Classification of digital mammograms using multi-resolution histogram features
A classification approach of digital mammograms using multi- resolution histogram representation in conjunction with kernel-based learning methods was presented. The approach didn't rely on the feature selection step and learned to classify various kinds of Region Of Interest (ROI) as normal/abnormal using its high-dimensional multi-resolution histogram features. Receiver Operating Characteristic (ROC) analysis of classification performance of the proposed approach shows that the sensitivity is about 89% and the Area Under Curve (AUC) is nearly 0.91. Compared to previous approaches
the proposed approach does not need to select abnormality-specific features so that it can detect various kinds of abnormalities simultaneously
which simplifies the detection process and improves the detection efficiency. The results demonstrate that multi-resolution histogram features can clearly distinguish the normal or abnormal classes in mammograms and the feature selection step of certain classification tasks can be eliminated or limited by using kernel-based learning method.
