Abstract
Real-time scene description and interpretation are essential for diverse applications
such as surveillance, interactive media, and automated video analysis. However,
most existing methods rely heavily on large-scale labeled datasets, thereby limiting
their adaptability in dynamic or previously unseen scenarios. In this work, we
propose a novel mixed-model framework that integrates Vision-Language Models
(VLMs), Large Language Models (LLMs), and lightweight object detection networks
(e.g., MobileNet-SSD) through advanced prompt engineering. By leveraging zeroshot
learning, our approach generates contextually rich scene descriptions without
requiring domain-specific or task-specific retraining. The prompt engineering component
reduces sensitivity to subtle linguistic variations, enhancing robustness across
diverse input formulations. Furthermore, the lightweight detector ensures real-time
performance, making the framework suitable for resource-constrained environments.
To address ethical and fairness considerations, we incorporate bias mitigation strategies
that limit the propagation of harmful stereotypes from large-scale pretraining
data. Experimental evaluations on multiple open-domain scenarios demonstrate
that our system offers reliable and efficient scene interpretation, maintaining high
accuracy in challenging conditions where traditional supervised techniques often
fail. This research paves the way for more flexible, scalable, and responsible visionlanguage
systems capable of operating effectively in real-world, zero-shot contexts.
