Classification of Region of Interest in Mammograms Using Dual Contourlet Transform and Improved KNN

Abstract: Goal. Breast cancer is becoming one of the most common cancers among women. Early detection can help increase the survival rates. Feature extraction directly affects diagnosis result. In this work, a novel feature extraction method based on Dual Contourlet Transform (Dual-CT) is presented, and improved nearest neighbor (KNN) is employed to improve the classification performance. Method. This presented method includes three main sections: firstly, the Region of Interest (ROI) is cropped manually according to go… Show more

“…In addition to geometrical properties, contours obtained from a modified Single Univalue Segment Assimilating Nucleus filtered mammogram were also used in the extraction procedure. Literature is replete with different ROI extraction techniques which are not based on deep learning techniques [31]- [34]. Similarly, Xiang, et al [35] claimed that they were able to automate the extraction of ROIs even from noisy medical images using an extraction algorithm with statistical moments.…”

“…In recent years, the incidence and mortality of breast cancer have increased to a great extent, and it has become a major public health problem [1]. According to a report released by the International Agency for Research on Cancer Research (IARC) in 2012, more than 1.67 million women are affected by breast cancer every year in the world, and this number is growing [2].…”

“…Mammography is the most effective, reliable, has low cost and less harmful screening for early detection of breast cancer [8]. Automatic CAD with mammography has a higher accuracy rate of detection, operation convenient speeds up the diagnostic procedure, and saves the medical resources [9]. Further, the breast mass plays a distinctive sign in breast cancer diagnosis.…”
