Lightweight Transformer-Based Lithology Identification with Multi-Scale Feature Fusion
工程科学与技术岩石薄片的岩性识别是揭示储层结构与资源分布的重要环节。然而，受多尺度纹理复杂和相似岩性差异细微的影响，现有模型在特征提取充分性与参数效率之间难以平衡。为此，本文提出一种基于ECSwin-Rock（Efficient Expansion–Compression Swin Transformer for Rock Recognition）的高效岩石薄片识别网络。该模型以Swin Transformer block为基本单元构建层次化特征框架，在输入端引入多尺度融合模块（MFM）以捕获不同粒级纹理特征 ...
