Abstract：To solve the problem of low accuracy and time-consuming in the traditional switching between single polarization and orthogonal polarization systems for the analysis of rock slices and content estimation under microscope,a combined segmentation method of rock slice image in chrominance luminance space was designed.Firstly,the single polarized image and the orthogonal polarized image from the same field of view were decomposed separately in the chromatic and bright space.Then,the chromaticity image was sub-jected to bilateral filtering to suppress noise and remove texture.The difference between the filtered two chromaticity images was calculated,and the final segmentation result was obtained by using K-Means clus-tering algorithm and watershed segmentation algorithm in sequence.The research results can provide guid-ance for geologists to identify rock slices.
