Example Embodiment

[0035] Reference figure 1 The medical image diagnosis system based on migration core matching tracking of the present invention includes: an image preprocessing module, an image feature extraction module, an image migration core matching tracking diagnosis module, and an image unmarked sample test module. These modules are connected in turn. The image migration core matching tracking diagnosis module includes an image target domain identification sample training sub-module and an image source domain identification sample training sub-module. The image target domain identification sample training submodule completes the training of the image target domain with identification samples, generates an image training classifier with target domain identification samples, and transmits the classifier to the image source domain's identified sample training submodule; The identification sample training sub-module of the image source domain uses the training classification of the target doma...

Abstract

The invention discloses a medical image diagnosing system and a diagnosing method based on migrated nuclear matching tracing. The whole system comprises an image preprocessing module, an image feature extracting module, an image migrated nuclear matching tracing diagnosing module and an image unidentified sample testing module. The image preprocessing module completes the redundancy removal of original images and the equalization strengthening processing of histograms. The processed images are extracted to obtain gray level cooccurrencematrixes, Hu matrixes, and Brushlet and Contourlet features as a sample set, thus a source field, a target filed identified training sample set and a target filed unidentified training sample set are obtained. The migrated nuclear matching tracing learning is carried out on the source field and the target filed identified training sample set, thus a refreshed target field training sample set and a training classifier are obtained. The training classifier is used for classifying and diagnosing the unidentified testing samples and outputting final diagnosing results. The invention can relieve the defect that the quantity of medical reference samples is few, effectively enhance the medical image diagnosing identification rate and can be used for assisting the clinical diagnosing of medical images.

Description

technical field [0001] The invention belongs to the technical field of image processing, in particular to medical image processing, which can be used for clinical auxiliary diagnosis of medical images. Background technique [0002] With the rapid development of computer and related technologies and the maturity of graphics and image technology, medical imaging diagnosis is a key research direction in the medical field at home and abroad.
