Cirrhosis Classification Based on Texture Classification of Random Features

الملخص EN

Accurate staging of hepatic cirrhosis is important in investigating the cause and slowing down the effects of cirrhosis.

Computer-aided diagnosis (CAD) can provide doctors with an alternative second opinion and assist them to make a specific treatment with accurate cirrhosis stage.

MRI has many advantages, including high resolution for soft tissue, no radiation, and multiparameters imaging modalities.

So in this paper, multisequences MRIs, including T1-weighted, T2-weighted, arterial, portal venous, and equilibrium phase, are applied.

However, CAD does not meet the clinical needs of cirrhosis and few researchers are concerned with it at present.

Cirrhosis is characterized by the presence of widespread fibrosis and regenerative nodules in the hepatic, leading to different texture patterns of different stages.

So, extracting texture feature is the primary task.

Compared with typical gray level cooccurrence matrix (GLCM) features, texture classification from random features provides an effective way, and we adopt it and propose CCTCRF for triple classification (normal, early, and middle and advanced stage).

CCTCRF does not need strong assumptions except the sparse character of image, contains sufficient texture information, includes concise and effective process, and makes case decision with high accuracy.

Experimental results also illustrate the satisfying performance and they are also compared with typical NN with GLCM.
