Nasopharynx cancer prognosis characteristic determination method, system and device and storage medium

The invention discloses a nasopharynx cancer prognosis characteristic determination method, system and device and a storage medium, and the method comprises the steps: pathological image preprocessing: carrying out the dyeing standardization processing of a pathological image through a color normalization method based on dyeing separation; automatically segmenting a focus area of the preprocessed pathological image through a segmentation network to obtain a segmented image; cutting the segmented image to obtain a target image block; performing feature dimension reduction on the target image block through principal component analysis to obtain dimension reduction data; according to the dimension reduction data, performing unsupervised autonomous learning through a clustering algorithm to obtain pathological image features; and finally, screening the pathological image features through feature inspection, and determining a prognosis pathological feature set. The key image features, closely related to nasopharyn
