Image Processing for Computer Graphics
Image processing is concerned with the analysis and manipulation of images by computer. The focus of this book is to provide a thorough treatment of image processing with an emphasis on those aspects most used in computer graphics. Throughout, the authors concentrate on describing and analyzing the underlying concepts rather than on presenting algorithms or pseudocode. As befits a modern introduction to this topic, a good balance is struck between discussing the underlying mathematics of the subject and the main topics covered: signal processing, data discretization, the theory of colour and different colour systems, operations in images, dithering and half-toning, warping and morphing, and image processing.
Why Read This Book
Read this book if you want a conceptual understanding of how image processing supports computer graphics workflows. It is especially useful for learning the mathematical foundations behind common graphics techniques and for connecting signal-processing ideas to visual computing problems.
Who Will Benefit
Computer graphics students, engineers, and researchers who want a theory-first introduction to image processing. It is also a good fit for readers with an interest in visual effects, color representation, geometric image transformations, and the mathematical basis of image manipulation.
Level: Intermediate — Prerequisites: Readers should be comfortable with basic calculus, linear algebra, and fundamental signal-processing concepts. Prior exposure to computer graphics or digital image concepts will help, but the book is intended as an accessible introduction to the subject.

How It Compares
Compared with more implementation-heavy image processing texts, this book leans more toward theory and the conceptual foundations needed in computer graphics. It is less of a cookbook than practical references like Gonzalez and Woods-style image processing books, and more focused on the math and graphics-oriented use cases than on exhaustive algorithm catalogs.
