Modular Pipelines vs End-to-End VLMs

[D] Reasoning over images and videos: modular pipelines vs end-to-end VLMs

Exploring the best approach for reasoning over images and videos, the discussion contrasts modular pipelines with end-to-end Vision-Language Models (VLMs). While end-to-end VLMs show impressive capabilities, they often struggle with brittleness in complex tasks. A modular setup is proposed, where specialized vision models handle perception tasks like detection and tracking, and a Language Model (LLM) reasons over structured outputs. This approach aims to improve tasks such as event-based counting in traffic videos, tracking state changes, and grounding explanations to specific objects, while avoiding hallucinated references. The tradeoff between these methods is examined, questioning where modular pipelines excel and what reasoning tasks remain challenging for current video models. This matters because improving how machines interpret and reason over visual data can significantly enhance applications in areas like autonomous driving, surveillance, and multimedia analysis.

The discussion centers around the challenges and potential solutions for reasoning over images and videos, particularly when moving beyond single-frame understanding. While end-to-end Vision-Language Models (VLMs) have shown impressive capabilities, they often exhibit brittleness when applied to complex tasks such as event-based counting in traffic videos or tracking state changes over time. This has led to the exploration of a more modular approach, where specialized vision models handle perception tasks like detection and tracking, and a Language Model (LLM) processes the structured outputs to perform reasoning. This approach aims to mitigate the limitations of end-to-end VLMs by leveraging the strengths of individual components in a pipeline.

One of the key advantages of a modular pipeline is its ability to provide more reliable and interpretable results. By using specialized models for specific perception tasks, the system can achieve higher accuracy and robustness in detecting and tracking objects. The structured outputs generated by these models can then be fed into an LLM, which can reason over the data to provide explanations linked to specific detected objects, reducing the risk of hallucinated references that can occur when working directly with raw pixel data. This separation of perception and reasoning tasks allows for more precise control over each component, potentially leading to better performance in complex reasoning tasks.

Despite these advantages, there are still challenges to be addressed in the modular approach. One of the main issues is the integration between the perception models and the LLM, which requires careful design to ensure seamless communication and data flow. Additionally, some reasoning tasks may still be poorly handled by current video models, highlighting the need for further research and development in this area. The tradeoff between modular pipelines and end-to-end VLMs is an ongoing topic of interest, with each approach offering unique benefits and limitations depending on the specific application and task requirements.

The exploration of modular pipelines versus end-to-end VLMs raises important questions about the future of image and video reasoning. As technology continues to advance, it will be crucial to determine the most effective ways to combine perception and reasoning capabilities to achieve optimal performance. Whether LLMs will serve as a post-hoc reasoning layer or become more tightly integrated into the perception process remains to be seen. The development of a Python library and demo video showcasing these ideas provides a practical framework for further experimentation and discussion, offering valuable insights into the potential of modular pipelines in enhancing image and video understanding.
