A digital slice image storage and display method based on image pyramid layering

Abstract

The invention relates to a digital information processing technology, in particular to a digital slice image storing method and a digital slice image displaying method based on image pyramid layering, wherein the storing method comprises the following steps that: 1, slice image elements are obtained, and are marked into a zeroth layer, image data in the zeroth layer is divided into data blocks in the dimension of 256*256, and a corresponding coordinate position (X, Y) is recorded; 2, the center of the image elements in a previous layer is used as a base point, the line and row dimension is reduced according to a set proportion, then, sampling is carried out, and the layer number is marked; 3, the second step is repeated until the obtained total data amount reaches the set layer number; and 4, the image elements obtained through sampling are used for building a digital slice pyramid according to the marking sequence. The methods provided by the invention have the advantages that under the condition of the limited network bandwidth, the close progressive of the images can be fast show; and through the image displaying method provided by the invention, the requirement on the browsing terminal equipment performance is greatly reduced, and the digital slice browsing and displaying efficiency is enabled to reach the clinic diagnosis requirements.

Description

technical field [0001] The invention relates to digital slice image processing technology, in particular to a digital slice image storage and display method based on image pyramid layering. Background technique [0002] At present, there is a shortage of pathologists in grass-roots hospitals in China, and the level of pathological diagnosis is limited. High-quality pathological diagnosis resources are mainly concentrated in big cities and large hospitals. For grass-roots patients who want to obtain accurate pathological diagnosis, patients or relatives and friends often send pathological slides to the pathology department of higher-level hospitals in person. Consultation, which not only makes patients spend a lot of time waiting for diagnosis results, but also makes patients pay more. Digital pathology can enable grassroots pathologists and patients to obtain accurate pathological diagnosis opinions without going out, realize a true "one-stop pathological consultation servic...
