Latest 50 papers on object detection: Dec. 13, 2025

Object detection, the cornerstone of perception in AI, continues to evolve at an astonishing pace. From enabling self-driving cars to powering automated industrial processes and even assisting scientific discovery, its impact is undeniable. However, real-world complexity—adverse weather, sparse data, tiny objects, and the need for real-time inference—constantly pushes the boundaries of current systems. Fortunately, recent breakthroughs, as highlighted by a collection of cutting-edge research, are addressing these challenges head-on, ushering in an era of more robust, efficient, and interpretable object detection.

The Big Ideas & Core Innovations

The central theme across much of this year’s research is the synergistic integration of multiple data modalities and advanced architectural designs to boost detection robustness and efficiency. Papers like “BEVDilation: LiDAR-Centric Multi-Modal Fusion for 3D Object Detection” by researchers from The Hong Kong Polytechnic University, and “GraphFusion3D: Dynamic Graph Attention Convolution with Adaptive Cross-Modal Transformer for 3D Object Detection” from Nanjing University of Information Science and Technology, exemplify this trend. They demonstrate how intelligently fusing LiDAR, RGB, and even spectral data can overcome the limitations of individual sensors, particularly for 3D object detection in complex environments. BEVDilation, for instance, proposes a LiDAR-centric approach that uses image features as implicit guidance to reduce depth estimation noise, while GraphFusion3D introduces an Adaptive Cross-Modal Transformer to dynamically integrate 2D image features with 3D point cloud representations.

Another significant innovation lies in tackling the notorious small object detection problem. The paper “Enhancing Small Object Detection with YOLO: A Novel Framework for Improved Accuracy and Efficiency” and “DFIR-DETR: Frequency Domain Enhancement and Dynamic Feature Aggregation for Cross-Scene Small Object Detection” from Shanghai Jiao Tong University, show how techniques like image slicing, super-resolution, and frequency domain enhancement can dramatically improve the clarity and detectability of tiny, often densely packed objects in aerial imagery and diverse scenes. Similarly, “MKSNet: Advanced Small Object Detection in Remote Sensing Imagery with Multi-Kernel and Dual Attention Mechanisms” introduces multi-kernel selection and channel attention to capture fine-grained spatial details, crucial for remote sensing applications.

Beyond raw performance, efficiency and real-time capabilities are paramount. “SSCATeR: Sparse Scatter-Based Convolution Algorithm with Temporal Data Recycling for Real-Time 3D Object Detection in LiDAR Point Clouds” and “LeAD-M3D: Leveraging Asymmetric Distillation for Real-time Monocular 3D Detection” from DeepScenario, ETH Zurich, and TU Munich, stand out by presenting methods that achieve impressive speedups and state-of-the-art accuracy without compromising on computational cost. SSCATeR, for instance, significantly reduces operations by reusing temporal data, ideal for embedded systems, while LeAD-M3D uses asymmetric knowledge distillation to achieve real-time monocular 3D detection without LiDAR. For those dealing with catastrophic forgetting, “You Only Train Once (YOTO): A Retraining-Free Object Detection Framework” from Politeknik Negeri Bandung, offers a unique solution by decoupling localization from classification, enabling efficient adaptation to new product categories in retail without retraining.

Finally, the growing need for robustness in challenging conditions and improved interpretability is addressed. “Salient Object Detection in Complex Weather Conditions via Noise Indicators” introduces noise indicators to enhance object detection in adverse weather, and “OWL: Unsupervised 3D Object Detection by Occupancy Guided Warm-up and Large Model Priors Reasoning” by researchers from Xiamen University, leverages large model priors for unsupervised 3D detection, significantly reducing annotation costs. For interpretability, “Concept-based Explainable Data Mining with VLM for 3D Detection” from The University of Tokyo, uses Vision-Language Models to mine rare, safety-critical objects, focusing on explainability for autonomous driving.
