Abstract

Semantic segmentation plays a fundamental role in computer vision, underpinning applications such as autonomous driving and scene analysis. Although dual-branch networks have marked advancements in accuracy and processing speed, they falter in the context extraction phase within the low-resolution branch. Traditionally, square pooling is used at this juncture, leading to the oversight of stripe-shaped contextual information. In response, we introduce a novel architecture based on a deep aggregation pyramid, engineered for both real-time processing and precise segmentation. Central to our approach is a pioneering contextual information extractor designed to expand the effective receptive fields and fuse multi-scale context from low-resolution feature maps. Additionally, we have developed a feature fusion module to enhance the integration and differentiation of high-level semantic information across branches. To further refine the fidelity of segmentation, we implement dual deep supervisions within the high-resolution branchs intermediate layer, concentrating on boundary delineation and global features to enrich spatial detail capture. Our comprehensive experimental analysis, conducted on the Cityscapes and CamVid datasets, affirms MSSINets superior performance, showcasing its competitiveness against existing leading methodologies across a variety of scenarios.
MSSINet:基于多尺度条带集成的实时分段技术
语义分割在计算机视觉中扮演着重要角色,是自动驾驶和场景分析等应用的基础。虽然双分支网络在精确度和处理速度上有显著进步,但在低分辨率分支的上下文提取阶段却出现了问题。传统上,在这一关头使用的是方形池,导致条纹状上下文信息被忽略。为此,我们引入了一种基于深度聚合金字塔的新型架构,可实现实时处理和精确分割。我们方法的核心是开创性的语境信息提取器,旨在扩大有效感受野,并从低分辨率特征图中融合多尺度语境。此外,我们还开发了一个特征融合模块,以加强跨分支的高级语义信息的整合和区分。为了进一步提高分割的保真度,我们在高分辨率分支中间层实施了双重深度监督,集中于边界划分和全局特征,以丰富空间细节捕捉。我们在 Cityscapes 和 CamVid 数据集上进行了全面的实验分析,证实了 MSSINets 的卓越性能,展示了它在各种场景下与现有领先方法的竞争力。
