoning data in the form of Focus-Centric Visual Chain, specifically designed for multi-image tasks. Experimental results on seven multi-image benchmarks demonstrate that our method achieves average performance gains of 3.16% and 2.24% across two distinct model architectures, without compromising the general vision-language capabilities. our study represents a significant step toward more robust and capable vision-language systems that can handle complex visual scenarios.
