When exploring the development of Artificial General Intelligence (AGI), a
critical task for these models involves interpreting and processing information
from multiple image inputs. However, Large Multimodal Models (LMMs) encounter
two issues in such scenarios: (1) a lack of fine-grained perception, and (2) a
tendency to blend information across multiple images. We first extensively
investigate the capability of LMMs to perceive fine-grained visual details when
dealing with multiple input images. The research focuses on two aspects: first,
image-to-image matching (to evaluate whether LMMs can effectively reason and
pair relevant images), and second, multi-image-to-text matching (to assess
whether LMMs can accurately capture and summarize detailed image information).
We conduct evaluations on a range of both open-source and closed-source large
models, including GPT-4V, Gemini, OpenFlamingo, and MMICL. To enhance model
performance, we further develop a Contrastive Chain-of-Thought (CoCoT)
prompting approach based on multi-input multimodal models. This method requires
LMMs to compare the similarities and differences among multiple image inputs,
and then guide the models to answer detailed questions about multi-image inputs
based on the identified similarities and differences. Our experimental results
showcase CoCoT's proficiency in enhancing the multi-image comprehension
capabilities of large multimodal models.

当探索人工通用智能（AGI）的发展时，大型多模态模型（LMMs）在处理多个图像输入的信息时面临两个问题：细粒度感知的缺乏和融合多个图像的倾向。我们首先广泛研究了 LMMs 在处理多个输入图像时感知细粒度视觉细节的能力。研究集中在两个方面：首先，图像与图像匹配（评估 LMMs 是否能够有效推理和配对相关图像），其次，多图像与文本匹配（评估 LMMs 是否能够准确捕捉和总结详细的图像信息）。我们对一系列开源和闭源的大型模型进行评估，包括 GPT-4V，Gemini，OpenFlamingo 和 MMICL。为了增强模型性能，我们还基于多输入多模态模型开发了一种对比的思维链（CoCoT）启发方法。该方法要求 LMMs 比较多个图像输入的相似性和差异性，然后根据确定的相似性和差异性指导模型回答关于多图像输入的详细问题。我们的实验结果展示了 CoCoT 在增强大型多模态模型的多图像理解能力方面的熟练度。
