Abstract

The invention relates to a digital pathological full-slice retrieval method and belongs to the technical field of digital image processing techniques. Aiming at the problem that the conventional content-based digital pathological image method is difficultly applied to digital pathological full-slice retrieval, the invention provides a quick retrieval method which is applied to a database stored with a large number of digital pathological full-slices, adapts to large variation of querying image sizes, can provide accurate reference information for a doctor in clinical diagnosis, and effectively improves the diagnosis quality of the doctor in the pathology department.

Description

technical field [0001] The invention relates to the technical field of digital image processing, in particular to a digital pathology full slice image retrieval method. Background technique [0002] Digital pathological full slide is to convert pathological slices into high-magnification large-scale digital images that can be displayed, transmitted and processed by a computer through a dedicated scanning imaging system. In clinical diagnosis, a large number of digital slides of diagnosed pathologies are saved, forming a valuable case database. Cancer diagnosis based on pathological images is a job that requires a high level of doctor experience. However, most pathologists in remote areas of my country cannot accurately diagnose cancer using pathological slices. This urgently requires a computer-aided diagnosis algorithm for Doctors provide relevant confirmed cases as diagnostic reference, and gradually improve their diagnostic level. [0003] The traditional text-based imag...
