Towards High-Resolution Industrial Image Anomaly Detection
- 双分支结构融合多尺度异常线索,捕捉细微与大面积缺陷。
- 多分辨率特征融合缓解高分辨纹理干扰,提升检测鲁棒性。
- 动态检测器池适配不同区域,降低计算开销,适合工业部署。
当前异常检测方法多聚焦于低分辨率场景。高分辨率图像中,传统下采样常导致细微异常区域漏检,因细粒度判别信息丢失。尽管已有进展,近期研究通过轻量网络或简单图像分块与集成方法提升检测分辨率,但仍难以满足工业场景对精度与效率的实际需求。为此,我们提出HiAD——一种通用的高分辨率异常检测框架,可在有限计算资源下检测高分辨率图像中不同尺寸的异常区域。HiAD采用双分支架构,跨尺度整合异常线索,全面捕捉细微与大范围异常;引入多分辨率特征融合策略,应对高分辨率图像中的细粒度纹理变化挑战;并通过检测器池与多种分配策略,根据局部特征自适应选择检测器,平衡性能与计算成本。我们在自建的高分辨率基准数据集MVTec-HD、VisA-HD及真实世界数据集RealIAD-HD上进行大量实验,验证了HiAD的优越性能。代码已开源:https://github.com/cnulab/HiAD。
原文摘要 · Abstract (English)
Current anomaly detection methods primarily focus on low-resolution scenarios. For high-resolution images, conventional downsampling often results in missed detections of subtle anomalous regions due to the loss of fine-grained discriminative information. Despite some progress, recent studies have attempted to improve detection resolution by employing lightweight networks or using simple image tiling and ensemble methods. However, these approaches still struggle to meet the practical demands of industrial scenarios in terms of detection accuracy and efficiency. To address the above issues, we propose HiAD, a general framework for high-resolution anomaly detection. HiAD is capable of detecting anomalous regions of varying sizes in high-resolution images under limited computational resources. Specifically, HiAD employs a dual-branch architecture that integrates anomaly cues across different scales to comprehensively capture both subtle and large-scale anomalies. Furthermore, it incorporates a multi-resolution feature fusion strategy to tackle the challenges posed by fine-grained texture variations in high-resolution images. To enhance both adaptability and efficiency, HiAD utilizes a detector pool in conjunction with various detector assignment strategies, enabling detectors to be adaptively assigned based on patch features, ensuring detection performance while effectively controlling computational costs. We conduct extensive experiments on our specifically constructed high-resolution anomaly detection benchmarks, including MVTec-HD, VisA-HD, and the real-world benchmark RealIAD-HD, demonstrating the superior performance of HiAD.
