Abstract: This invention discloses a method and system for the segmentation and clustering of nuclei based on single-cell pathological images. The contour tracing method is used to calculate all the closed contours existing in the pathological tissue images; and optimizes the contours to obtain the segmented images of the nuclei. Then, according to the mask image corresponding to the segmented images of the nuclei, the segmented images of the nuclei are divided into individual nucleus images; the influencing features of the nuclei in the corresponding area are extracted through the mask image; through feature selection, redundant features are removed, and then the UMAP feature reduction method is used to select the two most important features for clustering the nuclei. By first segmenting and dividing the nucleus area in the pathological images, and then using the divided single nucleus for feature extraction, the basis for clustering is made more objective.
