Abstract
The clustered microcalcifications on X-ray mammogram provides an important cue for early detection of breast cancer. Texture analysis methods can be applied to detect clustered micro calcifications in digitized mammograms. The clustered microcalcifications on X-ray mammogram provides an important cue for early detection of breast cancer. Texture analysis methods can be applied to detect clustered micro calcifications in digitized mammograms. In this study a novel 2 stage method for mammogram segmentation is implemented to facilitate automatic segmentation of micro calcification. The first stage is the Modified combined morphological spectral unsupervised Image segmentation. The first stage includes watershed transform, anisotrophic filtering technique, band pass filtering scheme, gradient synthesisation and Complex Wavelet Transform (CWT) subband extraction. The second stage of the segmentation scheme is the Random walkers segmentation technique. Finally, features are derived from the Ridgelet subbands of the segmented image. The cooccurrence matrix features are also used for classification. This study also implements the Support Vector Machines (SVM) for effective classification of Mammogram into Benign or malignant mammogram. The validation of the classification scheme was performed by using the Receiver Operating Curve (ROC) analysis, the overall sensitivity of the technique measured by the value of Az which was found to be ranging from 0.8-0.928.
