A robust approach for subject segmentation of medical Images: Illustration with mammograms and breast magnetic resonance images

Abstract

Medical image segmentation techniques are used to segment subject (suspicious lesions or organs)in medical images in order to provide physicians with accurate information about size, location, or shape characteristics, and therefore are an important technology for clinical diagnosis. However, existing segmentation methods suffer from low accuracy, high complexity, low robustness, and lack of versatility. This paper presents a novel, robust medical image segmentation technique that not only addresses these shortcomings, but also preserves the advantages of existing methods, achieving high image segmentation accuracy. In order to illustrate the excellent results delivered by the proposed progressive support-pixel correlation statistical method (PSCSM) for real medical images, experimental data are categorized as computer-simulated images, actual single-spectral mammograms, and multi-spectral breast magnetic resonance images (MRI). Finally, we compare the experimental results with those of several well-known existing and competitive image segmentation algorithms to confirm the advantages and contributions of the proposed method.
