Digital image processing deals with the usage of computer-aided algorithms for extracting useful information from an image. Biosignals and medical images play a pivotal role in the health care sector for disease diagnosis and therapeutic planning. The Simulation role is an inevitable tool in science and technology. This book focuses on the processing of medical images using computer-aided algorithms developed in MATLAB. MATLAB is a user friendly software that gains prominence in science and engineering disciplines. MATLAB codes are also included in each chapter, which gives a lot of insights to beginners doing research in medical image processing. Simple, easy, and step-by-step practical illustration with conceptual ideas make the book much preferable to the beginner and the intermediate compared with other books currently in the market. This book will also be beneficial for undergraduate and postgraduate students doing their academic projects and research works in image processing.
