Independent Component Analysis and Neural Networks Applied for Classification of Malignant, Benign and Normal Tissue in Digital Mammography

Summary

Objectives : This paper proposes an efficient method for the discrimination and classification of mammograms with benign, malignant and normal tissues.

Methods : The proposed method consists of selection of tissues, feature extraction using independent component analysis, feature selection by the foiward- selection technique and classification of the tissue by the multilayer perceptron.

Results : The method is tested for a mammogram set of the MIAS database, resulting in a 97.83% success rate, with 98.0% specificity and 97.5% sensitivity.

Conclusion : The proposed method showed a good classification rate. The method will be useful for early cancer diagnosis.
