Sandstone petrographic analysis integrating deep learning and image processing
“In response to the strong subjectivity of manual identification in sandstone petrographic analysis, traditional image analysis methods often focus on a single task and lack systematic quantitative characterization capabilities, the research team proposes a set of intelligent analysis solutions that cover processes and techniques for thin section image fusion. A framework for sandstone petrographic analysis has been established to provide a solution to the problem of quantitative characterization of sandstone.”
