Magnetic Resonance Imaging (MRI) is a vital tool in diagnosing and planning treatment for neurological disorders, offering detailed views of brain structures. Yet, traditional manual interpretation is time-consuming and prone to variability. This book presents six novel automated brain extraction (skull stripping) methods developed from my doctoral research to improve accuracy, efficiency, and consistency in MRI brain tissue segmentation. Using advanced computational techniques such as fuzzy logic, Helmholtz free energy, bond number, block truncation coding, morphological operations,...
