With the increase of computer processing power, people use computer processing objects to slowly shift from characters to images. Compared with the information of the character type, the image information is much more complicated, so it is more complicated to process the characters on the computer than the image processing. After the invention of digital computers, digital image processing took various advantages over analog image processing. A broad range of techniques and methods, in the form of a variety of algorithms, came into existence. This book is aimed to cover the concept and scope of image processing, discuss the various steps and methodologies involved in a typical image processing, and applications of image processing tools and processes in the frontier areas.
