A rock thin section image segmentation method based on foreground-background divide and conquer and layered color

This invention proposes a rock thin section image segmentation method based on foreground / background divide-and-conquer and layered color processing. The method first performs color space transformation and principal component analysis (PCA) dimensionality reduction on the rock thin section image to construct a single-channel structural representation for segmentation. Then, a first global segmentation is performed based on a level set model to achieve preliminary extraction of macroscopic mineral structures. Subsequently, based on the initial segmentation results, the image is divided into foreground and background regions, and enhancement channels are selected in different color spaces for each region to perform a second-stage level set segmentation. Specifically, the background region recovers weak contrast structural information by enhancing chromaticity differences, while the foreground region improves the separation ability of fine grains by enhancing texture contrast. Finally, the two segmentation results are fused, and combined with region filtering and morphological optimization, the final rock thin section segmentation result is obtained. This method can effectively improve the accuracy and stability of rock thin section image segmentation under complex lithological conditions.
