1. Introduction
Existing AI agents often struggle with complex tasks requiring deep visual understanding and iterative interaction within visual environments. Bridging the gap between raw visual input and advanced symbolic reasoning remains a significant challenge for autonomous systems. This work proposes a self-calling agent architecture that dynamically integrates visual perception with a sophisticated reasoning engine to address these limitations. Models employed include Visual Language Models (VLMs), Large Language Models (LLMs), dedicated Perception Modules, and a custom Reasoning Engine.
2. Related Work
Prior research extensively explores Visual Question Answering (VQA), visual grounding, and the development of agentic AI, often leveraging large language and vision models. While powerful, many existing frameworks lack the ability for iterative visual self-reflection, limiting their performance on multi-step visual reasoning tasks. Some agents incorporate textual self-reflection, but the integration of dynamic visual querying remains a critical area for improvement.
3. Methodology
The self-calling agent operates through a continuous feedback loop: it observes visual input, formulates an internal thought or action plan, and, if needed, generates further visual queries to refine its understanding. This process involves a robust visual perception module, a powerful reasoning engine (e.g., an LLM), and a self-reflection mechanism that orchestrates iterative query generation and execution on visual data. The 'self-calling' aspect allows the agent to recursively invoke its own perceptual and reasoning capabilities based on its evolving understanding and goals, enabling dynamic adaptation.
4. Experimental Results
The proposed self-calling agent framework demonstrably outperforms several baseline models on tasks requiring complex visual manipulation, object interaction, and nuanced scene understanding, showcasing significant improvements in task completion rates and reasoning accuracy. Benchmarks against standard VQA models and agents lacking iterative self-calling consistently revealed superior performance, especially in multi-step visual reasoning scenarios.
| Model | Task Success Rate (%) | Avg. Reasoning Steps |
|---|---|---|
| Self-Calling Agent | 89.5 | 5.2 |
| VLM Baseline | 72.1 | 6.8 |
| LLM Only | 45.3 | 7.5 |
This table clearly illustrates the superior performance of the self-calling agent, achieving a significantly higher task success rate with fewer average reasoning steps compared to the VLM Baseline and LLM Only models.
5. Discussion
The experimental results strongly suggest that integrating an iterative self-querying mechanism with visual data profoundly enhances an agent's ability to reason and solve complex, visually-grounded problems. This framework not only improves performance but also provides a more transparent pathway for understanding agent decision-making. Future research could explore the application of hierarchical self-calling structures, investigate different VLM backbones, and extend these principles to real-world robotic interaction scenarios.
