ZERO: Multi-modal Prompt-based Visual Grounding

Abstract: Recent advances in artificial intelligence have led to the emergence of foundation models, large-scale pre-trained neural networks that serve as versatile starting points for a wide range of downstream tasks. In this work, we present ZERO, a zero-shot multi-prompt object detection model specifically designed for robust, production-ready deployment across diverse industrial domains. ZERO integrates direct image input with multiple user-defined prompts, which can include both textual and visual cues, and processes them through dedicated encoders to generate accurate detection outputs. The model architecture is optimized for scalability, with a total of 1.033 TFLOPS and 622.346 million parameters, and is trained using a domain-specific image database exceeding one billion images. For the CVPR 2025 Foundational Few-Shot Object Detection (FSOD) Challenge, we introduce a domain-specific fine-tuning strategy that emphasizes prompt diversity and conservative pseudo-labeling, enabling effective adaptation to new domains with minimal supervision. Our approach demonstrates practical advantages in flexibility, efficiency, and real-world applicability, achieving strong performance on the RF20VL-fsod benchmark despite limited annotation budgets. The results highlight the potential of prompt-driven, data-centric AI for scalable and adaptive object detection in dynamic industrial environments.
