A rock slice image segmentation method based on feature cooperation and parameter regulation

This invention proposes a rock thin section image segmentation method based on feature collaboration and parameter control. The method first performs color space transformation and principal component dimensionality reduction on the image to construct a single-channel structural representation suitable for segmentation. Then, it fuses global semantic features extracted by a deep network with local statistical features of the image. A parameter prediction module generates dynamic weight parameters for the level set energy term to guide the differentiated evolution of the contour in different structural regions. The proposed dynamic parameters are incorporated into a generalized local fuzzy fitting level set model to achieve stable segmentation of multi-scale particles, weak contrast boundaries, and complex texture regions. Finally, region selection and structural consistency constraints suppress noise pseudo-regions. This method significantly improves the adaptability and detail integrity of segmentation under complex lithological conditions, providing a robust and efficient solution for automated rock thin section analysis.
