摘要:

地面云图像分割是光伏功率预测的重要研究领域。当前深度学习方法主要集中在编码器-解码器架构的改进上。然而,现有方法存在几个限制:(1)它们依赖于扩张卷积进行多尺度上下文提取,缺乏部分特征有效性和通道间的互操作性;(2)基于注意力的特征增强实现忽视了精度与吞吐量的平衡;(3)解码器修改未能在层次局部特征之间建立全局依赖关系,限制了推理效率。为解决这些挑战,我们提出了MPCM-Net,一个多尺度网络,整合了部分注意力卷积与Mamba架构,以提高分割精度和计算效率。具体而言,编码器包含MPAC,其中包括:(1)一个MPC块,包含ParCM和ParSM,能够跨多尺度云形实现全局空间交互,以及(2)一个MPA块,结合ParAM和ParSM,以减少计算复杂性提取判别性特征。在解码器一侧,采用M2B来通过SSHD缓解上下文损失,同时在空间和尺度维度上实现深度特征聚合,保持线性复杂度。作为对社区的重要贡献,我们还引入并发布了CSRC数据集,这是一个清晰标签、细粒度分割基准,旨在克服现有公开数据集的关键限制。在CSRC上的大量实验显示,MPCM-Net在现有方法中表现优异,实现了分割精度与推理速度之间的最佳平衡。数据集和源代码将在https://github.com/she1110/CSRC上提供。

英文摘要:

Ground-based cloud image segmentation is a critical research domain for photovoltaic power forecasting. Current deep learning approaches primarily focus on encoder-decoder architectural refinements. However, existing methodologies exhibit several limitations:(1)they rely on dilated convolutions for multi-scale context extraction, lacking the partial feature effectiveness and interoperability of inter-channel;(2)attention-based feature enhancement implementations neglect accuracy-throughput balance; and (3)the decoder modifications fail to establish global interdependencies among hierarchical local features, limiting inference efficiency. To address these challenges, we propose MPCM-Net, a Multi-scale network that integrates Partial attention Convolutions with Mamba architectures to enhance segmentation accuracy and computational efficiency. Specifically, the encoder incorporates MPAC, which comprises:(1)a MPC block with ParCM and ParSM that enables global spatial interaction across multi-scale cloud formations, and (2)a MPA block combining ParAM and ParSM to extract discriminative features with reduced computational complexity. On the decoder side, a M2B is employed to mitigate contextual loss through a SSHD that maintains linear complexity while enabling deep feature aggregation across spatial and scale dimensions. As a key contribution to the community, we also introduce and release a dataset CSRC, which is a clear-label, fine-grained segmentation benchmark designed to overcome the critical limitations of existing public datasets. Extensive experiments on CSRC demonstrate the superior performance of MPCM-Net over state-of-the-art methods, achieving an optimal balance between segmentation accuracy and inference speed. The dataset and source code will be available at https://github.com/she1110/CSRC.
